Influence of changes in watershed landuse pattern on the wetland of Sultanpur National Park, Haryana using remote sensing techniques and hydrochemical analysis

Siltation from erosion and surface runoff due to mining and agriculture have led to the input of ionic components resulting in lake water quality deterioration as well as reduction in the depth of the lake available for rainwater accumulation. It has been inferred that high concentrations of nitrate (50% of samples above permissible limit (> 45 ppm)) and phosphate (50% of samples above permissible limit (> 0.1 ppm)) ions within the lake water is due to input from surface run off from the surrounding agricultural cropland within the lake catchment further leading to lake eutrophication and habitat loss suitable for plant and animal biodiversity.
