Now hydropower can work as a energy gain, that is if the water naturally comes up to the reserve via rainwater, streams etc. etc. But pumping water back up is only done to make the plant work
The today's world wide yearly loss of storage capacity due to sedimentation is already higher than the increase of capacity by the construction of new reservoirs for irrigation, drinking water and hydropower. For long-term the reservoir operates only at reduced functional efficiency.
Three general strategies for addressing reservoir sedimentation currently utilized are: reduction of incoming sediments, minimization of sediment deposition, and removal of sediments from the reservoir.
Sedimentation is steadily depleting reservoir capacity worldwide, threatening the reliability of water supplies, flood control, hydropower energy and other benefits that form the basis of today’s water-intensive society. The strategies available to combat reservoir sedimentation may be classed into four broad categories.
For relatively small reservoir the use of equipment such as drag line, A large number of multipurpose dams (hydro, dredging and hydro-suction on smaller scales to irrigation, urban water supply and navigation) are in solve the problem excessive sedimentation have been this category. In this case also the total sediment a success.
It lost nearly 53% of its million m3 and over an operating period of 40 years gross storage to sedimentation, which is presently the storage volume was reduced to 2600 million m3 estimated as reaching a volume of about 3.5 – 4.0 by sedimentation. million cubic meters since its operation in 1963.
