冲沟形成的主要原因是人为的：砍伐原生森林、开垦休闲地以及相关的径流系统水文条件的变化。冲沟的形成是非常密集的启动期间，当形态特征（长度，深度，宽度，面积和体积）是远远不稳定。一条沟壑约80%的长度、60%的面积和35%的体积仅在其5%的寿命内形成。这一发展阶段可以用一个动态模型来描述，以预测冲沟形态的快速变化。
The main causes of gully formation are anthropogenic: the clearing of native forests, tilling of fallow lands and associated change of the hydrological conditions in the rainfall-runoff system. Gully formation is very intensive during the period of initiation, when morphological characteristics (length, depth, width, area, and volume) are far from stable. About 80 per cent of a gully’s length, 60 per cent of its area and 35 per cent of its volume are formed in only 5 per cent of its lifetime. This stage of development can be described by a dynamic model to predict rapid changes of gully morphology.
