SUTRA model used to evaluate groundwater availability in central Molokai, Hawaii
A three-dimensional, variable-density solute-transport model (SUTRA) was developed
to evaluate the effects of nine selected withdrawal/recharge scenarios on salinity of
groundwater and discharge of freshwater to the nearshore environment of central
Molokaʻi, Hawaiʻi. The model was constructed using water-level and salinity data
available for the period from 1940 to 2012. Groundwater recharge for the model was
estimated using a daily water budget for the period of interest. Inflow of groundwater
at the model boundaries was estimated from an islandwide model based on a
sharp-interface approach (SHARP). The island-wide model is included as part of
this data release. The data release also includes the SUTRA and SHARP source
codes and executable files used to run the simulations. The SHARP code was
modified for input/output related to computing the boundary flows and the SUTRA
code was modified to include simplified unsaturated zone properties in the subroutine
UNSAT. This USGS data release contains all of the input and output files for the
simulations described in the associated model documentation report
(https://doi.org/10.3133/sir20195150).
