Georgakakos, A., M. Kistenmacher, K. Yu, and H. Yao,“Georgia Water Resources Planning Tool.” This software was developed for the Georgia Environmental Protection Department to support the state water resources planning process. The planning tool determines (1) the water available for consumptive use at an individual sub-basin, (2) the share of each sub-basin required to support downstream flow regime requirements, and (3) the benefits of alternative development plans and management practices such as conservation measures, return rates, basin transfers, and basin storage.
