Abstract:
The extensive canalization of the Doab, which was necessary to the development of irrigation agriculture induced added recharge to the ground-water system from the canal leakage. Disruption of the hydrologic balance of the regional flow system resulted in water-logging and soil salinization on a scale that threatens the entire economy of the region. The report establishes the cause-effect relationships involved and defines the functioning of the hydrologic system. Analog-simulation techniques for the analyses of ground-water systems in the Doab is developed. Analyses are made for (a) steady-state conditions that prevailed prior to the canal-irrigation period, and (b) non-steady state conditions for the canal-irrigation period from the year 1900 to 1960. The rise in ground-water levels, rate of infiltration from the main canals and their distributaries, net recharge rate to ground-water reservoir, and the effect of evapotranspiration on the rising groundwater levels are determined. Recharge to ground-water from the rivers Jhelum and Chenab and discharge through evapotranspiration are found to be the main sources for maintaining hydraulic dynamic equilibrium during the pre-irrigation period. Further analysis indicates that, during the canal-irrigation period, the infiltration from the main canals and their distributaries is the cause of rise in ground-water levels. The net infiltration rate is of the order of 1767 million gallons per day and is a function of canal size. Out of this, 867 million gallons per day is the loss due to evapotranspiration, showing its importance in the ground-water system of the area. Information resulting from this study provides a guide for more detailed study of the problem and establishes significant guidelines for future ground-water development in the Doab.
