Under the "dual carbon" goal, the establishment of a high proportion of renewable energy power system is an important means. At present, the integrated development of renewable energy in river basins, which is dominated by water and scenery, is the only way for the high-quality development of renewable energy in the new era. Under the new situation, hydropower development requires that while providing electricity, it is necessary to provide more capacity for the power system as much as possible, undertake more system peak regulation and frequency regulation tasks, and provide guarantee and support for the consumption of new energy such as wind power and photovoltaics. Sichuan Province needs to build a new power system with a gradually increasing proportion of new energy, and it is necessary to build more flexible power sources. The use of conventional hydropower dams and reservoirs built in major river basins and appropriate expansion can better meet the capacity and peak shaving needs of the future power system.
The main stream of the Dadu River is one of the important hydropower bases in China, with 28 levels of hydropower planning, with an installed capacity of 27 million kilowatts, and 20 are currently under construction, with a total installed capacity of 22.8 million kilowatts. The main stream of the Dadu River has many high dams and reservoirs, with good regulation performance, strong peak regulation capacity and relatively good construction conditions. After preliminary research, the expansion capacity potential of the Dadu River main stream cascade power station exceeds 12 million kilowatts.

One of land use change impacts in the downstream of Citarum watershed is sedimentation. This study aimed to determine the total suspended solid and sediment load in the downstream of Citarum River. The Total Suspended Solid (TSS) samples were taken in three locations: the inlet of Jatiluhur reservoir, the outlet of Jatiluhur reservoir, and before the Citarum River estuary. The frequency of TSS samplings was twice a year i.e during the dry season and the rainy season at 2014. Analysis of TSS content was in accordance with SNI 06-6989.3-2004 using gravimetry method. The results showed that TSS at down stream Citarum River flow was 0.44 kg/m3, TSS at the inlet of Jatiluhur reservoir was 0.20 kg/m3, and TSS at the outlet of Jatiluhur reservoir was 0.02kg/m3. The total sediment in the inlet of Jatiluhur was 1.34 x 106ton/year, in the outlet of Jatiluhur reservoir was 0.14 x 106ton/year, and the flow sediment total to the Citarum River estuary was 1.79 x 106 ton/year. The Jatiluhur reservoir could reduce the potential for sediment total flowing into the sea as much as 1.20x 106tons/year. Area of sedimentation at the delta of Citarum River was 3,828.26 ha.

High Profile Irish Water Project - Ballycoolen
Posted on 05th Nov 2021
Viking Johnson have recently supplied product to a high profile project in Ballycoolen, Ireland.
Working with Irish Water, a large quantity of DN900 and DN1200 dedicated flange adaptors, couplings and dismantling joints were supplied. Roadbridge, the main contractor and a large Irish owned civil engineering company, have been installing these fittings from June 2021.
The project consists of a new trunk water main to serve parts of Dublin North City and North County Dublin, benefiting residents, businesses, hospitals and agriculture. It includes the construction of a 1200mm diameter trunk main from the Ballycoolen Reservoir site to Forrest Little to duplicate the existing 900mm diameter trunk main, a total length of approximately 10km.
The existing water supply network depends on a single large diameter concrete water main built in the 1960’s. It is operating beyond its capacity, which results in low water pressure across the region during periods of peak demand. The new additional trunk water main will improve the security of supply and resilience of the network, enabling long-term social and economic development in North Dublin and ensure that water pressures are maximised.
The works are due to commence in Q2 2021 and it will take two years for completion of the project.

