Question

The live storage requirement for a reservoir is to be determined by

Answer 1

Fundamentally, a reservoir serves to store water and the size of the reservoir is governed by the volume of the water that must be stored, which in turn is affected by the variability of the inflow available for the reservoir.

Answer 2

The live storage or useful storage is determined by the amount of the water available or which is stored between the minimum pool level (LWL) and the full reservoir level (FRL).

Where the minimum pool level or the low water level is determined only after considering the minimum working head needed for the turbines to work in an efficient manner.
