Hydrological Status of a Few Tanks in and Around Mysore a Study Using Gis and Remote Sensing

Abstract

Hydrological Status Of A Few Tanks In And Around Mysore A Study Using Gis And Remote Sensing Urbanization is a very important factor leading to the deterioration of small tanks, which are a popular and decentralized means of runoff harvesting in the South Indian plateau.

The city of Mysuru is host to a large number of tanks, which are prone to destruction due to rapid urbanisation and lack of measures to prevent their fall. Dalavayi tank in the city has been studied in the present work to understand its present status and to suggest steps that are necessary make it more beneficial to the urban and rural population using it.

Conclusion

The hydrological investigations of Dalavayi tank in Mysuru city indicate that the tank gets huge amounts of inflow in rainy seasons, and this water can be used for irrigation and aquaculture. During the dry season, the capacity of the tank can be better used by allowing pre-treated sewage. It is observed that quality of the water improves along the downstream of the tank because of the self purification process – most of the water quality parameters tested in the surface water are well within the desirable limits.
