DETROIT (WOOD) — Lake Michigan broke the high-water level record during March. It’s the third straight month the high-water level record has been broken.
The U.S. Army Corps of Engineers said lakes Michigan, Huron, St. Clair and Erie set new monthly water level records for March 2020, which were previously set in 1986.
Officials say water levels are expected to rise toward their seasonal peaks in the coming months and will continue to be near or reach above record high water levels.
Erosion also continue to be a big concern as the levels remain high.


Tunnel contractors have commenced work at the 30MW Pingston hydro project in southern British Columbia, Canada.
The 4km long tunnel is expected to take approximately 12 months to complete. Construction work on the power house, intake and transmission interconnection are also moving forward. Designs for the headpond, weir and intake have been completed and will be undertaken as a separate contract. Orders have also been placed for turbine/generation equipment, scheduled for delivery in early 2002. Site works including roads, penstock grading and clearing are essentially complete.
The Pingston project is being developed by Canadian Hydro in conjunction with its 50% joint venture partner, Great Lakes Power. Com-missioning is scheduled to take place in July 2002. The power could be sold to BC Hydro or Alberta utilities.
Meanwhile, BC Hydro has awarded the contract to carry out the seismic upgrade of two dams at the Elsie Lake reservoir, in Vancouver Island, British Columbia, to Copcan Contracting from Nanaimo. The work involves excavating, removing and replacing loose liquefiable materials within the body of the two earth dams. The majority of this work is expected to be completed by November 2001.
In October 2000, a temporary spillway channel was constructed to keep the reservoir level below that of the loose layers. When the earthwork is complete, this temporary spillway channel will be plugged with concrete to re-establish normal reservoir levels.
The Elsie Lake reservoir is impounded by four saddle dams and a main dam provides storage for the Ash river hydro plant. Water is transported through a 7.5km long tunnel and pipeline to the 27MW power house on Great Central Lake.


By the end of 2012, the installed capacity of electric power in China reached 1,144,910 MW.[more]
The Merowe Hydropower Station is on the Nile River in Sudan. It has a 10-km-long earth and rock dam with a 290-m x 44.5-m powerhouse. Its installed capacity reaches 1,250 MW. It has auxiliary facilities and 21,511-ton metal structure.

It was 2,393.86 ft., 3 ft short of orange-alert level, on Sunday morning
Despite a lull in rainfall and increased power generation at the Moolamattom power house, the water level at Idukki reservoir continued to rise, though slowly, on Sunday. The water level at 10 a.m. was 2,393.86 ft., nearly 3 ft short of the orange alert level, as per the new rule curve fixed by the Central Water Commission. The orange alert level is 2,396.85 ft and the red alert level is 2,397.85 ft.
Even if the shutters of the Idukki dam were opened and water released, there would be no flooding, said the officials of the Kerala State Electricity Board (KSEB). “The water level of the Periyar and Pampa rivers are at a low this year. The allowed level in the Periyar river is 9 m and the present water-flowing level is below 1 m. The allowed level in the Pampa is 6 m and the present water-flowing level is 1.6 m,” said an official of the KSEB (Transmission, System Operation).
The power generation has been raised to 9.504 mu at the Moolamattom power plant. The marketing wing collected bids and sold the extra power generated, said an official.
Water storage in the hydel reservoirs in the State is nearly 90% of the total storage level.
In other dams
The storage level in main hydel dams is Idukki (89%), Pampa (89%), Sholayar (94%), Idamalayar (88%), Kundala (91%), Mattupetty (86%), Kuttiady (66%), Thariyode (92%), Anayirangal (78%), Ponmudi (91%), Neriyamangalam (94%), Peringalkuthu (77%), Lower Periyar (60%) and Kakkad (86%).

The University of Santo Tomas said Tuesday its flood mitigation project is nearing completion, raising hopes that frequent days of swamping in the España area in Manila would soon be over.
The university's stormwater drainage project, which was started in 2018, is 75% complete according to UST Facilities Management Office Director Fr. Dexter Austria.
"The usual perils of flooding that the Manila campus endures will soon be held at bay, as the stormwater drainage flood mitigation project of the University nears completion," UST said in a Facebook post.
The project aims to replace existing drainage lines with a new drainage system and provide detention facilities for floodwater to control water spillage within the 21.5-hectare campus.
UST and its surrounding areas are frequently plagued by floodwaters during the rainy season, prompting usual class suspensions within the university.


