| Abstract | The effects of the Bhumiphol and Sirikit Reservoirs on the Ping and Nan river flow conditions are determined in terms of the shapes of hydrographs as well as in percentage of reduction of annual flood peak discharges and water levels. Streamflow Synthesis and Reservoir Regulation Model or in short the "SSARR" Model is used to determine the degree of regulation of both dams in terms of the shapes of hydrographs in the years 1968, 1971 and 1975 along Ping River and at Nakorn Sawan and in the years 1971 and 1975 along Nan River. The results are provided along Ping River at Bhumiphol Damsite, Tak, Kamphaeng Phet; along Nan River at Sirikit Damsite, Uttaradit, Phitsanulok, Phichit and in the Chao Phya River at Nakorn Sawan. The frequency analysis on the annual flood peak discharges and water levels are performed using lognormal distribution at the stations along Ping and Nan Rivers from the tail of dams to Nakorn Sawan. General conclusion is drawn in terms of reduction of the peak flood magnitudes due to the dams. It is found that both the annual peak discharges and water levels are reduced approximately by 70% at both damsites. The percentage of reduction diminishes progressively downstream and is approximately equal to 25-30% at Nakorn Sawan. |
