Mean annual water-budget components for Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Maui, and the Island of Hawaiʻi for a set of recent and future climate conditions, and 2020 land cover The shapefiles in this dataset represent the spatial distribution of mean annual water-budget components, in inches, for Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Maui, and the Island of Hawaiʻi, for a set of recent and future climate conditions, and 2020 land cover. The four main 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 that span a range of future-climate conditions for each island. The three future-climate projections include (1) a mid-century scenario using projected rainfall conditions representative of phase 5 of the Coupled Model Intercomparison...

Four water-budget scenarios were developed to quantify the effects of drought on soil moisture, evapotranspiration, and climatic water deficit for each island as follows: (1) a reference condition, the Non-Drought scenario, consisting of rainfall conditions during 1990–97 and 2003–06 and 2020 land cover, (2) rainfall conditions representative of the driest periods during 1920–2012 and 2020 land cover, (3) rainfall conditions...

The data in this release were used in generalized least-squares (GLS ) regression analyses (Stedinger and Tasker, 1985) to generate equations used to predict annual exceedance probabilities (AEPs) at ungaged locations on streams in the study area (Ensminger and others, 2021). Flood-frequency analyses were conducted using annual peak-flow data from the 1877-2016 water years to estimate streamflows...

Results include reference evapotranspiration (ETo), actual evapotranspiration (ETa), irrigated areas, consumptive use, and effective precipitation for each HUC12. ETo and ETa were estimated using the operational Simplified Surface Energy Balance (SSEBop, Senay and others, 2013; Senay and others, 2020) model executed in the OpenET (Melton and others, 2021) web-based application implemented in Google Earth Engine. Results provided by OpenET/SSEBop were summarized to hydrologic response units (HRUs) in the National Hydrologic...

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...

Catch-basin cleaning and street cleaning are two commonly used Best Management Practices that could be modified to remove leaves and qualify for additional load-reduction credits. This Data Release contains four tab-delimited .txt files containing additional information about the study area, characteristics of municipal street solids, and load-reduction estimates from increased catch basin and street cleaning practices that are not available in the associated report. This Data Release also contains a compressed file, "EngBrk_ModelArchive.7z", which archives the model developed and used for the project. The four .txt table files are: (1) "VT_LU_data.txt",...
