According to the hydraulic property of overflow weirs under steady flow, the flow patterns of overflow weirs were classified into free overfall and submerged overfall, and numerical models for unsteady flow were established to simulate the two flow patter

摘要为了对保水堰的交替水流进行数值模拟，依据保水堰恒定流情况下的工作特性，将保水堰的水流形态分成堰流和满流两种状态，分别建立保水堰不同流态下的非恒定流数学模型。