NARANCHE STADIUM ARTIFICIAL TURF PROJECT
WET provided project management, stormwater engineering, construction oversight, and project bidding and administration services on the Butte High School Naranche Stadium turf project. Our team worked closely with the Butte School, District, Academy Sports Turf, Shaw Sports Turf, and multiple subcontractors to ensure the new artificial turf was installed according to design specifications and connected seamlessly with stormwater infrastructure in the area. The area suffers from chronic flooding due to undersized stormwater infrastructure. Runoff from the field was a major contributor to the past flooding events, so it was imperative to design a new stormwater detention system to decrease turf runoff peak flows and to integrate the detention system without impacting the new turf. WET successfully designed a system using subgrade detention under the turf. Mother Nature tested the detention system soon after the project was complete, and it successfully detained flow from a major storm event. Before and after aerial photos are shown below. The project was completed ahead of schedule and under budget.

Atbara River is one of the tributaries of the Nile River. It is the most northerly tributary of the Nile flowing from the Ethiopian Highlands. It has two branches Setit River (called in Ethiopia Tekeze) and Upper Atbara River. The total catchment area of Setit and Upper Atbara rivers is about 97,000 km2 (68,000 km2 and 29,000 km2 respectively).
Atbara is a seasonal river with annual average flow amounts to 12 billion m3 (bcm). Khashm ElGirba Dam (KED) was constructed on Atbara River in 1964 with a storage capacity of 1.3 bcm. Since then the KED lost about 65% of its storage capacity due to sedimentation. Currently there are two dams (DCUA) under construction, each on one of the two branches (Setit, Upper Atbara) with total storage capacity about 3.700 bcm (2.52 bcm for Burdana reservoir on Setit River and 1.18 bcm for Rumela one on Upper Atbara River). The two reservoirs are linked by a channel flowing from Burdana to Rumela. Several recommendations are provided by a Consultant to operate the Atbara Dam Complex (ADC) − (the two reservoirs plus KED). The main objective of the project is irrigation, drinking water supply and hydropower generation.
In this paper the experience gained from the reservoirs management in Sudan, in particular KED will be reviewed and discussed. Sediment management will be the core of the operation rules which will govern ADC. This means that the sustainability of the reservoir to serve its purposes, on which the feasibility study is conducted, mainly depends on how ADC will be operated.
The impact of the upstream development on the ADC operation (i.e. Ethiopia Tekeze Dam − called TK5) will be examined. The paper concludes with several recommendations to maximize the benefits out of ADC reservoir.

Sowy River Wikipedia
The Sowy River is an artificial drainage channel in Somerset, England.
It is a 7.5-mile (12.1 km) embanked channel which starts at Monks Leaze clyce below Langport, and carries excess water from the River Parrett to the King's Sedgemoor Drain, from where it flows to the estuary by gravity, rejoining the Parrett near Dunball wharf. Construction of the channel, together with improvements to the King's Sedgemoor Drain and the rebuilding of the clyce at Dunball, to create a fresh water seal which prevents salt water entering the drain from the river, cost £1.4 million, and was completed in 1972. The scheme has resulted in less flooding on Aller Moor.
During 2009 and 2010 work was undertaken to upgrade sluice gates, watercourses and culverts to enable seasonal flooding of Southlake Moor during the winter diverting water from the Sowy River onto the moor. It has the capacity to hold 1.2 million cubic metres as part of a scheme by the Parrett Internal Drainage Board to restore ten floodplains in Somerset. In spring the water is drained away to enable the land to be used as pasture during the summer. The scheme is also used to encourage water birds.

