Groundwater Recharge in Hawaiʻi
Groundwater provides 99 percent of Hawai‘i’s drinking water and about 50 percent of all freshwater used in the State. Groundwater recharge is water derived from precipitation and other sources, such as irrigation and leakage from surface reservoirs, that moves through or bypasses the plant-soil system and replenishes aquifers. Groundwater availability in Hawai‘i is affected by changes in...
Model subareas and moisture zones used in a sensitivity analysis of a water-budget model completed in 2022 for the islands of Oahu and Maui, Hawaii
A sensitivity analysis of groundwater-recharge estimates from a water-budget model was completed for the islands of Oahu and Maui, Hawaii (Johnson and others, 2023). Results of the sensitivity analysis were used to quantify the relative importance of selected model parameters to recharge estimates for three moisture zones (dry, mesic, and wet) on Oahu and Maui. These shapefiles contain the boundar
Seepage-run discharge measurements, March 23, 2022, He'eia Stream and 'Ioleka'a Stream, O'ahu, Hawai'i
This data release contains a comma-delimited ascii file of 15 discrete discharge measurements made at sites along selected reaches of He'eia Stream and 'Ioleka'a Stream, O'ahu, Hawai'i, on March 23, 2022. These discrete discharge measurements form what is commonly referred to as a "seepage run." The intent of the seepage run is to quantify the spatial distribution of streamflow along the reach dur
Seepage-run discharge measurements on the islands of O'ahu, Moloka'i, Maui, and Hawai'i, 2018 to 2022
This data release is part of a cooperative study to assess streamflow availability under low-flow conditions for streams on the islands of O'ahu, Moloka'i, Maui, and Hawai'i from 2018 to 2022. This data release contains 24 child items that consist of the following files: (1) a metadata xml file describing the data release files and data attributes, (2) an annotated NWIS-Mapper screen-captured imag

Groundwater and surface-water interactions in the He‘eia watershed, O‘ahu, Hawai‘i—Insights from analysis of historical data and numerical groundwater-model simulations
He‘eia and ‘Ioleka‘a Streams in the He‘eia watershed on O‘ahu, Hawai‘i, receive substantial discharge from dike-impounded groundwater. Previous studies indicated that groundwater withdrawals from the watershed affect streamflow. Resource managers and users seek information that can be used to balance the needs of competing uses of groundwater and streamflow in the watershed.In this study, analyses
