大量的实验证明，合理开发利用浅层咸水，使咸水水位降低到合理水平，可以：避免地下水的无效蒸发，增加水资源量；增强调蓄能力和抗早防涝能力；促进浅层咸水淡化，改造盐碱地，改善生态环境；减轻对淡水资源的威胁。

The result shows that the erosion presents as incision when the riverbed is relative narrow and deep; To the low-water branching reach with strong boundary conditions where the riverbed is wide and shallow, the scour and deposit variation characteristics mainly presents as erosion and deposition adjustment of river island, height deviation of thalweg in the inlets and the adjustment of split ratio after impoundment To the low-water branching reach where the riverbed is wide and shallow and the lateral boundary conditions are weak, the scour and deposit variation characteristics is not restricted to the adjustment of split ratio, and the pattern of the braided reach may even be changed.

结果表明：当河段相对窄深时，河段冲刷主要为下切；当河段为相对宽浅的低水分汊河段且河岸约束较强时，蓄水以后的冲淤变化主要体现为江心洲滩的冲淤调整、汊道深泓高程差的冲淤调整，并引起主支汊分流比的调整；当河段为较为宽浅的低水分汊河段且河岸约束相对较弱时，则冲刷调整不仅限于分流比的调整，甚至会导致大的分汊格局的调整。
