These shapefiles represent the spatial distribution of mean annual water-budget components, in inches, for the Island of Maui, Hawaii for a set of eight future climate and land-cover scenarios. The future climate conditions used in the water-budget analyses were derived from two end-of-century downscaled climate projections including (1) a projected future climate condition representative of phase

This data release contains inputs and outputs needed to reproduce the Soil and Water Assessment Tool (SWAT) model findings for the publication: Fortini, L.B., Leopold, C.R., Perkins, K., Chadwick, O.A., Yelenik, S.G., Jacobi, J.D., Bishaw, K., II, Gregg, M. and Rosa, S., 2020, Local to landscape-level controls of water fluxes through Hawaiian forests: Effects of invasive animals and plants on soil

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 Molokai, Hawaii. The model was constructed using water-level and salinity data available for the period from 1940 to 2012. Groundwater recharge for the

This data release contains the shapefiles of mean annual water-budget components for Guam for historic (1990 - 2009) and future (2080 - 2099) climate conditions. Components estimated for the 1990 - 2009 scenario represent an update to the historic (1961 - 2005) components estimated by Johnson (2012), and serve as a historic baseline for the components estimated for the future (2080 - 2099) climate

This data release contains the input files for the watershed and water-balance models that simulate historic (1990-2009) and future (2080-2099) climate conditions on Guam. These simulations are described in the associated Scientific Investigations Report, "Water Resources on Guam-Potential Impacts of and Adaptive Response to Climate Change" by Stephen B. Gingerich, Adam G. Johnson, Sarah N. Rosa,

A previously published three-dimensional, groundwater model (SUTRA) (http://doi.org/10.3133/sir20135216) was used to evaluate the effects of future climate and withdrawal on the freshwater lens of Guam. The model was run using 2080 to 2099 estimated recharge and sea-level rise. This USGS data release contains all of the input and output files for the simulations described in the associat

This dataset describes land cover and vegetation for the island of Maui, Hawaii, circa 2017, hereinafter the 2017 land-cover map. The 2017 land-cover map is a modified version of the dataset titled "Mean annual water-budget components for the Island of Maui, Hawaii, for recent conditions, 1978-2007 rainfall and 2010 land-cover map" by Johnson (2015), hereinafter the 2010 land-cover map.

The U.S. Geological Survey Pacific Islands Water Science Center and the University of Hawaii at Manoa Department of Geography, in cooperation with the U.S. Department of Interior Pacific Islands Climate Adaptation Science Center initiated a field data-collection program as part of a study to quantify the impacts of drought on water resources and the importance of cloud-water interception in mitiga

The U.S. Geological Survey and the University of Hawaii at Manoa, in cooperation with the County of Maui Department of Water Supply and the State of Hawaii Commission on Water Resource Management, initiated a field data-collection program to provide information for evaluating how infiltration rates and soil hydrophobicity are dependent on plant species type within forested areas on the island of M

The purpose of this release is to make available the quality-assured pesticide-concentration results for 32 discrete water samples that were collected on the islands of Kauaʻi and Oʻahu between November 21, 2016 and April 29, 2017. This webpage includes brief descriptions of the sampling sites, the samples collected, streamflow conditions during sampling, sample-collection and filtration methods,

The shapefile associated with this metadata file represents the spatial distribution of mean annual water-budget components, in inches, for the Island of Kauai, Hawaii. The water-budget components in the shapefile were computed by a water-budget model for a scenario representative of current conditions (2001-10 rainfall and 2001-10 land cover), as described in U.S. Geological Survey Scientific Inv
