Reservoir operators and managers need to present a rational basis of determining releases for a flood event. This study divides a forecasted flood hydrograph by two parts on the basis of non-damaging discharge, which consists of one part con,trolled by non-damaging discharge and another controlled by using flood control storage of the reservoir. In case of using flood control storage, a new reservoir operation method. called TRF (Transformed Reservoir Flood) ROM, is suggested for the operating rules during a flood to consider the reservoir security as well as the operational efficiency. This paper presents an application of the methodology to the operation of a single multipurpose reservoir at the Taechong Dam during flood and the results analyzed.alyzed.

Reservoir operation during flood period can be divided into two parts: One is for an operating policy during flood period to consider water conservation and flood control, and the other is for flood time on a random water level at flood forecasting, This study is concerned with reservoir operation and discusses general reservoir operation at flood time. Flood control has problems such as the uncertainty of hydrologic models. technical limitations and some constraints. Therefore, we may prepare the quantitative flood control methods based on the assured flood control storage for reservoir operation. Transformed Reservoir Flood(TRF) Reservoir Operation Method(ROM) is a procedure which determines the adequate releases with considering dam safety for flood inflows over non-damaging discharge. Based on the TRF ROM which was explained in our published paper. the study discusses the TRF ROM with additional investigations and the general reservoir operation rules at flood time.
