Waterlogging and salinization due to rise in water table is a growing problem in parts of Lower Ghaggar Basin in Bhakra Canal Command area. An existing groundwater simulation model (developed by Tyson and Weber, 1964) to predict water table behavior has been calibrated with historical data. The verified model was used to predict water table levels upto 2000 A.D. under different irrigation system improvement scenarios. Projections of waterlogged area, made through simulation studies, indicated that, of the total area of 490,000 ha, 70 percent will reach critical water table level of less than 3.0 m, and nearly 280,000 ha (57% of the total area) will have water table within 1.0 m by 2000 A.D. if irrigation system is not improved. This calls for the introduction of waterlogging prevention measures. Irrigation system improvements in the form of lining of watercourses, minor and distributaries and improvement of on-farm management could reduce the groundwater accretion by 75% of the existing levels and thereby reduce the waterlogging. The differential rate of rise in water table in different parts of the area provides scope for carrying out improvement over a period of time.
