Water Resources on earth is limited and its availability is varied spatially and temporally. Adding to this the impacts of climate change and the rise in demand for water is adding stress on water resources day by day. To overcome or to cope up with these pounding conditions planning and management of water resources is essential. Understanding and assessing the hydrological components both quantitative (water balance) and qualitative (sediments and pollution loads) of a watershed is important for sustainable planning and management.
