Abstract:
A   classical   approach   in  evaluating   potential   of	a
proposed  river  basin  impoundage mainly consists of a   statistical analysis   of   the   precipitation data,  leading to   a   quantum   of runoff   of  the desired  reliability.   Over the years  the   role   of carryovers   in   'raising  the potential  was  recognised   and,   recent works  evolved  a  method of optimising the quantum of carryovers  by using  a  technique of  simulating the operations of the  impoundage, on  the basis  of'-historical  data  of  rainfall  and  runoff.
