These shapefiles represent the spatial distribution of mean annual groundwater recharge, in inches, for Kauaʻi, Oʻahu, Molokaʻi, Maui, and the Island of Hawaiʻi for a set of water-budget scenarios that characterize unique combinations of drought and land-cover conditions. Two water-budget scenarios were developed to quantify the effects of severe drought and future climate conditions on groundwater recharge for each island as follows: (1) rainfall conditions representative of the driest conditions during 1920–2012 and 2020 land cover, and (2) rainfall conditions representative of the driest conditions during a future dry-climate condition and 2020 land cover. Each drought condition was combined with two hypothetical...

This shapefile represents the spatial distribution of mean annual water-budget components, in inches, for the Island of Maui, Hawaii. The water-budget components in the shapefile were computed by a water-budget model for a scenario representative of predevelopment conditions (1978–2007 rainfall and 1870 land cover), as described in USGS Scientific Investigations Report (SIR) 2015-5164. The model was developed for estimating groundwater recharge and other water-budget components for each subarea of the model. The model-subarea dataset, consisting of 318,429 subareas (polygons), was generated using Esri ArcGIS software by intersecting (merging) multiple spatial datasets. Spatial datasets merged include those that...
This shapefile represents the spatial distribution of mean annual water-budget components, in inches, for Kauaʻi, Hawaiʻi for a 2020 land-cover and a set of four climate scenarios. The four climate scenarios used in the water-budget analyses include a reference climate scenario representative of recent conditions during 1978–2007, hereinafter the 1978–2007 scenario, and three downscaled future-climate projections. The three future-climate projections include (1) a mid-century scenario using projected rainfall conditions representative of phase 5 of the Coupled Model Intercomparison Project (CMIP5) Representative Concentration Pathway 8.5 (RCP8.5) 2041–71 scenario climate described in Elison Timm and others (2015),...
This shapefile represents the spatial distribution of mean annual water-budget components, in inches, for the Island of Oahu, 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 USGS Scientific Investigations Report (USGS SIR) 2015-5164. The model was developed for estimating groundwater recharge and other water-budget components for each subarea of the model. The model-subarea dataset, consisting of 395,955 subareas (polygons), was generated using Esri ArcGIS software by intersecting (merging) multiple spatial datasets. Spatial datasets merged include those that characterize...
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. This shapefile contains the boundaries of the moisture zones and boundaries of the model subareas that were used in the model simulations for Maui. The shapefile attributes include the names of the land-cover types assigned to model subareas and the mean annual recharge values determined for the model subareas for the baseline scenario of the sensitivity...

This shapefile represents the spatial distribution of mean annual groundwater recharge, in inches, for Maui, Hawaiʻi for a set of drought and land-cover conditions represented in six water-budget scenarios. The six scenarios include: (1) historical drought rainfall and 2020 land cover, (2) future drought rainfall and 2020 land cover, (3) historical drought rainfall and Conversion 1 land cover, (4) future drought rainfall and Conversion 1 land cover, (5) historical drought rainfall and Conversion 2 land cover, and (6) future drought rainfall and Conversion 2 land cover. Historical drought rainfall is monthly rainfall during 2007–12 from Frazier and others (2016), whereas future drought rainfall is monthly rainfall...
This shapefile 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 Investigations Report (USGS SIR) 2015-5164. The model was developed for estimating groundwater recharge and other water-budget components for each subarea of the model. The model-subarea dataset, consisting of 400,714 subareas (polygons), was generated using Esri ArcGIS software by intersecting (merging) multiple spatial datasets. Spatial datasets merged include...
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 scenario. The recharge distributions were estimated as part of a larger effort (Gingerich and others, 2019) to evaluate how one set of climate projections may impact Guam’s future groundwater resources. The recharge estimates may be used in numerical groundwater models that can evaluate the collective impacts of changes in recharge,...
This shapefile represents the spatial distribution of mean annual water-budget components, in inches, for the island of Oahu, Hawaii for a projected future-climate condition representative of phase 5 of the Coupled Model Intercomparison Project (CMIP5) Representative Concentration Pathway 8.5 (RCP8.5) 2041-70 scenario climate and 2010 land cover, as described in USGS Professional Paper (PP) 1876 by Izuka and Rotzoll (2023). The water-budget components for each model subarea were computed for the future-climate condition and 2010 land cover using a water-budget model developed by Engott and others (2017). The 2010 land-cover map developed by Engott (2017) was used to define the land-cover conditions and the model...

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 using a water-budget model developed by Johnson and others (2018). The 2017 land-cover map developed by Mair (2018) was used to define the land-cover conditions and the model subareas. The shapefile attribute information associated with each subarea (or polygon) present an estimate of mean annual rainfall, fog interception, irrigation,...