How many tourists visit the Three Gorges Dam each year?
1.8 million tourists
The dam’s scenic area, which spans the middle reaches of the Yangtze River in Yichang, Hubei province, covering 15 sq km, is a popular tourist destination attracting an average of 1.8 million tourists per year. The dam has received 15 million visitors since completion in 2006, Xinhua reported.
How does the Three Gorges Dam affect tourism?
The number of tourists visiting the city increased by 21.6 percent in the first half of last year, bringing in revenue of nearly 23 billion yuan (3.5 billion US dollars), up by more than a third.
How many people does the Three Gorges Dam give power to?
The project has 34 generators, which includes 32 main generators. The other two are power generators with a capacity of 50MW each. The plant took 17 years to construct and was built in stages by state-backed sponsor China Yangtze Three Gorges Dam Project Development Corporation. Initial works began in 1993.
Is Three Gorges Dam complete?
The dam body was completed in 2006. The power plant of the dam project was completed and fully functional as of July 4, 2012, when the last of the main water turbines in the underground plant began production. Each main water turbine has a capacity of 700 MW.
Is the Three Gorges Dam a good place to visit?
The area is nicely landscaped with dancing fountains and a good elevated viewing area. My wife and I visited the tourist area at The Three Gorges Dam In October 2018 as part of a two week tour of China. The dam is huge HUGE. The tourist area is on the dam site, and has architecture, fountains and several viewing areas.
When did the Three Gorges Dam project start?
Three Gorges Dam is 2,308m in length and 185m in height, and the project started from December 14th, 1994, and it’s completed and fully functional as of July 4th, 2012 (except for a ship lift, which was completed in December 2015).
How big is the reservoir at Three Gorges?
Flood Control Benefit: when the reservoir of Three Gorges Dam operates, the reserved flood control capacity is 22.15bn cubic meters, and the peak discharge of flood can reach to 27,000 ~ 33,000 m3/s.
How long does it take to pass Three Gorges Dam?
Besides, that is the final construction item of the Three Gorges project. Ships now need only about 40 minutes now to pass the dam by the ship lift, compared to passing the ship locks, which makes great contribution for the efficiency of ships passing through the Three Gorges Dam.

Pumped storage hydroelectricity has been around for more than 100 years. An alternative to battery storage, pumped storage stores and generates energy by moving water between two reservoirs at different elevations. Water is pumped from the lower reservoir to the upper reservoir at night when electricity demand is low and rates are less expensive. During periods of high electricity demand, water from the upper reservoir is released into the lower reservoir. Water flows through turbines at the base of the lower reservoir, generating electricity.
Pumped storage can be used to store solar or wind power, it can balance sudden changes in demand, and it offers far greater storage capacity than batteries. While there are some disadvantages to pumped storage — it demands a large upfront capital investment, finding an appropriate site is difficult, and such systems may use more energy to pump the water uphill than they produce — it is considered one of the most economical options for large-scale energy storage, accounting for more than 99 percent of bulk storage capacity worldwide.

The U.S. Army Corps of Engineers Jacksonville District will reduce flows from Lake Okeechobee to help offset impacts to the saltwater-freshwater mix to the St. Lucie Estuary. The adjustment in discharges will take place tomorrow (March 20). The new target flow for the St. Lucie Estuary will be a seven-day average of 730 cfs as measured at St. Lucie Lock & Dam (S-80) near Stuart. The target flow for the Caloosahatchee Estuary is unchanged at a seven-day average of 2,500 cubic feet per second (cfs) as measured W.P. Franklin Lock (S-79) near Fort Myers.


