OMAHA, Neb. — June runoff in the Missouri River Basin above Sioux City, Iowa, was 4.1 million acre feet (MAF), 74 percent of average, according to the U.S. Army Corps of Engineers (Corps). The 2016 calendar year runoff forecast is 23.0 MAF, which is 91 percent of the historic average.
“Mountain snowpack in the reaches above Fort Peck and Garrison reservoirs peaked in early April slightly below normal and melted quickly this spring, with the bulk of the runoff entering the reservoirs during May and early June,” said Jody Farhat, chief of the Corps’ Missouri River Basin Water Management Division. “That, coupled with below normal precipitation and above normal temperatures across the upper basin, reduced inflow to the reservoir system during June.” The melting of the mountain snowpack is complete. View the mountain snowpack graphic at http://www.nwd-mr.usace.army.mil/rcc/reports/snow.pdf.
The total volume of water currently stored in the Missouri River Mainstem Reservoir System is 59.9 MAF, occupying 3.8 MAF of the 16.3 MAF flood control zone. “The reservoirs are currently occupying 23 percent of the available flood control storage and remain well positioned to capture additional runoff should reductions in releases become necessary,” said Farhat. System storage peaked at 60.1 MAF on June 22.
Based on the July 1 System storage check, the navigation service level will remain at full service for the second half of the navigation season. In addition the navigation season length will be a normal 8-month season with navigation flow support ending on December 1 at the mouth of the Missouri River near St. Louis, Mo. The September 1 system storage check will determine the winter releases from Gavins Point.
The Corps will continue to monitor basin conditions and will adjust the regulation of the reservoir system based on the most up-to-date information.
Gavins Point releases averaged 23,900 cfs during June. Releases are expected to remain near 25,000 cfs in July but will be increased if needed to meet navigation targets in reaches with commercial traffic as flows on tributaries in the lower basin recede. The reservoir behind Gavins Point Dam ended June at elevation 1206.2 feet and will remain near elevation 1206.0 feet during July.
The forecast reservoir releases and elevations discussed above are not definitive. Additional precipitation, lack of precipitation or other circumstances could cause adjustments to the reservoir release rates.


