St. Johns River Water Management District
June 2009 – September 2010
Project Lead: Wendy Graham
Project Participants: Lisette Staal (University of Florida)
Goals and Objectives
Every five years the St. Johns River Water Management District (SJRWMD) prepares a District Water Supply Assessment (WSA) and District Water Supply Plan (DWSP). The SJRWMD uses groundwater flow models to predict groundwater level change in the Northeast Florida aquifer systems that would occur if the additional water use forecast for the region was obrained strictly from groundwater. The predicted groundwater level changes in the aquifer systems are the basis for the determination of Priority Water Resource Caution Areas.
The SJRWMD contracted with the University of Florida Water Institute to facilitate a Groundwater Modeling Subgroup for the 2010 Water Supply Planning Process. The purpose of the Groundwater Modeling Subgroup was to assess the groundwater models used in support of the St. Johns River and Suwannee River Water Management Districts’ planning process for the Northern Planning Area, to identify weaknesses in the models that significantly limit the models’ acceptability, and to recommend improvements (if necessary) to make the models acceptable.
