Seasonal variation of physico chemical properties of ground water in rainfed agricultural area of Shivalik foot hills at pandoga sub watershed, Una district of Himachal Pradesh
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 12
Abstract
Water is a critical and basic resource for human survival, economic development and ecological balance in nature. Rainfall in India, the primary source of sweet water, is characterized as erratic in quantum, intensity and distribution. India shares about 16% of the global population but it has only 4% of the total water resources. The hydrological challenge is to relocate four months rainwater in time to year round for multifaceted uses: drinking, domestic consumption and life saving irrigation (food security) in rainfed areas. Watershed management is recognized as an efficient way of intervention for integrated natural resource management in rainfed systems. Intervention changed cropping pattern and utilization of water for irrigation which may changed the quality of water by leaching of different metals and ions. Physico chemical parameters of water [ temperature, pH, TDS, EC, dissolved oxygen, biological oxygen demand(BOD) and chemical oxygen demand(COD)] shows that parameters fluctuated with the seasons and sites. Season wise result shows that maximum mean of all parameters was higher in pre monsoon season as compared to post monsoon season and mean values of all parameters were within permissible limits in both seasons as compared to WHO standard.
