Withdrawal Effect

Summarized by Plex Health
Last Updated: 09 May 2022

A three-dimensional, variable-density solute-transport model was created to examine the results of 3 chosen withdrawal/injection circumstances on salinity of groundwater and discharge of freshwater to the nearshore environment of Kaloko-Honokohau National Historical Park, Hawaii. Groundwater recharge for the base model was from a released everyday water budget representing rains through 1984-2008. The SUTRA code was changed to include simplified unsaturated zone properties in the subroutine UNSAT. Changes in salinity of groundwater and discharge of freshwater relative to the base model were measured for 2 withdrawal and one injection circumstance. Model criterion values for the three-dimensional model were at first approximated utilizing a two-dimensional sample model and the model code SUTRA-MS, which allows simulation of both salinity and heat transport. This USGS data release includes all of the input and result data for the simulations defined in the linked model documents report.