This project will reduce the risk of flooding of homes, yards and streets through an upgraded storm drain system that includes detention pond improvements, upgraded storm drain pipe and new storm drain inlets.
The storm drain system in the Brassiewood Drive area was designed and constructed using outdated drainage criteria and is not able to handle large rain events. This causes homes and streets to flood during heavy rainfall. This project will reduce the risk of flooding by increasing the drainage capacity of the storm drain system.
Please tell us about your experiences with flooding through our online form. There is an option to send flood photos at the end of the form. Please have any photos that you'd like to share ready to upload before filling out the form.
Status and Timeline
The City of Austin completed an engineering feasibility study of the project area in September 2019. Based on this study we selected a solution that uses a multi-phased approach to implement the project to reduce risk of flooding in the project area. This approach will help provide flood risk reduction in a faster timeframe.
Phase 1 of the project will consist of a new storm drain line that runs along Softwood Drive and Creek Bend Drive before reaching the outfall just east of the existing flood wall into Williamson Creek. This will capture a significant portion of the stormwater that currently flows into the detention pond at the end of Aviary Cove. The project is in the final stages of the design phase. The construction is scheduled to start in Summer 2024.
Phase 2 of the project proposes to enlarge the detention pond outlet at Aviary Cove and construct a new storm drain along Pleasant Valley Road. The new outlet will capture more stormwater and lower the risk of the pond overtopping. This outlet will connect to a new storm drain system along Pleasant Valley Drive, which will convey the stormwater from the pond into Williamson Creek near the Pleasant Valley Bridge to the south. The project is currently in the design phase and construction is scheduled to start in Winter 2025.
Phase 3 of the project will include general improvements to the stormwater infrastructure throughout the neighborhood, including inlet improvements, channel improvements, and bridge culvert improvements. This project started the Preliminary Engineering (PER) phase to study options to further reduce the risk of flooding in the neighborhood. The PER is scheduled to be completed in Spring 2024.
While we are looking for and implementing potential large-scale solutions, we are simultaneously working on short-term solutions based on input we received from the community to reduce the risk of flooding. On August 19, 2021, slot drain inlets were removed from Nesting Way and were replaced with larger curb inlets. This was done to improve the flow of water and reduce the likelihood of flooding due to debris clogging the inlets. We are also working with the Austin Fire Department to ensure that road closures are in effect during large rain events.

ADB sanctions $150m loan for 140MW hydropower plant in Nepal
The Asian Development Bank (ADB) will provide a $150m loan for the construction of a 140MW hydropower plant in Nepal.
The proposed hydropower plant will be located 150 kilometers west of Kathmandu on the Seti River in Tanahu district and will require a total investment of $500m.
ADB South Asia Department Energy Division director Yongping Zhai remarked that the project is expected to help the country overcome its energy crisis that affects its economic prospects.
To ensure operations at the plant during the dry winter months, it will be fed from a 7.26km2 reservoir, making it the first major hydropower facility in the country with water storage capacity and a sediment flushing system.
Other lenders for the project include the Japan International Cooperation Agency, the European Investment Bank, and the Abu Dhabi Fund for Development.
Nepal's current total power generation capacity stands at 700MW - largely from hydropower sources but represents 1.5% of the country's total hydropower potential.

Abstract: Flood evolution exhibits a complicated non-linear dynamical process.The neural network possesses the capability of dealing with complexnon-linear dynamical systems,this paper demonstates howit can be used in flood prediction as a new approach considering the non-linear relation ship between flood evolution and its factors such as discharge,channel deformation,and so on.Based on it,the neural network approach is applied to the flow prediction of Yangtze Riverat Luoshan station.The preliminary results suggest that the phenomenon of small discharge with high level in middle reaches of Yangtse River recently,especially in 1998,is related to the downstream aggregation.And the quantitative relations between the water level variation of Luoshan station and the downstream aggregation are obtained.

