Available data since the 1980s also indicate a thinning of the freshwater lens and an \nincrease in chloride concentrations of pumped water from production wells. These trends, \ncombined with projected increases in demand for groundwater in central Maui, have led to \nconcerns over groundwater availability and have highlighted a need to improve understanding of \nthe hydrologic effects of proposed groundwater withdrawals in the Waihe\u02bbe, \u02bb\u012aao, and Waikap\u016b \nareas of central Maui. A three-dimensional, variable-density solute-transport model (SUTRA) was \ndeveloped to evaluate the effects of seven selected withdrawal/recharge scenarios on water \nlevels and salinity of groundwater in central Maui, Hawai\u02bbi. The model was constructed using \nwater-level and salinity data available for the period from 1926 to 2012. Groundwater recharge for \nthe model was estimated using a daily water budget for the period of interest. Inflow of \ngroundwater at the model boundaries was estimated from an existing island-wide numerical \ngroundwater-flow model (Izuka and others, 2021, available at https://doi.org/10.3133/sir20205126).\nThe data release also includes the SUTRA source code and executable file used to run the \nsimulations. The SUTRA code was modified to include a simplified representation of water-table \nstorage (Gingerich, 2008, available at https://pubs.usgs.gov/sir/2008/5236/; Gingerich and Engott, \n2012, available at https://pubs.usgs.gov/sir/2012/5010/).
