堰闸站的流量资料整编,一般均采用过闸流量系数法,根据闸型和流态,选择相关因素与流量系数建立关系,然后再做辅助曲线进行推流,工作烦琐,不利于电算整编。现用落差指数法探求在新建堰闸出现淹没式堰流时的流量单值化处理。一、新建港基本情况落差指数法适用于河床稳定受洪水涨落和变动回水混合影响下的天然河道中下游水文测站的流量校正计算。新建港水闸为直立式平扳闸门, Weir gate station flow data reorganization, generally have used the gate flow coefficient method, according to the gate and flow patterns, select the relevant factors and flow coefficient to establish the relationship, and then do the auxiliary curve to push, cumbersome work, is not conducive to the computer reorganization . Now drop index method to explore the emergence of submerged weir flow in the new weir flow single-valued treatment. First, the basic situation of the new port drop index method applies to the river bed stability under the influence of flood fluctuations and changes in backwater mixing natural hydrological stations downstream hydrological correction calculation. Newly built port sluice gate for the vertical type,
