Irrigation water management plays a significant role in the economies of many developing countries. Developments in the system sciences, operations research and mathematical modeling for decision making under uncertainty have been successfully implemented for water resource management in many advanced countries. In this study we are presenting a two stage stochastic programming model for Indus basin irrigation system. This model takes inflow and rainfall as stochastic . We are presenting a comparison between the deterministic and the scenario-based stochastic programming models. We...
