Considerable reservoir seepage occurs in Xihe hydropower station .

A brief discussion on seismic design of high arch dams is made through the following three aspects:interaction of arch dams-foundation-reservoir water,dynamic stability of high arch dam abutment,effect of transverse slots on seismic design of high arch dam,and those aspects referred to above is not enough for seismic design of high arch dam.

In this paper feedback analysis has been made for the distribution characteristics of the reservoir water temperature field,foundation temperature field and dam body temperature field of Ertan Arch Dam.

To make sure whether the recharge water source of "Qinquan Culvert " is the reservoir water or the original groundwater being the key problem of success or failure of the scheme for its anti-hazard and strengthening.

There are multiaspects influence of soil and water loss on water quality of reservoir.

Effect of cage-culture fishing on the water quality of lakes and reservoirs and protection for water source;
