枫树坝水库坝址流域内雨量站站网优化

Optimization of rainfall station network in the river basin of Fengshuba Reservoir

应用新安江模型对东江流域枫树坝水库坝址以上流域内的雨量站网进行优化,并且应用优化前后的降水资料进行模拟、采用洪水资料进行验证,结果表明可将原有14个雨量站调整为10个。优化后的雨量站网观测资料不仅满足水文模拟精度的要求,而且降低了费用,从而为流域内的雨量站网布设提供了科学依据。

Using xin＇anjiang model, has optimized the rainfall station networks in Dongjiang River Basin of Fengshuba Reservoir. Then the precipitation data has been simulated by the normal and optimal rainfall information respectively, and identified by the flood data. The results have shown that the 14 rainfall stations can be reduced to 10. The observed data which comes from the optimized rain--gauge networks not only meet simulation precision but also reduce the cost. So, it can provide the scientific basis for the raingauge network arrangement.
