Summary

This shapefile represents the spatial distribution of mean annual water-budget components, in inches, for Molokaʻi, 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), hereinafter the [...]

Purpose

The water-budget components in this shapefile were determined as part of a study to estimate the spatial distribution of groundwater recharge on Molokaʻi, Hawaiʻi, for a 2020 land-cover and a set of four climate scenarios, as described in Kāne and others (2024). The recharge estimates may be used in numerical groundwater models that can evaluate the effects of groundwater withdrawals on groundwater levels, streamflow, coastal discharge, and salinities in public and private wells on Molokaʻi, Hawaiʻi.
