$1.$ The monthly inflows $($S$)$ the monthly evaporation $($E$)$ estimates, and the monthly amounts of net precipitation $($P$)$ on the mean pool level at the site of a proposed reservoir during a critical flow are given in the following table. A monthly uniform mandatory reicase $($DR$)$ of $01*10*$ m$\text{'}/$month is needed for downstream requirements. The monthly water demands $($D$)$ to be met from the active storage capacity are also listed in the table.

$3)$ Find the required storage capacity of the reservoir by an operating study method.

b$)$ For the capacity that you have found, calculate the monthly reservoir contents and spills from the reservoir.

Values in $10\%$ m$/$month$.$
