Geospatial Resources of Water Management for Agricultural Systems (GROWMAS) is an online analytical platform which empowers local water agencies and Groundwater Sustainability Agencies (GSAs) to monitor, analyze and visualize historical and near real-time groundwater changes. GROWMAS provides the Monthly and Annual Net To/From Groundwater (NTFGW) maps to the agencies and helps them to achieve the groundwater sustainability.

GROWMAS uses the Mapping Evapotranspiration at High Resolution with Internalized Calibration (METRIC) as the engine to calculate spatial actual evapotranspiration values – at the field level – in a given area through an automated system. It incorporates the estimated ET values with surface water delivery, spatial precipitation, and runoff data in the region to create spatial monthly and annual Net To and From Groundwater (NTFGW) maps.

There is no need for any metered groundwater pumping data, and the historical satellite imagery data are freely available. GROWMAS processes the satellite imagery and integrates several sources of data under one platform.

GROWMAS is a user-friendly online portal that automates the production of Monthly NTFGW maps of a region. It offers ongoing support to local agencies looking to develop and implement a Groundwater Sustainability Plan (GSP).
