| Abstract | The objective of this study is to analysis the affect of structure measure of basin wide to flood mechanisms. The study focus on flood area in Phrae Province, which know as the small valley in Yom river basin. Field survey was done to assess soil characteristics in the Yom river basin, fifty five samples were collected for nine different soil types. The results of the analysis shows that, the soil moisture content at field capacity in the study area range from 0.3 0.4 % Hydraulic conductivity on the hand has a wide range from 1.4 x 10 -4 m/s for sandy soils to 2.5 x 10 -7 m/s for clayey soil. The mathematical model Mike 11 was applied for Yom river basin. Historical data of floods during the 1994 and 1995 periods were used for calibration and verification of the model. Simulated water levels at two stations have very good fitting with the observed data. The Yom river basin presents one of the most serious flood problems in Thailand. In order to reduce flooding in Phrae city, two reservoirs are proposed at the upper reach of the basin namely reservoir 1 and reservoir 2. The results show that, with these two reservoirs, the flood levels were reduced about 0.3 m and a 10 square kilometer inundation area in the Phrae Province is reduced. The 100 year return period flood of 1995 proves to overcome the flood prevention capacity of the two proposed reservoirs in the Yom river basin. The model was run for the case of the proposed Kaeng Sua Ten reservoir which has a bigger capacity. It is found that, the flooded area reduced 48 % with the reservoir. |
