This data release contains a comma-delimited ascii file of eleven same-day, discrete discharge measurements made at sites along selected reaches of Waikoloa Stream, Keanu'i'omanō Stream, and Wai'ula'ula Gulch, Hawai'i on October 27, 2021. 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 during fair-weather, low-flow conditions, generally characterized by negligible direct runoff within the reach. The measurements can be used to characterize the net seepage of water into (water gain) or out of (water loss) the stream channel between measurement sites provided that the measurements...

Groundwater levels have declined since the 1940s in the Wailuku area of central Maui, Hawaiʻi, on the eastern flank of West Maui volcano, mainly in response to increased groundwater withdrawals. Available data since the 1980s also indicate a thinning of the freshwater lens and an increase in chloride concentrations of pumped water from production wells. These trends, combined with projected increases in demand for groundwater in central Maui, have led to concerns over groundwater availability and have highlighted a need to improve understanding of the hydrologic effects of proposed groundwater withdrawals in the Waiheʻe, ʻĪao, and Waikapū areas of central Maui. A three-dimensional, variable-density solute-transport...
This data release contains a comma-delimited ascii file of seven same-day, discrete discharge measurements made at sites along selected reaches of Honokōwai Stream, Maui, Hawai'i on August 11, 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 during fair-weather, low-flow conditions, generally characterized by negligible direct runoff within the reach. The measurements can be used to characterize the net seepage of water into (water gain) or out of (water loss) the stream channel between measurement sites provided that the measurements were made during stable, nonchanging...

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 during fair-weather, low-flow conditions, generally characterized by negligible direct runoff within the reach. The measurements can be used to characterize the net seepage of water into (water gain) or out of (water loss) the stream channel between measurement sites provided that the measurements were made during stable, nonchanging...
This data release contains a comma-delimited ascii file of six same-day, discrete discharge measurements made at sites along selected reaches of Kahoma Stream, Maui, Hawai'i on November 30, 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 during fair-weather, low-flow conditions, generally characterized by negligible direct runoff within the reach. The measurements can be used to characterize the net seepage of water into (water gain) or out of (water loss) the stream channel between measurement sites provided that the measurements were made during stable, nonchanging...
This data release contains a comma-delimited ascii file of twenty same-day, discrete discharge measurements made at sites along selected reaches of Honokōhau Stream, Maui, Hawai'i on August 25, 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 during fair-weather, low-flow conditions, generally characterized by negligible direct runoff within the reach. The measurements can be used to characterize the net seepage of water into (water gain) or out of (water loss) the stream channel between measurement sites provided that the measurements were made during stable, nonchanging...
This data release contains a comma-delimited ascii file of ten same-day, discrete discharge measurements made at sites along selected reaches of Ukumehame Gulch, Maui, Hawai'i on June 7, 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 during fair-weather, low-flow conditions, generally characterized by negligible direct runoff within the reach. The measurements can be used to characterize the net seepage of water into (water gain) or out of (water loss) the stream channel between measurement sites provided that the measurements were made during stable, nonchanging...
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...
A three-dimensional, variable-density solute-transport model (SUTRA) was developed to evaluate the effects of three selected withdrawal/injection scenarios on salinity of groundwater (as simulated at damselfly anchialine-pool habitat) and discharge of freshwater to the nearshore environment of Kaloko-Honokōhau National Historical Park (KAHO), Hawaiʻi. A base model was constructed using water-level, salinity, and withdrawal data available during the period from 2009 to 2017. Groundwater recharge for the base model was from a published daily water budget representing rainfall for the period 1984-2008. The SUTRA code was modified to include simplified unsaturated zone properties in the subroutine UNSAT. Changes in...
This data release contains a comma-delimited ascii file of four same-day, discrete discharge measurements made at sites along selected reaches of Kanahā Stream, Maui, Hawai'i on June 1, 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 during fair-weather, low-flow conditions, generally characterized by negligible direct runoff within the reach. The measurements can be used to characterize the net seepage of water into (water gain) or out of (water loss) the stream channel between measurement sites provided that the measurements were made during stable, nonchanging flow...
