我国已建水库大多从安全角度出发在整个汛期采用固定汛期限制水位渡汛,造成部分水库出现汛期不敢蓄水且弃水较多、汛后却难以蓄满的现象,在一定程度上影响了水库综合利用效益的发挥。文章结合已开展汛期动态控制水位试点工作的水库取得的理论及应用成果,系统论述水库汛期水位动态控制应用的条件、汛期水位动态控制方案以及相应的风险和效益。
Most of the reservoirs built in our country have adopted a fixed flood season to limit the flood water level during the whole flood season from the point of view of safety. As a result, some reservoirs did not dare to store water during the flood season and more abandoned water, but it was difficult to accumulate after flood, which affected to a certain extent Benefit of comprehensive utilization of reservoir. Combining with the theory and application results of reservoirs that have carried out pilot project of dynamic control of water level in flood season, the article systematically discusses the application conditions of dynamic control of water level in flood season, the dynamic control scheme of water level in flood season and the corresponding risks and benefits.
