According to the watershed forms of Sichuan province, the paper present a fea- sible method of flood rechecking for dams of small reservoirs, which is valuable for dams have similarity in watershed form and project scale.

According to "Standard for Classification and Flood Control of Water Resources and Hydroelectric Projects"(SL252-2000) and "Classification & Design Safety Standard of Hydropower Projects"(DL5180-2003), the standard of Spillway Design Flood for first chop large scale earth and rockfill dam must be Probable Maximum Flood, or recurrence interval of ten thousand years.

Regulation of flood resources in detention plain reservoir;

Optimal utilization of regional flood resources based on equal-marginal principle;

Research on exploitation model for flood resources storage based on shallow sea reservoir construction;

Taking Baicheng region as an example,this paper presents a flood resources optimal allocation model based on the principle of flood resources utilization,which consists of selection measures,system design and real-time distribution of flood in different frequency.

Based on the new period water-control concept, with the overall plan of controlling blood and promoting benefit, the utilization of flood resource multi-angled and wholly transit the idea of flowing into the sea is safe" , put technological means and engineering practice together to conduct effective flood regulation.

Utilization of flood water resources is an important way of solving the shortage of water resources in Weifang City.