First, it is necessary to select the pump type most suitable for the application, such as centrifugal pump or positive displacement pump. Assuming that you have determined that centrifugation is the most appropriate, how do you choose a suitable model to meet the required performance?
- Conditions for centrifugal pump selection:
(1) Centrifugal pump selection: physical and chemical properties of conveying medium.
The physical and chemical properties of the conveying medium directly affect the performance, material and structure of the pump, which is an important factor to be considered in the selection of centrifugal pump. The physical and chemical properties of the medium include: medium name, medium characteristics (such as corrosivity, abrasiveness, toxicity, etc.), solid particle content, particle size, density, viscosity, vaporization pressure, etc. If necessary, the gas content in the medium shall also be listed, indicating whether the medium is easy to crystallize, etc.
(2) Centrifugal pump selection: parameters.
Parameters are the most important basis for centrifugal pump selection, which should be carefully determined according to the process flow and operation variation range.
① Flow Q. Flow refers to the medium mass required to be delivered by the pump in the production of process units. Flow is also an important factor to pay attention to in the selection of centrifugal pump. Generally, the process personnel shall give the normal, minimum and maximum flow. Only normal and rated flow are often given on the pump data sheet. During the selection of centrifugal pump, the rated flow shall not be less than the maximum flow of the device, or 1.1 ~ 1.15 times of the normal flow.
② Lift H. Head refers to the head value required by the process unit, also known as calculated head. General centrifugal pump selection requires that the rated head of the pump is 1.05 ~ 1.1 times of the head required by the device.
③ Inlet pressure P and outlet pressure P. The outlet pressure refers to the pressure at the inlet and outlet connecting pipe flange of the pump. The inlet and outlet pressure affects the pressure resistance of the shell and the requirements of the shaft seal.
④ Temperature T. Temperature refers to the inlet medium temperature of the pump. Generally, the normal, minimum and maximum temperatures of the inlet medium of the pump in the process shall be given for the selection of centrifugal pump.
⑤ Npsha of the unit is also called effective npsha.
⑥ Operation status. The operation state is divided into continuous operation and intermittent operation.
(3) Centrifugal pump selection: site conditions.
The site conditions include the installation location of the pump (indoor and outdoor), ambient temperature, relative humidity, atmospheric pressure, atmospheric corrosion status, classification of hazardous areas, etc.
- Selection of materials for centrifugal pump selection:
Centrifugal pump series refers to the pumps with the same structure and purpose produced by the pump factory, such as is clean water pump, S-type double suction centrifugal pump, IH chemical pump, ZGB slurry pump, etc. Through the comparison of different materials to judge how to select the centrifugal pump. In the selection of centrifugal pump, the series and materials of the pump are selected according to the process parameters and medium characteristics.
(1) According to the characteristics of the medium, decide which characteristic pump to choose, such as clean water pump, corrosion-resistant pump and impurity pump. When the medium is highly toxic, valuable or radioactive and other substances that are not allowed to leak, consider selecting non leakage pump (such as shielded pump and magnetic pump) or double face mechanical seal with leakage liquid collection and leakage alarm device. If the medium is volatile liquid such as liquefied hydrocarbon, select low cavitation allowance pump, such as cylindrical pump.
(2) Horizontal centrifugal pump and vertical centrifugal pump (including submerged sewage pump and pipeline sewage pump) shall be selected according to the on-site installation conditions.
(3) Single stage single suction centrifugal pump, double suction centrifugal pump or small flow centrifugal pump shall be selected according to the flow of the water pump.
(4) Single stage centrifugal pump, multi-stage centrifugal pump or high-speed centrifugal pump shall be selected according to the pump head.
Finally, according to the characteristics of the device and the parameters of the pump, decide which kind of manufacturing and inspection standard to choose.

Free Flow Power Corp. (FFP) is seeking a license from the Federal Energy Regulatory Commission (FERC) to develop a hydroelectric project at the Enid Dam on the Yocona River in Yalobusha County, Miss.
The application was filed June 25 at FERC for the Enid Lake Hydroelectric Project by FFP Missouri 2 LLC, a domestic limited-liability company for which Free Flow Power is authorized to act as an agent.
The project will utilize the existing dam owned and operated by the U.S. Army Corps of Engineers (USACE), and operate in a run‐of‐release mode. FFP was issued a three-year preliminary permit for this project by FERC in December 2010.
The project site is about 6.5 miles north of the town of Oakland, Miss., and will involve the construction of a new 4.6-MW facility. The primary purpose of the existing USACE facility is for flood control and the facility also provides recreational opportunities for the public.
A new concrete powerhouse will be built on the north bank, downstream of the existing stilling basin adjacent to the river channel and contain two identical turbine-generator units with a combined installed capacity of 4,600 kW. Two new identical vertical Kaplan turbines will be installed in the powerhouse.
The project will have an installed capacity of 4.6 MW, an average annual energy production of 17.7 gigawatt hours (GWh) and an average monthly energy production of 1.46 GWh.
A new substation will be constructed about 550 feet west-northwest of the existing outlet works at the toe of the dam. Project output will be transmitted from the powerhouse to the new substation via a buried medium voltage cable. A new overhead transmission line will extend west from the substation to an interconnection point at the utility owned distribution line.