UT administrator VP Singh Badnore on Friday laid the foundation stone for augmentation of water storage capacity at Sector 39 waterworks, virtually from Punjab Raj Bhawan.
While briefing about the project, MC commissioner (MCC) KK Yadav said that at present the available raw water storage capacity at the waterworks is 48 million gallons (MG), and the clear water capacity is 15 MG. This storage capacity is sufficient for the city’s half-day water requirement only. In case any of the four rising mains (pipes) from Kajauli get damaged or an electricity shutdown in Kajauli, it takes approximately one day to get the repairs done and results in a water crisis in the city.
But with the proposal to create additional raw water storage capacity by remodelling/redesigning the existing seven storage tanks, their capacity will be increased, he added.
The MCC said that the height of the raw water tanks will also be increased from 48 MG to 92 MG. He informed that the total cost of the project is Rs 39 crore, of which the Chandigarh administration has provided Rs 28 crore, and Chandigarh Smart City Limited has provided Rs 11 crore. The work will be completed in two years.
Yadav said that after the completion of this project, the total water storage capacity at the waterworks will be 109 MG, which is sufficient to meet the city’s peak daily requirement. He said that the CREST has also proposed to install floating solar panels on the raw water tanks that will have a capacity of 12 megawatts.
The governor said that the MC is providing the citizens of Chandigarh access to safe and clean water three times a day, through the project of enhancing the storage capacity of clear water tanks, provision of pumping machinery, the recycling pump house, and laying of required lines.

Effect of drainage layer on pressure drop of dual-layer glass fibrous coalescing filters
Drainage layer strategy is a common method for improving the filtration performance of a coalescing filter. In this study, we employed commercial, sub-high efficiency glass fibrous filters as drainage layers. The performance of high efficiency coalescing filters assembling the drainage layer was investigated experimentally. After drainage layer was assembled, the wet pressure drop at equilibrium stage was reduced and the pressure drop allocation exhibited obvious change. In addition, the influence of pore size, thickness and wettability of drainage layer on performance was evaluated. The pore size is a dominant factor in improving wet pressure drop at steady state. The wet pressure drop reduces gradually over pore size. The drainage layer with smallest pore size shows highest quality factor. Likewise, the thickness of the drainage layer also has a positive effect on wet pressure drop and quality factor. The coalescing filter assembling thickest drainage layer has lowest pressure drop and highest quality factor. The effect of superoleophilic drainage layer on wet pressure drop and quality factor of filter is negligible, and the superoleophobic drainage layer results in the enhancement of pressure drop and reduction of quality factor. For different coalescing filters with the same drainage layer, the smaller the pore size deviation between coalescing and drainage layer, the lower the wet pressure drop and the higher the quality factor.