by Samuel Aubrey Borneo Post March 12, 2012KUCHING: The impoundment of the Bakun Dam reservoir, which commenced on October 13, 2010, has reached the full supply level of 228m above sea level (asl) as of last Friday.
Sarawak Hidro Sdn Bhd (SHSB) managing director Zulkifle Osman said the size of the reservoir was now over 695 square kilometres, which is a water body equivalent to the size of Singapore.
Despite this, he said based on SHSB’s spillway operation rule, the reservoir would have to be lowered six metres to eight metres below the full supply level.
It has to be maintained at this level until such time the Sarawak Electricity Supply System load increases to allow the reservoir to operate over its full range, he added.
The additional release for reservoir lowering is scheduled to commence today.
“The lowering of the reservoir level also serves as an important purpose in providing flood storage of the reservoir, and hence reducing the peak spillway discharges during floods, thereby regulating floods downstream,” he said in a statement.
He also mentioned that since November 11 last year, Bakun Dam has been continuously releasing about 500 cubic metres per second (m3/s) of water through its spillway, and up to 300 m3/s from the powerhouse for power generation to enable unrestricted river traffic, especially for passenger express boats travelling between Kapit, Belaga and Bakun.
As for today’s scheduled reservoir lowering, he said the total discharge downstream would be three times more, at 2,500 m3/s.
“This is approximately 1.6 times the long term average flow of Batang Balui (1,500 m3/s), but much lower than high flow of the river. It is anticipated that with this additional discharge, the downstream river level will rise further, and the river flow will become swifter.
“As such, river users and inhabitants downstream of the dam are hereby advised to take extra precautions on the rising river level and fluctuating river flows.”
He also said SHSB, as owners of Bakun Dam, wish to express their sincere appreciation to the downstream folks for their understanding and cooperation during the impoundment period.
“The downstream river users have benefitted from almost uninterrupted river travel.”

A new numerical simulation of single well reservoir model with fractal concept has been successfully developed in this study. The mathematical equations in which fractal dimension is explicity included have been formulated numerically for the radial three-phase flow (oil, gas and water) using a cylindrical coordinate system. By these new formulations, a radial multiphase flow in naturally fracture reservoir was modeled by assuming that all storage capacity in the rock system is merely due to fractures. The formulations of this model were then solved numerically by implementing the IMPES solution technique.
The model developed had been validated with the analytical model of single phase flow in radial system developed by Aprilian (SPE # 26465, 1993). In all cases, comparisons of these two models had shown similar results.
Using this new model, reservoir performance prediction of single well reservoir models had been performed with various cases and fractal dimensions. In this particular cases, the resulting performances of several hypothetical reservoirs with various fractal dimensions were then correlated to generate new type curve models. These type curves can be used for estimating fractal dimension of a reservoir.

KATHMANDU, July 26: A tripartite memorandum of understanding (MoU) has been signed for loan investment in the 99.8 MW Tamakoshi-V Hydropower Project to be constructed in Dolakha.
The MoU was signed among Nepal Electricity Authority, Tamakoshi Hydropower Company, the promoter of the project, and Employees Provident Fund (EPF) in the presence of Minister for Energy, Water Resources and Irrigation Pampha Bhusal on Sunday.
The project is expected to materialize an investment of Rs 16.19 billion (USD 137.2 million), in which EPF will invest 70 percent (about Rs 11.33 billion) as loan. The remaining amount of the project being constructed under the People's Hydropower Program will be raised from equity by issuing shares to the general public.
Tamakoshi-V is the fifth 456 MW Upper Tamakoshi Cascade Project. Therefore, the project is considered attractive as there is no need to build structures like dams and sand thawing ponds (descender). The gate required to send the water from the Upper Tamakoshi power house to the project tunnel has been installed. The project will have to construct an 8 km tunnel, power house, about 2 km 220 kV transmission line and other main structures.
The project, which has received detailed design and environmental impact assessment (EIA) approval, has already received permission to generate electricity in 2017. Further environmental studies of the project have been carried out with the grant of the Asian Infrastructure Investment Bank (AIIB) established under the leadership of China. Pre-construction works of the project are underway now. The construction work has been expedited with the aim of completing the construction of the project by 2028.

