erosion sediment yield

Factors affecting the processes of soil erosion and sediment yield have more asymmetry and variability and enhance the complexity of modeling sediment yield in different scales.

影响侵蚀产沙过程的因素在时空上具有很大的不均匀性和变异性，增加了不同尺度间侵蚀产沙模拟的复杂性。

In this research, soil erosion and sediment yield was calculated by runoff shear stress, runoff energy consumption and runoff power theory respectively.

分别利用坡面径流剪切力、坡面径流能耗和坡面径流单位水流功率理论对坡面土壤侵蚀发生过程进行了研究。

So studying water erosion and probing the laws of sediment yield, have significant production practice meaning to the prevention and cure for soil erosion and all kinds of silt disaster.

因此开展水力侵蚀的研究，探索水力侵蚀产沙规律，对于土壤侵蚀的防治和各类泥沙灾害的治理，具有极大的生产实践意义。