Computer-Aided Modelling of Waterbodies
Analysis of the Hydraulic Effects of a Dike Relocation
It has been demonstrated on the Elbe near the town of Lenzen that numerical modelling prior to the start of construction work can accurately predict subsequent naturally occurring events.
Since the 1990s a dike relocation has been planned and carried out by the German state of Brandenburg on the river Elbe near the town of Lenzen. The Federal Waterways Engineering and Research Institute (BAW) supported the realization of the project with the help of hydraulic-morphological modelling analyses. The plan envisaged on the one hand changing the course of the elevated Elbe flood dike and reducing the flood channels in the floodplain with the dike relocation in the Lenzen-Wustrower Elbe Valley Lowlands, west of the town of Wittenberge. On the other hand, it included a modification to the location and structure of the floodplain forest plantings in the region of the dike relocation, as well as additional floodplain planting on the Lütkenwisch and Mödlich river islands, adjacent to the dike relocation area. Before the start of the project, in November 2006, the project sponsor, the German Federal Agency for Nature Conservation (BfN), requested intra-governmental assistance from the BAW in the investigation of the hydraulic consequences of these measures.
The BAW scientists used the hydronumerical model UnTRIM for their investigations and generated a two-dimensional model of the area under investigation. Following completion of the dike relocation at the end of 2009, it was possible to validate the model calculations consisting of changes in water level and volume of water flowing into and out of the area of dike relocation. This was performed by means of comparative measurements - water level and flow measurement - during the Elbe floods in March 2010, October 2010 and January 2011. 'It demonstrated that we were able to predict the natural hydraulic conditions that actually occurred accurately using the computer model', said Matthias Alexy, Dipl- Ing. a BAW engineer in the department responsible for hydraulic engineering in inland areas.
The two-dimensional depth-averaged hydronumerical model
Since secondary flow effects were assumed negligible in the specific floodplain and dike relocation areas under investigation of the Lenzen-Wustrower Elbe Valley Lowlands, the BAW engineers opted for a two-dimensional depth-averaged model based on the hydronumerical model UnTRIM.
The BAW model geometry of the Elbe section under consideration was largely based on a digital terrain model of the Elbe watercourse (DGM-W Elbe) provided by the German Federal Institute of Hydrology (BfG). Geometrical data were mainly taken from groyne registries, digital federal waterways maps, geo-referenced aerial photographs. The location and structure of existing and planned plantations, in particular the new dike protection plantations and a new floodplain forest, were required in order to factor in the flow resistance that they would cause. Hydraulic variants were simulated for a number of annual discharge series based on hydraulic records from the years 1971 - 2000, as well as preliminary key values of flood events from the state of Sachsen-Anhalt for the Wittenberge/Elbe gauge. In order to calibrate and validate the model, comparison was made with most recent on-site water level measurements. As the model works with stationary flow conditions, flood level data with relatively low flow fluctuations were selected.
The construction of the numerical grid for the Elbe section in question (El-km 470 - 489.5) envisaged a total of two high resolution meshes. The first represented the current state with the existing course of the dyke line at the start of the project. The second depicted the altered state with relocated flood protection dyke, the flood channels in the floodplain, the cutoffs in the Gandower Fährdamm (ferry levee), as well as the apertures (in total six openings) in the old dyke.
'We managed to represent the groyne bodies with a high grid resolution in the area of the river bed', said Matthias Alexy, 'and that with square elements with sides of 2m, such that the hydraulic effect of the groynes was captured without our having to specifically align the element edges to the geometry of the structures'. The BAW engineers likewise largely avoided having to orient the grid edges to terrain structures in the floodplain, so as to achieve an efficient mesh generation. Square elements with sides of 2m were also integrated into the model in these areas, in order to nonetheless capture the hydraulic effects of flood channels, cutoffs and dyke openings.
Figure 1 depicts the dyke relocation area (El-km 476.7 - 483.7) as a section of the overall model. In addition to the existing six specified apertures in the flood protection dyke, figure 1 depicts the Gandower Fährdamm (ferry levee) coursing right across the dyke relocation area. Three cutoffs ensure that this dam can let through sufficient water in the event of a flood. In addition to the eastern flood channel that ensures a connection to the central and southern ferry levee cutoffs, three further flood channels were constructed for the improvement of the discharge conditions in the area of the dyke relocation.
Thanks to the cuts made in the old flood protection dyke in 2009, the floodplain bounded by the new flood dyke between El-km 476.7 and 483.7 carries a substantial part of the total Elbe discharge. In order to simulate the flow resistance invoked by the existing vegetation, corresponding roughness values typical of the existing vegetation were integrated into the calculation model. Figure 2 shows the computed water levels along the river axis for conditions with and without the dyke relocation for a hundred year flood (HQ100 = 4020 m3/s, occurring on average once every 100 years).
Due to the enlargement of the discharge areas resulting from the dyke relocation, there is a significant drop in water levels in the case of flood events. 'For a hundred year flood with a discharge of 4020 m3/s, the drop in water level amounts to a maximum of 0.35m at the first floodplain inlet at El-km 477.3, which results in a decrease in water level of 0.2m at the upstream boundary of the model (El-km 470.0)', as Matthias Alexy states. He then elaborates on further model results. At the downstream edge of the dyke relocation area, a maximum rise in water level of 0.06m resulted in the vicinity of El-Km 483 as compared to the situation prior to the relocated flood dyke. This local water level increase is caused by the fact that around 85% of the water discharged over the dyke relocation area, amounting to 1385 m3/s, reaches the main river via the relatively narrow apertures 5 and 6. In comparison to the situation without dike relocation, however, significantly less water is discharged in the main river channel (-1170 m3/s), so that lower flow speeds prevail.
The water flowing in from the dyke relocation area through apertures 5 and 6 brings the discharge back from 2635 m3/s to 4020 m3/s over a short distance. Because of the low flow speed, the additional volume of water can initially only be discharged by means of an enlargement of the flow cross-section and thus a rise in the water levels. The difference between this higher water level and the water level further downstream results in a locally steeper water level gradient and higher flow velocities. Due to the increased water level in the main stream, the water level in the lower part of the dyke relocation area is increased to 0.08m above the water level in the main channel.
In addition to the computations for the vegetal cover in the year 2009, forecasts were also generated for various vegetation scenarios. E.g. in case of a hundred year flood and assuming fully developed vegetation in 2009 the model predicted a maximum water level increase in the upstream region of the dyke relocation area of around 0.12m compared to the [actual] vegetation state in 2009. However, the water level is still about 0.25m below that without the dyke relocation.
The water level situation at the Mödlich river island located downstream (El-km 485 - 487) remains unaffected by the dike relocation. The vegetation envisaged here (tree galleries on natural deposits of fines along the banks, scattered copses on the floodplain) exhibit a very low flow resistance, such that the water level rise - just a few millimetres - is negligible.
Around the Lütkenwisch river island that lies upstream (El-km 474 - 476), a significant decrease in the flood levels of around 0.3m at a discharge rate of 4020 m3/s due to the dike relocation is anticipated, such that the calculated rise in water level of about 0.01m owing to the planting schemes is practically negligible.
Flood: the practical test for the computational model
A flood in March 2010 enabled the first field measurements to be used for model validation. These took place after the dike relocation, which was completed at the end of 2009. 'Apart from a few discrepancies of a technical nature at the upper boundary of the model, we found a very good accordance between calculation and measurement', as Matthias Alexy reported. Subsequent flooding events in October 2010 (fig. 3) and in January 2011 confirm the good agreement between water levels and flow conditions computed in the model and those observed in the natural environment. As Alexy added: 'Our experience with the model is now flowing into the interdisciplinary research project KLIMZUG NORD. This will help us - together with our research partners - to develop a climate-adapted, integrated floodplain management system in the Biosphere Reserve Elbe Floodplain in the Lower Saxony Elbe Valley.' Based on the numerical model generated by the BAW, the impact of changed discharge and vegetation conditions on the Elbe´s water level are to be simulated using various climate change scenarios. 'We are currently basing our modelling on discharge rates of up to 5000 m3/s for future climate-induced extreme flood events.'

