| The objective of this study is to propose reservoir operation method in relation to the suspended sediment concentration due to rainstorms. Present analysis is made for the Tamjin reservoir which is under construction. For the hydrologic computations the Huff rainfall distribution, Clark unit hydrograph method and Puls reservoir routing method are used. The variation of suspended sediment concentration is calculated by 2-dimensional RMA-4 model. As a result of this study, the possible intake time from the reservoir under low frequency flood is estimated and the rainfall-ret urn period - possible intake time relationship is established, which is very important in maintaining the water quality standard when supplying water from the reservoir for different utilizationurn period- possible intake time relationship is established, which is very important in maintaining the water quality standard when supplying water from the reservoir for different utilizations.£¿£¿£¿£¿Í»£¿£¿£¿£¿¡¦£¿£¿£¿£¿û©ðÍ£¿ |
