Spatial and seasonal variation of surface water quality in Pillavakkal irrigation system

The surface water quality monitoring in a catchment is one of the most important tools for water management. The western zone of Virudhunagar district in south Tamil Nadu depends upon the surface water from Pillavakkal irrigation system, comprising a number of interconnected surface tanks. The increase in agricultural products and industrial zones in this terrain results in an essential investigation of the surface water quality and soil parameter.