Client: Daelim Industrial Co., Seoul, South Korea
Contract Period: 2014-2015
GLM Engineering (Perú) was contracted as a sediment management consultant for the Upper Trishuli project in Nepal, a proposed 216 MW hydropower facility with 350 m gross head and 76 m3/s design flow. The project includes a 24m tall barrage-type dam with large radial gates on a river having 3% slope which transports material as large as boulders. The project is being designed to include settling basins to remove sand, and the principal design problems we addressed were minimization of sand and gravel entrainment by the intake, optimal flushing of sediment from the impounded reach, and hydraulic conditions at the trash rack together with exclusion of floating woody debris.
A review was performed of all prior studies, followed by site visits to advise on the physical modeling tests being performed in Kathmandu. Alternative intake configurations were tested, including both frontal and lateral configurations, as well as alternative gate configurations at the dam to facilitate sediment clearance from the intake area and to minimize the entrainment of sand and gravel. Schematic designs were prepared for incorporation into the hydraulic model and testing under a wide range of flows. There was considerable emphasis on the part of the client to minimize modifications to the original design concept for the intake, debris screen and gravel trap, none of which was performing satisfactorily, so as not to increase the project cost estimate.
After carefully observing the flow characteristics at the intake for alternative configurations, a design was developed and successfully tested, which incorporated several features which allowed the overall concept of the lateral intake to be retained, yet which yielded greatly improved performance in terms of sediment exclusion, which eliminated undesirable flow patterns at the trash rack, and which also improved gravel trap function.
This project is continuing.