The Kaunas Reservoir was formed during construction of the Kaunas Hydroelectric Plant (Kaunas HP) on the Nemunas River in 1960. Since 1992 it has also been serving as a lower reservoir for the Kruonis Hydroelectric Pumped-Storage Plant (Kruonis HPP), which currently has four generating units with 200 MW of installed capacity each. There are plans to increase the capacity of this power plant by constructing additional four generating units. Operation of the Kruonis HPP is already changing the hydrophysical regime (water levels and flow velocities) of the Kaunas Reservoir and new units can seriously aggravate the situation by inducing bottom erosion. The objective of this study is to determine the optimal number of generating units so that the impact of the Kruonis HPP on the hydrophysical regime of the reservoir would be acceptable. The hydrodynamic model MIKE 21 was used to calculate the flow velocity and water level fluctuation in the Kaunas reservoir for different number of the Kruonis HPP generating units. The Kaunas HP was considered as operating with minimal load or under conditions equivalent to a big flood (2,000 m3/s). The modelling results indicate that the impact of four units is acceptable while simultaneous operation of the eight units at Kruonis HPP would not be desirable.

The iSAM model is a large-scale, 2D TELEMAC tidal flow model developed at IMDC. The model includes Eastern Indian Ocean, Western Pacific Ocean, as well as the Southeast Asian and Northern Australian waters in between. In addition to tidal forcing, the model can be also imposed with meteorological forces consisting of wind and air pressure fields for running in either operational forecast or hindcast mode.
The iSAM model can be used to generate boundary conditions for more refined project specific models, which can be adjusted according to the clients requirements. The more refined models allow detailed assessment of local hydrodynamics, sediment transport and medium to long term morphological changes.

Abstract or Description
The dams in the Belgrade Lakes Region of central Maine control water flow of the six main ponds in the watershed. This project simulated historical water levels of these ponds and analyzed what surface area of land maybe have been exposed before the dams were constructed. Our simulation resulted in a 57.7% decrease in surface area of the ponds compared to current surface area. However, it is likely that the change we found is an overestimate because we used dam hydraulic height to calculate the change in water level instead of the actual water height.

Pressure gauges are an integral part of controlling both static and dynamic wellhead pressure.
Static wellhead pressure is gauged in abandoned wells and depends on reservoir pressure, well depth, and density of the filling medium. Numerically it is equal to the difference between the reservoir pressure and hydrostatic pressure of the liquid column from wellhead to reservoir.
Dynamic wellhead pressure is measured in an operating well and depends on the same parameters as the static pressure, as well as the well rate or injection agent flow rate. It also depends on the pressure in the pipeline near the well, and on the pressure differential in the shut-off elements of the wellhead fittings.


Mackay Council will begin work on upgrading Middle Creek Dam to meet new flood requirements set out by the Queensland Dam Safety Regulator. Entracon Civil Pty Ltd has been awarded the $998,000 contract for phase one of the two-phase project.
Phase one will see the spillway crest lowered by about one metre and the dam wall raised by about half-a-metre.
Once phase one is complete, the dam will be equipped to withstand flood events significantly worse than the 2008 Mackay floods.
Before work begins, the dam level will be reduced to create a storage buffer against any unseasonal rainfall impacts.
During construction there will be some minor noise and traffic disruptions in the area.
Council will be engaging with nearby residents and traffic management will be in place to minimise disruptions.
Phase one is expected to be completed this year before the onset of the wet season.
Phase two of the works is required to be undertaken by 2035 and will involve the installation of a more efficient spillway to further improve capacity and the dam wall raised by another 60 to 70 centimetres.


FORT ST JOHN: BC Hydro reached a new milestone on the Site C project with substantial completion of excavations in the Peace River diversion tunnels on December 24, 2019.
The two large diversion tunnels, located on the north bank of the river, are approximately 750 metres long and 11 metres in diameter. Beginning later this year, they will be used to reroute the Peace River around the dam site, allowing for the construction of the earthfill dam across the main river channel.
A look inside one of the fully excavated diversion tunnels, temporarily lined with shotcrete.
Excavations on the two tunnels began in summer 2018 and breakthrough on the upper half of the tunnels (known as the “crown”) occurred in summer 2019. Since that time, efforts focused on excavating the lower half of the tunnels (known as the “bench”).
The concrete tunnel lining process is, on average, about 50 per cent complete in the tunnels. This involves using a custom-built slip form which enables concrete to cure in a perfect circle outside the form. At the same time, construction of the structures that will house the inlet gates are nearing completion; construction of the outlet gate structures will be completed once the concrete lining forms have been removed from the tunnels.
Workers walk through a segment of one of the diversion tunnels, recently lined with concrete.
BC Hydro remains on schedule to begin diverting the Peace River in September 2020. River diversion will be in place until the Site C reservoir is filled in 2023.


