1 Overview Yumen River anti-regulation reservoir is located in Luoning County, Henan Province, Hing Wah Township Yumen River Village, a branch of the Yellow River Luohe River. The control area of the dam site is 6104km ~ 2, with an average annual runoff of 1.262 billion m ~ 3. 28.1 million m 3 storage capacity for medium-sized reservoirs. The dam is a Grade 3 building with a roller compacted concrete gravity dam with a maximum dam height of 59.5m. Power station for the dam type, a total of 3 units, with a total installed capacity of 10.5MW. The upstream cofferdam adopts earth-rock crossing cofferdam, the axial length is 138.24m, the average elevation of riverbed is 393.44m, the water retaining level is 397.27m in 5 years of dry season (Q = 150m ~ 3 / s), the crest elevation is 397.6m, the maximum height of cofferdam 7.6m. The downstream cofferdam axis length of 150.35m, average riverbed elevation 392.89m, 5 years, a dry season 391.72m retaining water, weir crest 392.0m, cofferdam maximum height 3m. On the downstream Wai
