How to Determine Capacity of a Storage Reservoir? | Water Engineering
The capacity of a storage reservoir is determined on the basis of the inflow to the reservoir and the demand of the consumers (or the yield of the reservoir). The following two methods are generally used for determining the capacity of a storage reservoir: 1. Analytical Method: In this method an analysis of demand and inflow of water per month of the year is made. The