Bhopal: The world’s largest floating 600 MW solar energy project to be constructed at Omkareshwar dam on Narmada river in Khandwa district of Madhya Pradesh will begin power generation by year 2022-23. The estimated investment in this project stands at Rs 3,000 crore, said an official release quoting the state’s new and renewable energy minister Hardeep Singh Dang on Tuesday.
The International Finance Corporation, World Bank and Power Grid have granted in-principle consent for providing aid for the said project development.
The primary feasibility study of the project has been completed in collaboration with the World Bank. The project is likely to begin power generation by year 2022-23, the minister said.
Dang said that the work of transmission line route survey will begin from the project area to Khandwa sub-station by power grid this month.
Tender for the study of environmental and social impact of the project area is also being issued. Madhya Pradesh Power Management Company has agreed to purchase 400 MW power from the project, he said.
The project will have floating solar panels of 600 MW power generation capacity in the backwaters of Omkareshwar dam. It is estimated that in 2 years, the project will start providing cheap and good quality power.
Electricity will be produced in about 2000-hectare water area by installing solar panels in the dam. Solar panels will float on the surface of the water in the reservoir, the release said.
When the water level of the dam is low, it will automatically adjust upwards and downwards. Strong waves and floods will have no effect on them. The sun’s rays will continue to produce electricity, it added.

Absence of study on hydrological modelling for non-dendritic catchment system has leads to difficulties in understanding the precipitation-runoff condition, designing flood risk assessment and flood mitigation action. The purposed of this study is to developed a hydrological model for Santubong River catchment and assess the possible application of Hydrological Modeling System (HEC-HMS) in estimating peak flow over non-dendritic catchment. Two types of model were created (three outlets and separated outlet)to simulate the peak flow of each model. To account the loss, runoff estimation and flow routing, initial and constant, Clark Unit Hydrograph and Muskigum methods were used respectively. After calibration and validation, separated outlet model peak discharge for O1 (44 m3/s), O2 (51.1 m3/s) and O3 (47.3 m3/s) are well fitted with the observed hydrograph compared to peak discharge in three outlets model. The result for statistical analysis showed that model performance (NSE=0.972) and the correlation (R2=0.984) for separated outlet model is appropriate for hydrological model in Santubong River catchment.

Booster and pressurization set
Irrigation and agriculture
Food and chemical industry(with stainless steel material)
The selection of 4 Inch Split Casing Water Pump mainly includes five aspects: liquid delivery capacity, unit head, liquid property, pipeline layout and operation conditions
Flow is one of the important performance data of the water pump, which is directly related to the production capacity and transportation capacity of the whole plant. Such as the design institute process design can calculate the pump normal, minimum, maximum three kinds of flow. When selecting the pump, based on the maximum flow rate, considering the normal flow rate, when there is no maximum flow rate, usually 1.1 times of the normal flow rate can be taken as the maximum flow rate.
The head required by the device system is another important performance data for pump selection. Generally, the head should be selected after enlarging 5% - 10% margin.
Liquid properties include the name of liquid medium, physical properties, chemical properties and other properties. The physical properties include temperature C, density D, viscosity u, solid particle diameter and gas content in the medium, etc., which involves the head of the system, calculation of effective cavitation allowance and suitable pump type: chemical property, mainly refers to the chemical corrosivity and toxicity of liquid medium, is the selection of pump materials and The important basis for choosing the type of shaft seal.
The pipeline layout conditions of the device system refer to the liquid feeding height, liquid feeding distance, liquid delivery direction, minimum liquid level at suction side and maximum liquid level at discharge side, as well as pipe specifications and their length, materials, pipe fittings specifications and quantities, so as to calculate comb head and check NPSH.
There are many operating conditions, such as liquid operation T, saturated steam force P, suction side pressure PS (absolute), discharge side vessel pressure PZ, altitude, ambient temperature, whether the operation is intermittent or continuous, and whether the pump position is fixed or movable.

Something we have not had to be concerned about this spring so far is the level of the Missouri River and potential flooding.
Kevin Grode with the river regulation office for the Army Corps of Engineers in Omaha says precipitation has been moderate through the region:
OC……..half their normal precipitation :21
Grode says runoff into the Missouri River system is still expected to be above normal again this year, but well contained in the reservoir system:
OC…….in 2020. :17
Above normal river releases all winter allowed the Corps to add more flood storage capacity in the upstream reservoirs.
