Irrigation systems changed significantly, now increasingly

dependent on groundwater. Simultaneously, groundwater depletion and waterlogging. Existing SW and GW institutions need to reorient while

moving towards groundwater management; Water availability !!! m"#capita, li$ely to dip further i.e.

:echarge potential in different irrigated areas was estimated; Surface and groundwater analysis for 29)*, including estimation of

groundwater pumping in the area; Groundwater management approaches adopted abroad studied;

Groundwater management opinion survey; Irrigation system operations studied with necessary modificationsre uired for better groundwater management;
