Abstract

The rising demand for water, specifically for irrigated agriculture, which consumes nearly 80% of the world’s developed water resources (Wolff and Stein 1999), has brought new challenges to water resources planners and managers. A major part of the consumable water resources exists as groundwater. Sustainability of irrigated agriculture, therefore, demands either the development of additional water resources or efficient management of the available water resources under the existing scenarios. Shortages of surfacewater supplies necessitate the development of groundwater in many canal commands that can be used optimally in conjunction with surface supplies. The joint use and management of surface-water and groundwater resources to maximize reliable supply and minimize damage to the quantity or quality of the resources is known as conjunctive use (Hanson et al. 2010). Conjunctive-use management has been the most suitable alternative for optimum utilization of available land and water resources.
