Abstract: In the review of bidding design of reservoir sediment monitoring system for Dagangshan hydropower station, based on the hydrological data of middle reach of Dadu river and the sediment inflow after power generation, the scheme was advanced that two inflow hydrological stations, one outflow hydrological station and monitoring sections should be optimized. As well, water level monitoring station should be built. The scheme would satisfy the need of normal operation of the hydropower station and cut the cost. The optimized monitoring sections and newly built water level monitoring station would enhance the rationality of the whole sediment monitoring system and save resources during operation, which is of great importance and worthy reference.

Key words: hydrological station, water level monitoring station, bidding plan, sediment monitoring section, optimizing design
