Analysis of Water Management in Sirsa Distric in Haryana; Model Testing andApplication

摘要

Through model simulations, different managerial solutions were evaluated forincreasing water-logging and secondary salinization in irrigated areas without sufficient natural drainage and suitable drainage outlets. Aquifers recharge in the already highly efficient irrigation system could be reduced by shifting to a delivery-based water-pricing system. The problems were significantly delayed and crop production slightly increased. Distribution of canal water proportional to the demands produced similar results while declining water-tables were also arrested. The tested solutions delay the occurrence of water-logging and secondary salinization, hence giving more time for the implementation of definite solutions: adequate drainage systems, drainage outlets, and adapted water management.
