辽宁省喀左县瓦房店水库位于县城西部15km,拦截大凌河北支大营子、六官支流,主河道长度18.6km,集水面积120km~2。土坝坝高33.3m,死库容457.7万m~3,兴利库容901万m~3,肪洪库容1948万m~3,总库容3307万m~3。多年平均输砂模数为2000t/km~2·a,年平均淤砂量为28.8万t(22.15万m~3),设计淤积年限20年。水库设计标准为2%频率,设计洪峰流量1820m~3/s,保坝标准采用0.01%频率,相应洪峰流量3720m~3/s。
The Kawan County Wafudian Reservoir in Liaoning Province is located 15km west of the county seat and intercepts the Dabayizi and Liuguan branches in the northern branch of Daling River. The main channel length is 18.6km and catchment area is 120km ~ 2. The earth dam height is 33.3m, the dead storage capacity is 4.577 million m3, the storage capacity is 9.01 million m3, the flood storage capacity is 19.48 million m3, and the total storage capacity is 33.07 million m3. The annual average sand transport modulus is 2000t / km ~ 2 · a, the annual average amount of silt is 288000 t (221 500 m ~ 3), and the design silting life is 20 years. The design standard of the reservoir is 2% of the frequency, the design flood peak flow is 1820m ~ 3 / s, the dam safety standard adopts 0.01% frequency, and the corresponding flood peak flow is 3720m ~ 3 / s.
