Nest-site selection by colonial waterbirds at Vedanthangal Waterbird Sanctuary, Tamil Nadu, India

Abstract :

In this paper an attempt has been made to understand the groundwater chemistry and its suitability for agriculture through Geographical Information System (GIS) in Marudaiyar basin, Tamil Nadu, South India. Water quality data were collected from the Water Resources Organization, Government of Tamil Nadu. The groundwater quality data consisting of Sodium Adsorption Ratio (SAR), Residual Sodium Carbonate (RSC) and Electrical Conductivity (EC) were drawn for water quality parameters in order to understand their spatial distribution in the basin. Following the water quality evaluation, thematic maps were generated and digitized; spatial analysis and integration were carried out to assess groundwater suitability for agriculture in the basin.
