|Title:||Preliminary investigation on environmental degradation due to salinization of river and groundwater in Thamirabarani Delta, South India|
|Keywords:||Seawater intrusion;Environmental degradation;Thamirabarani delta;South India|
|Abstract:||Present study consists analysis of data such as river discharge, cropping pattern, subsurface lithology and tidal fluctuations collected from Government organizations. Thematic maps pertaining to the study namely, drainage map, geomorphological map, lineament map and land use map were prepared from the satellite imageries. Well inventory survey and ground truth verifications were also carried out in this region. All spatial and non-spatial data were integrated using geographical information system (GIS). A site was selected for the construction of ‘Ogee’ type of surplus weir across the Thamirabarani River to minimize the salinisation of surface water and groundwater.|
