The three-dimensional, variable-density solute-transport groundwater model was created to evaluate the effects of nine selected withdrawal/recharge scenarios on salinity of groundwater and discharge of fresh groundwater to the nearshore environment of central Molokaʻi, Hawaiʻi. An existing USGS numerical groundwater-flow model of Molokaʻi (Oki, 1997, 2006, 2007) was used as a basis to develop updated numerical models to address information needs related to: (1) quantifying the effects of pumping existing or proposed wells on salinity of groundwater and discharge of groundwater near the coast, (2) identifying areas for new groundwater development in central Molokaʻi, (3) distributing pumping to increase the overall amount of fresh groundwater developed in the Kualapuʻu area, and (4) estimating the long-term effects of potential reductions in groundwater recharge on groundwater availability. The development of the models included in this data release is documented in U.S. Geological Survey Scientific Investigations Report 2019-5150 (https://doi.org/10.3133/sir20195150).