The function of the check valve is to only allow the medium to flow in one direction and prevent the flow in the opposite direction. Usually this kind of valve works automatically. Under the action of the fluid pressure flowing in one direction, the valve flap opens; when the fluid flows in the opposite direction, the fluid pressure and the self-coincidence of the valve flap act on the valve seat, thereby cutting off the flow.
Common failures of check valves include:
①The valve disc is broken;
②The medium flows back.
1. The reason for the disc breaking is: the pressure of the medium before and after the check valve is close to equilibrium and they are in a state of "seeing" each other. The disc often beats against the valve seat, and some brittle materials (such as cast iron, brass) are made of The finished valve disc was broken. The preventive method is to use a non-return check valve whose disc is a flexible material.
2. The reasons for the backflow of the medium are:
①The sealing surface is damaged;
② Clamp in impurities.
Repairing the sealing surface and cleaning impurities can prevent backflow.
A check valve is a valve that automatically opens and closes the disc depending on the flow of the medium itself, and is used to prevent the medium from flowing back. It is also called a check valve, a one-way valve, a reverse flow valve, and a back pressure valve. Its main function is to prevent the medium from flowing backwards, to prevent the pump and drive motor from reversing, and to discharge the container medium. Check valves can also be used to supply pipelines for auxiliary systems where the pressure may rise above the system pressure.


Phalen and Keller Weir Projects
The Phalen Lake outlets and Keller Channel weirs are getting an upgrade as part of the Beltline Resiliency Plan.
RWMWD will be able to automatically adjust the weir heights on the Keller Channel structure and the Phalen Lake outlet structure when the project is completed this spring. The remote weir adjustments mean RWMWD can set the water level for the Phalen Chain of lakes when it rises above normal or in anticipation of sizeable rain events. This capability will help prevent flooding during abnormally large rain events and allow for additional water storage farther up the Phalen Lake Chain.
The construction team will be onsite through March 31. Residents and park users can expect temporary alternate walking paths around the project area during construction.

This project involved the Installation of a new pump pit for Swope Park Pool. The work included site excavation for the underground pool pump pit. The pit was constructed of cast-in-place thickened slab/foundation, walls and structural deck. Underground PVC piping was installed to route the pool lines through the new pump pit. The existing pumps were removed from the existing above ground pump room and installed in the new pump pit. Project also included a new pool filtration system, electrical, controls, and site improvements.
The project included the relocation and reuse of key components of the pool.


Franson Civil was hired by the Utah Division of Water Resources (Utah DWRe) to perform structural design of the spillway and design the relocation of the outlet works for the rehabilitation of the dam and spillway at Millsite Reservoir, located in Ferron, Utah. The outlet works needed to be extended further downstream to allow for the rehabilitation of the dam. All drawings and specifications were prepared to meet Utah Dam Safety and Natural Resource Conservation Service (NRCS) standards.
There are several aspects of this elaborate and substantial multi-year project that have required excellent service. First, Franson completed the project design phase. Franson assisted with the design of the spillway and outlet works improvements and provided drafting services for the entire dam rehabilitation project. Another contribution to the project included providing expertise in specific areas and reviewing the Utah DWRe design for constructability.
Specific project features designed by Franson Civil include:
- Extending the existing outlet tunnel and the existing 54-inch main outlet pipe
- Extending all appurtenances necessary for operation of the outlet works such as electrical wiring, air vent shaft, tunnel drains, etc.
- Replacing the existing 42-inch Howell Bunger valve with a new plunger valve and the existing 8-inch culinary pipeline with a new culinary pipeline
- Relocating or replacing the connections for two 36-inch irrigation pipelines, one 12-inch stockwater pipeline, and one 24-inch industrial water supply pipeline
- Designing improvements to the state park to eliminate the impacts of the raised reservoir
- Structural design of the enlarged concrete spillway
Franson Civil has also provided full-time construction observation and management services. This large project has necessitated extensive communication and coordination between the client, the engineering team, the contractors, and other regulatory agencies. Rehabilitation construction is scheduled to conclude in mid-2022.

