Problem of encroachments on the river Kaveri area is grave and affects the rural environment of this region during seasonal and flash floods. Like the problem of polluted waters, that of encroachments is quite common with almost all the rivers and streams. The first type of encroachment comes from the builders of houses and other concerns. Due to the steep growth of population in Kaveri delta area, and concentration of more rural villages are being affected. The area on the banks of the Kaveri which generally lies vacant and unused seems to be an ideal place for constructing houses and other encroachments. Thus unauthorized colonies and houses are being built on the banks of the Kaveri. Second type of encroachment is by the farmers who own lands adjoining to the Kaveri. The greed for more yields and more income at any cost has led the farmers to hunt for more land. For the gross root level study and to use the GPS survey the entire river length (77 km) has been divided into five zones and identified the encroachments.
