Analysis and Recommendations for Integrated On-Farm Water Management in Haryana,India: A Model Approach. Indo-Dutch Operational Research Project on Hydrological Studies

摘要

The rapid increase in irrigated land in Haryana State (India) during the last twodecades has destabilized regional water and salt balances. Field experiments in Hisar indicated possibilities of halting this imbalance by alternative water management interventions. Water and sale balances were analyzed with the transient moisture-solute transport model SWAP. Model simulations were performed for all agro-climatic zones in Haryana. A decision-support system around the SWAP model was developed to guide water managers in making decisions on canal water allocations. The analysis indicated that the total utilizable water resources are sufficient, but that a redistribution at State level is required.
