An example of river bank erosion in Hong Kong

Abstract

A reach of the Kam Tin River in the vicinity of Kam Tin recently experienced accelerated bank erosion . The reach had previously been modified by the Water Supplies Department for gauging station purposes and it appears that this cleaning and reshaping of the channel may have contributed to these failures. Examination of the site suggests that hydraulic action and mass movement were two dominant processes.

錦田河在錦田咐近的河段， 現正在加速遭受岸蝕作用，此河段先前曾由水務局施工修整過，用作計量站的，同時水道所呈現新的沖刷方式可能會對河流的坍塌起一定的作用，現場調查提出了水力作用川和土體移動是的兩個主因。
