The two main technical tools included in the Groundwater Management and Exploration Package are GRACE and WEAP. GRACE is a satellite monitoring earth’s gravity fields which has a direct correlation to groundwater storage. GRACE information will form the base in GMEP to assess current and past groundwater trends. WEAP (Water Evaluation And Planning system) is a user-friendly package able to link supplies and demands in water resources and will be used to evaluate future alternatives in sustainable groundwater management.
