侧蚀

此后至25.5小时，网状河道的演变以下蚀为主演变为以适度的侧蚀，但河岸的后退幅度很小，标志网状河道逐步过渡到成熟期。

Hereafter up to 25.5 hours the evolution fashion of the anastomosing river changed from downcutting erosion to lateral erosion , but the fall back of channel banks is not evident . It indicates that the anastomosing channels change into their autumn .

大气降水既增大了斜坡的静水压力，又减弱了岩土体的抗剪强度，河流侧蚀掏空坡脚，使岩体失去支撑以及人类工程活动破坏斜坡稳定条件等因素是滑坡形成的外在原因。

Precipitation , unsupported rock body from erosion of river , human activity are external reasons .
