Kerala State can be broadly divided into three well definable zones, with high mountains of Western Ghats extending NW-SE in the east (Precambrian), a long narrow coastal plain in the west (Recent), flanked by Arabian Sea, and an undulating terrain (Precambrian and Tertiary) in between. Laterite in different forms is a ubiquitous rock in most of the places. River restoration has drawn considerable attention across the world as river systems are variously affected due to human intervention and in many cases irreversible changes have taken place. Due to high population density, with intense use of land and indiscriminate resource extraction, rivers in Kerala are under stress as has been reported in various studies. Restoration plan warrants proper understanding of the river system. This paper discusses various geo-environmental issues that impact the river system. Physical characteristics of the rivers have been deliberated and problems are identified. It is suggested that restoration of rivers warrants catchment scale approach considering all parameters, local initiatives like river bank mapping and involvement of all stake holders.