Uzbekistan to build two small hydroelectric plants in 2011
Uzbekistan, Tashkent, Sept. 4 / Trend D.Azizov /
The State Joint-Stock Company Uzbekenergo plans to begin construction of two small hydroelectric plants (HPS) with a total capacity of 120 megawatts in the Surkhandar region in south Uzbekistan in early 2011, the company has told Trend.
The planned capacity of the Zarchob HPS on the Tupalangdarya River will be 90 megawatts while the capacity of the Nilo-II HPS on the Sangardakdarya River is planned to be 30 megawatts.
The stations will be built using the "non-dam principle" to exploit the natural flow of the rivers without the need to build dams and canals to generate power.
It is expected that feasibility studies for the projects will be complete by late 2010.
According to preliminary calculations, the total construction cost of the plants will be about $149 million, with the Zarchob HPS costing about $116 million and the Nilo-II HPS costing about $33 million. The project will be financed Uzbekenergo, the Fund for Reconstruction and Development of Uzbekistan and Uzbek banks.
The HPSs are expected to be commissioned in 2013.
Uzbekistan plans to build nine small hydroelectric plants at a cost of $255.7 million between 2010 and 2014. Uzbekenergo's plan is based on small- and medium-sized hydroelectric plants with a total capacity of 323.6 megawatts, to be built on the country's natural watercourses, to increase the share of renewable energy in the country's energy needs.
The company has also established four large hydroelectric plants with a total capacity of 203.6 megawatts. The preliminary estimated cost of the plants is $227.8 million in the Tashkent region and $148.9 million in the Surkhandar province.
The country also plans to construct a small Camelot Hydropower Plant under the Chirchik-Bozsu Tract, worth about $11.3 million with an annual design capacity of eight megawatts by late 2012. The plant will allow 35 million kilowatt-hours of electricity to be produced per year, which is equal to fuel savings of 11 million cubic meters of natural gas per year. Uzbekenergo will invest $3.3 million from its own funds in the construction of the plant and $8 million from loans.
Uzbekistan has dozens of reservoirs, irrigation canals and mountain rivers where the country can build 141 power plants, experts say, with a total capacity of 1.180 megawatts and annual power generation of 4.6 billion kilowatt-hours.
To date, the country has put into operation seven stations with a total capacity of 200 megawatts. There are 42 power plants with a total capacity of 12.358 million megawatts in the power generation system. Uzbekenergo's 10 thermal power plants with an installed capacity of 10.6 million kilowatt-hours produce 90 percent of the total volume.
Uzbekistan decreased power production last year by 0.3 percent to 49.954 billion kilowatt-hours compared to 2007. From January to June 2010, power production increased by 3.1 percent to 25.945 billion kilowatt-hours compared to the same period in 2009.

