Abstract
Planned development and use of saline ground water in conjunction with limited fresh water supplies is essential in arid and semi-arid for reclamation and management of waterlogged saline lands. A decision model to aid in planning the optimal use of imported surface water and the salinej groynd water is formulated. The model is applied to a typical waterlogged saline area in the command of Western Yamuna Canal in Haryana (India) to determine optimal land and water allocation and the resulting salt and water balance in the unsaturated (crop root zone) and saturated zone (aquifers). The programme indicates that progressive development of ground-water will assist in reclamationof waterlogged saline lands and can increase farm income.
