5-Ground water simulation for planning salinity management.

Abstract

Secondary salinization due to rise in water table is a growing problem in parts of Sirsa and Hisser districts of Haryana. Projections of waterlogged area made through simulation studies indicated that of the total area of 49,0000 ha, 70 percent would reach critical water table level of less than 3.0 m, and nearly 280,000 ha (57% of the total areas would be completely waterlogged with water table within 1.0 m, by 2000 A.D. This calls for introduction of antiwaterlogging measures. The differential rate of rise in water table in different parts of the area provides scope for carrying out improvements over a period of time.
