Wetland design can moderate peak flow rate and volume ofrunoff discharge and sediment deposition during precipitation events.
湿地项目可以缓和雨洪峰值流率及降水过程中的径流排放量和沉淀量。

Disturbance of the bedrock changes drainage and runoff patterns, which may increase the rateof erosion. Trenching is the exploration activity that most disturbs bedrock.
干扰的基岩排水和径流的变化模式，这可能增加侵蚀率。挖沟是勘探活动，大部分干扰的基石。

Being based on the runoff plot investigations, a dynamic model of grey systems about the rainfall, the runoffrate and the soil erosion was introduced by using the grey systems theory.