On May 15, 2006, Chinese news media reported that engineers were pouring the last of the concrete to finish the construction of the massive Three Gorges Dam on the Yangtze River in central China. The dam is intended to provide flood control and hydroelectric power. When all the generators are operational (projected for 2009), Three Gorges will become the largest hydroelectric project in the world.
This pair of images shows the dam in partial completion in July 2000 and again in May 2006. The Yangtze River flows from upper left toward upper right in the images. In 2000, construction along each riverbank had occurred, but sediment-filled water still flowed freely through a narrow channel near the river’s south bank (bottom left). A smaller passage closer to the north bank of the river, where the water appears calmer, is likely a system of temporary locks that allowed for boat passage. A second dam bypass appears to be under construction about 1 kilometer to the north.
By May 15, 2006, the dam spanned the entire river, and a large reservoir had filled behind it, to the northwest. The new reservoir is more than 3 kilometers (more than 2 miles) across just upstream of the dam. White spray shoots through gates in the center portion of the dam. The former locks are much less prominent, and the new ones to the north appear as a linear arrangement of thin, blue rectangles.
May 20, 2000, image centered on the Wu Gorge, the middle of the three gorges that will be affected by the Three Gorges Dam Reservoir.
The longest river in Asia, the Yangtze River brings mixed blessings to China. Although it meets the water needs of millions of people, the river regularly overflows its banks. To protect residents and land in the lower Yangtze floodplains, China began construction on the Three Gorges Dam in 1994.

According to data I found on the USGS website, the water level in Cross Lake in Shreveport is only at 170.22, which is the lowest the water level has been in years. The water level is typically at 173. Where is all the water going? Are the gas companies using the water from Cross Lake to pump into their wells?
With the water level getting so low gives us even more need to have the lake dredged. Are there any plans in the near term to complete the proposed $80 Million project?

Self-priming pumps are divided into the following categories based on the principle of action: 1. Gas-liquid mixing (including internal mixing and external mixing); 2. Water ring wheeled; 3. Jet (including liquid jets and gas jets). The working process of the gas-liquid hybrid self-priming pump: due to the special structure of the self-priming pump body, after the pump stops, a certain amount of water is stored in the pump body. After the pump is started again, the air and water in the suction pipeline are sucked due to the rotation of the impeller. Fully mixed and discharged to the air-water separation chamber. The gas in the upper part of the air-water separation chamber overflows. The lower part of the water returns to the impeller and mixes with the remaining air in the suction pipeline until the gas in the pump and the suction tube is completely discharged. Suction, and normal pumping. The water ring wheel type self-priming pump combines the water ring wheel and the water pump impeller in a shell and discharges the gas through the water ring wheel to achieve self-priming. When the pump works normally, the passage of the water ring wheel and the pump impeller can be cut off by the valve and the liquid in the water ring wheel can be drained. Jet self-priming pump, which is a combination of a centrifugal pump and a jet pump (or ejector), relying on a spray device to create a vacuum at the nozzle to achieve suction.
According to the pump's supporting power machine type, it is divided into a motor supporting self-priming pump and a diesel engine supporting self-priming pump.
According to the structure and working characteristics of achieving self-priming function, it can be divided into inner slide type, outer slide type, water ring type and other types. There are direct drive (including inner shaft) and belt drive. Imported diameter 25 to 200 mm.
The operating principle of the external mixing self-priming pump is that the pump is filled with water (or the pump housing itself contains water) before the pump starts. After starting, the impeller rotates at a high speed so that the water in the impeller channel flows toward the volute. At this time, the inlet forms a vacuum, so that the inlet reverse door is opened, the air in the suction pipe enters the pump, and reaches the outer edge through the impeller channel. On the other hand, the water discharged from the impeller into the air-water separation chamber flows back through the left and right water-return holes to the outer edge of the impeller. The water flowing back from the left backwater hole is directed into the impeller channel under the influence of pressure difference and gravity, and is broken by the impeller. After being mixed with the air from the suction pipeline, the water is thrown toward the volute and flows in the direction of rotation.
Internal mixing type self-priming pump works in the same principle as the external mixing self-priming pump.
Most of the self-priming pump is matched with the internal combustion engine, and it is mounted on a movable trolley and is suitable for field operations.

A simulation approach in estimating the impact of channel on port capacity
This paper addresses the impact of channel waterways on the overall port capacity. In particular, we proposed a definition and two performance measures that can be used to quantify this impact. We then developed a simulation model to simulate the channel activities for estimating the impact of channel under different operating conditions. The simulation results show that when port efficiency level increases, the channels will reduce the overall performance of the port, and thus become a bottleneck in the system.
