    • Mean annual groundwater recharge rates for the Island of Hawaiʻi for historical and future drought conditions, and three land-cover conditions

    Metadata Updated: July 20, 2024

    This shapefile represents the spatial distribution of mean annual groundwater recharge, in inches, for the Island of Hawaiʻi, 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 during 2007–12 from Frazier and others (2016) adjusted for a Representative Concentration Pathway 8.5 2071–99 (RCP8.5 2071–99) projection from Elison Timm and others (2015). Monthly rainfall for historical and future drought conditions was disaggregated into daily values using daily rainfall during 2007–12 from Longman and others (2019). A 2020 land-cover map developed by Kāne and others (2024a, 2024b) was used to define the land-cover conditions and the model subareas. Conversion 1 land cover is a hypothetical land-cover condition in which roughly 50 percent of forest and shrubland areas within the cloud zone are converted to grassland. Conversion 2 land cover is a hypothetical land-cover condition in which 100 percent of forest and shrubland areas within the cloud zone are converted to grassland. Groundwater recharge for each model subarea was computed for each scenario using a water-budget model developed by Oki (2022). The shapefile attribute information associated with each subarea present an estimate of mean annual groundwater recharge, and select geographic and land-cover attributes. Brief descriptions of the groundwater recharge estimates and attributes are included in this metadata file. Refer to Mair and others (2024) for further details of the methods and sources used to determine groundwater recharge and the attributes.
