Saline water adversely affects crop production due to mismanagement of its use for irrigation. The yield of crops irrigated with saline water can be enhanced substantially, if an additional source of good quality water is available for use at critical times during the season. An alternative approach is to use the good quality water in blending mode. In the present book, Salt-Water-Atmosphere-Plant (SWAP) model used for its evaluation and scenario building capability in monsoon climatic conditions having the problems of saline groundwater. The contents of this book include: introduction that...

This study aims to determine land use change and runoff using the USDA Soil Conservation Service curve number (SCS-CN) method for Chaka block, located at 24o 47'00"N to 25o 47'00"N North latitude and 81o 19'00"E to 82o 21'00"E longitude, situated at Allahabad district, Uttar Pradesh .Antecedent moisture content (AMC) was calculated by taking preceding five days rainfall which gave three conditions AMC I, AMC II and AMC III. Weighted Curve Number for the entire selected micro-watershed was calculated based on site information of the block and found to be 78 for AMC II. The CN values...
