The useful storage is the volume of water stored in the reservoir between                        

The water stored in the reservoir below the minimum pool level is called                        

For a flood control reservoir, the effective storage is equal to                        

Trap efficiency of a reservoir is a function of                        

The total capacity of a reservoir is 25 million cubic metres and dead storage is 5 million cubic metres. If the average volume of sediment deposition is 0.10 million cubic metre per year, then the usefulness of the reservoir will start reducing after                        

When the upstream face of a gravity dam is vertical, then the intensity of water pressure at the water surface and at the base respectively will be
where w is unit weight of water and H is the depth of water.
