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 recent conditions (1978–2007 rainfall and 2010 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 data set, consisting of 400,714 subareas (polygons), was generated using Esri ArcGIS software by intersecting (merging) multiple spatial data sets. Spatial datasets merged include those that characterize...

A three-dimensional, groundwater model (SUTRA) was developed to understand the effects of seawater washover on the freshwater lens of Roi-Namur, Kwajalein Atoll, Republic of the Marshall Islands. The model was calibrated by using observation data collected from 1990 through 1991 and 2008 through 2010. This USGS data release contains all of the input and output files for the simulations described in the associated journal article "Seawater-flooding events and impact on freshwater lenses of low-lying islands: controlling factors, basic management and mitigation" by Stephen B. Gingerich, Clifford I. Voss, and Adam G. Johnson, Journal of Hydrology (https://doi.org/10.1016/j.jhydrol.2017.03.001). This data release also...

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 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...

The zipped folder (Monthly_water_budget_Roi-Namur_2000-12.zip) associated with this metadata file contains 156 polygon shapefiles. Collectively, the 156 shapefiles contain spatially distributed estimates of groundwater recharge and other water-budget components, in inches, for Roi-Namur, Kwajalein Atoll, Republic of the Marshall Islands, for each month and year during 2000–12. The name of each shapefile indicates the year and month of the water-budget components contained in the shapefile. The month-year estimates of recharge and other water-budget components summarized in each shapefile were summed from daily water-budget components that were computed using a water-budget model. The equations of the water-budget...
