1. A reservoir has the following inflows and outflows (in cubic meters) for the first three months of the year. If the storage at the beginning of January is 60 m3, determine the storage at the end of March. Month Jan Feb Mar Inflow Outflow

Solution

Storage at end of March = Storage at beginning of January + Cumulative inflows - Cumulative outflows

=60+(4+6+9)-(8+11+5)

=60+19-24

=55 m³
