drainage basin yield

基本解释

The DYRM was run to simulate the process of water and sediment yield on slopes in the Middle Yellow River basin, considering the drainage division of water and sediment source areas.
在黄河流域产水产沙子系统修正分区的基础上，用黄河数字流域模型模拟计算中游流域的产水、产沙过程。
Research on drainage basin erosion and sediment yield amount is not only an important task in physiognomy, but also an important one in river harnessing and water conservancy construction.
流域综合治理规划、防治土壤侵蚀、合理利用水沙资源，无不需要掌握流域产沙情况。
Drainage area(A)is a lumped variable as all the environmental variables are involved within it, and specific sediment yield(Ys)is an index of soil erosion intensity of some drainage basin.
流域产沙模型是研究土壤侵蚀和水土流失的主要方法，是解决流域生态和环境问题的有效途径。