Delay in bridge construction hits hydel projects
Lamjung, August 3
Eight years have passed since the construction of a motorable bridge over Dordikhola started in Lamjung. However, the delay in construction of the bridge has affected the work of under construction hydro projects and local people’s movement.
Upper Dordi A (25 megawatt), Super Dordi Kha (54) Dordikhola Project (27) and Dordi A (12) are under construction in Dordikhola. Soaring water level in Dordikhola makes it hard to supply construction materials for hydro projects in the rainy season.
Road Division Office, Damauli, had awarded the contract for constructing the bridge to Sapana Construction Service Company and Jaya Baba Company some eight years ago.
As per the agreement, the bridge was supposed to be completed in two years. Despite repeated extension of the deadline, only eighty per cent work has been completed so far, said Gautam Shrestha, an engineer at Division Office, Damauli.
Hume pipes were laid in the river to enable vehicles to supply construction materials in winter. “The supply of the construction materials is halted in the rainy season,” said project director Arjun Gautam at People Hydro Power Company, which is constructing Dordi KHA hydro project. Gautam said the delay in construction of the bridge had added financial burden on hydro projects.
Delay in the bridge construction has hit not only hydro projects but also local people. Dordi Rural Municipality Chair Om Bahadur Gurung said locals were forced to cross the khola risking their lives for want of bridge during monsoon.

Description for Plaine Hollandaise Dam ( Seychelles )
The project is aimed at increasing the drinking water resource of Praslin island (the second most important island in the Seychelles archipelago) and at balancing the existing pipeline network scheme.
SP, in recent years, has consolidated its presence in the main islands of the Indian Ocean (i.e. Seychelles, Mauritius etc.), in the field of design and supervision of dams, Water Treatment Plants and Water Supplies. As far as the Seychelles archipelago is concerned, SP is currently involved in the design of the Plaine Hollandaise dam and the Grand Anse dam and as an Engineering Company in the raising of the La Gogue dam.
To optimize the use of existing resources and to improve the water supply, the Public Utilities Corporation (PUC) has implemented the Seychelles Water Development Plan 2008-2030 (SWDP). The Master Plan shows the necessity for providing sufficient water storage on Praslin Island. In this framework, the SP project of a new reservoir in Plaine Hollandaise takes place, a flat area in the centre of Praslin Island.
The design of the dam will guarantee water supply to the two administrative districts of the island: Baie Sainte Anne and Grand Anse, respectively located in the east and in the west of the island. The water of the Plaine Hollandaise reservoir will be transferred, after water treatment, into the existing network of Pasquières and Grande Anse

Modelling Water Flow in Unsaturated Porous Media: Accounting for Nonlinear Permeability and Material Heterogeneity
The book focuses on two issues related to mathematical and numerical modelling of flow in unsaturated porous media. In the first part numerical solution of the governing equations is discussed, with particular emphasis on the spatial discretization of highly nonlinear permeability coefficient. The second part deals with large scale flow in heterogeneous porous media of binary structure. Upscaled models are developed and it is shown that the presence of material heterogeneities may give rise to additional non-equilibrium terms in the governing equations or to hysteresis in the averaged constitutive relationships.

Hirakud Dam Project is a multipurpose scheme intended for flood control, irrigation and power generation. The dam is built across river Mahanadi at about 15 km upstream of Sambalpur town in the state of Odisha. This is one of the oldest hydel projects of India, being the first post-independence major multi purpose river valley project in the country. Pandit Jawaharlal Nehru laid the foundation stone in 1948. The dam is located at a distance of 6 km from national High way no. 6. The nearest rail head is Hirakud Railway Station which is at a distance of 8 km from the dam site.
The project provides 1,55,635 hectares of Kharif and 1,08,385 ha of Rabi irrigation in the districts of Sambalpur, Bargarh, Bolangir and Subarnapur. The water released through the power house irrigates further 4,36,000 ha of C.C.A in Mahanadi Delta. The installed capacity for power generation is 359.8 MW through its two power houses at Burla, at the right bank and Chiplima, at 22 km down stream of Dam. Besides, the project provides flood protection to 9500 sq. km of delta area in districts of Cuttack and Puri.


