Mean annual water-budget components for the Island of Maui, Hawaii, for a set of eight future climate and land-cover scenarios
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 representati

The FVR_2016_historic_future folder contains the input files needed to run the Fena Valley Reservoir water-balance model for the historic and future periods and a README_FVR_2016_historic_future.txt document that describes the contents of this folder and how to execute the water-balance model (https://doi.org/10.5066/F7HH6HV4) with the historic...
Southern Guam watershed model input files for historic (1990‒2009) and future (2080‒2099) climate conditions
The PRMS_2016_historic_future folder contains the climate by HRU files (CBH_files folder) needed to drive each of the modeled regions in southern Guam for the historic and future periods and a README_PRMS_2016_historic_future.txt document that describes the contents of this folder and how to update the previously published model files (https://doi.org...
Summary of soil field-saturated hydraulic conductivity, hydrophobicity, preferential-flow, and particle-size measurements collected at four study sites on the island of Maui, Hawaii, September 2017–August 2018
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 determining how infiltration rates and soil hydrophobicity are dependent on plant species type within forested areas on the islan...
Summary of soil field-saturated hydraulic conductivity, hydrophobicity, and preferential-flow measurements and soil laboratory-testing results collected at three sites on the islands of Maui and Hawaii, Hawaii, July 2016–January 2018
This data release contains soil-properties for one site (Nakula) on the Island of Maui and two sites (Nahuku and Lapahoehoe) on the Island of Hawaii. Maps showing the site locations are included in one of this dataset’s files (Study_sites_summary.pdf). The soil properties were compiled into three files, each formatted with comma-separated values. Field-saturated hydraulic co

Mean annual water-budget components for the Island of Maui, Hawaii, for projected climate conditions, CMIP3 A1B 2080-99 scenario climate and 2017 land cover
This shapefile represents the spatial distribution of mean annual water-budget components, in inches, for the Island of Maui, Hawaii for a projected climate condition representative of phase 3 of the Coupled Model Intercomparison Project (CMIP3) A1B 2080-99 scenario climate and 2017 land cover, as described in USGS SIR 2019-5064. The water-budget components for each model subarea were
Mean annual water-budget components for the Island of Maui, Hawaii, for average climate conditions, 1978-2007 rainfall and 2017 land cover
This shapefile represents the spatial distribution of mean annual water-budget components, in inches, for the Island of Maui, Hawaii for an average (or present-day) climate condition and 2017 land cover, as described in USGS SIR 2019-5064. The water-budget components for each model subarea were computed for a scenario representative of present-day climate conditions during 1978-2007 u