In order to study the energy characteristics and internal flow field of “S” shaped airfoil bidirectional axial flow pumps, the SST k
turbulence model is used to calculate the bidirectional axial flow pump, and the experimental verification is carried out. The results show that the error of numerical calculation of forward and reverse operation is within 5%, and the numerical calculation result is credible. The test results show that the bidirectional axial flow pump has a design flow rate of Q
= 368 L/s, head H
= 3.767 m, and an efficiency of η
= 80.37%. In reverse operation, the flow of the bidirectional axial flow pump under design condition Q
= 316 L/s, head H
= 3.658 m, efficiency η
= 70.37%. The flow of forward operation is about 15% larger than that of reverse operation under design working condition, the design head is about 3.70 m, and the efficiency of design working condition is about 10% higher than that of reverse operation. The numerical calculation results show that under the forward design condition (Q
= 368 L/s), the hydraulic loss accounts for 6.22%, and under the reverse design condition (Q
= 316 L/s), the hydraulic loss accounts for 11.81%, with a difference of about 6%. The uniformity of impeller inlet flow rate under the forward operation is about 12% higher than that in the reverse operation. In forward and reverse operation, with the increase of flow, the outlet streamline, the outlet total pressure distribution, the uniformity of impeller inlet velocity, and the vortex in the impeller domain are improved, and the forward direction is better than the reverse direction. The research results of this paper can provide a reference for the research and optimal design of the bidirectional axial flow pump.

Kollam: The check dam across Pallikkalar river at Thodiyoor here has proved to be a curse for the paddy farmers at Pavumba and Thazhava as well as the residents in the adjacent low-lying areas.
The unscientific construction of the check dam hinders the flow of water, which has not yet been rectified even after several protests. The fields and roads often get inundated as the channel through the check dam is insufficient to carry the gush during the rain.
The check dam was constructed for Aryanpadam lift irrigation project at Thodiyoor in 2014.
It has a total length of 30 metres and has three openings with a width of 3.5 metres, which is insufficient to carry the outflow of water.
The farmers of Churuli padasekhara samiti had earlier protested alleging the construction of check dam was unscientific. Several paddy fields, including Churuli, Kuttathukuzhi, Manappalli, and Perakka vayal, were inundated even during light rain after the construction of the check dam.
An expert team had pointed out the flaws with the check dam that caused flooding in Pavumba area.
The removal of the sedimentation of rocks and sand under Thodiyoor Kochupalam bridge has been insufficient to rectify the situation.
The Pallikkal river originates from Kodumon in Pathanamthitta and ends at Kannetti lake at Karunagappally spanning over 42 km....

Mississippi River Reaches Flood Stage
The Mississippi River has reached flood stage in the Quad Cities, and will go up some more. But not as much as some recent forecasts had suggested.
Monday at midday, at Lock and Dam 15, the river was at flood stage, and is expected to rise half a foot higher, and crest on Thursday. It should then hold at that level through early next week.
As recently as Friday, the forecast had been for a crest one foot over flood stage.
In Dubuque on Monday, the Mississippi is eight-tenths of a foot below flood stage, and it should hold near that level for a week.
Minor flooding is occurring along the Rock River at Joslin. The river crested Sunday about two-tenths of a foot over flood stage, and has since begun to fall slowly.
The level at Moline is still half a foot below flood stage, and it's expected to drop very slowly during the coming week.

Hydraulic Pneumatic Seals
Hydraulic Pneumatic Seals we offer are designed for the reciprocating movement that is common in hydraulic as well as pneumatic applications. These are made for high-pressure dynamic applications such as hydraulic cylinders. These seals are applicable in pneumatic cylinders, valves and generally made for lower operating pressures. These demand higher operating speeds and may be employed for rotary as well as reciprocating motion. Hydraulic Pneumatic Seals are used in applications with axial movement, such as cylinders and pistons. The action of these Hydraulic Pneumatic Seals can be single or double. These are employed to make a seal between the piston as well as the cylinder bore, precluding leakage of hydraulic liquid or air.
