Summary
These shapefiles represent the spatial distribution of mean annual water-budget components, in inches, for the Island of Maui, Hawaii for a set of eight future climate and land-cover scenarios. The future climate conditions used in the water-budget analyses were derived from two end-of-century downscaled climate projections including (1) a projected future climate condition representative of phase 3 of the Coupled Model Intercomparison Project (CMIP3) A1B 2080-99 scenario climate described in Zhang and others (2016a, 2016b) and (2) a projected future climate condition representative of phase 5 of the Coupled Model Intercomparison Project (CMIP5) Representative Concentration Pathway 8.5 (RCP8.5) 2080-99 scenario climate described in [...]
Summary
These shapefiles represent the spatial distribution of mean annual water-budget components, in inches, for the Island of Maui, Hawaii for a set of eight future climate and land-cover scenarios. The future climate conditions used in the water-budget analyses were derived from two end-of-century downscaled climate projections including (1) a projected future climate condition representative of phase 3 of the Coupled Model Intercomparison Project (CMIP3) A1B 2080-99 scenario climate described in Zhang and others (2016a, 2016b) and (2) a projected future climate condition representative of phase 5 of the Coupled Model Intercomparison Project (CMIP5) Representative Concentration Pathway 8.5 (RCP8.5) 2080-99 scenario climate described in Elison Timm and others (2015). The four future land-cover scenarios developed by Brewington (2018) were used to define the land-cover conditions and model subareas. A unique set of water-budget components for each model subarea was computed for each combination of projected climate conditions and future land-cover using a water-budget model developed by Johnson and others (2018) and later modified by Mair and others (2019). The shapefile attribute information associated with each subarea (or polygon) present an estimate of mean annual rainfall, fog interception, irrigation, septic system leachate, seepage from reservoirs and cesspools, runoff, canopy evaporation, total evapotranspiration, and total recharge. These shapefiles also include select geographic and land-cover attributes of the model subareas. Brief descriptions of the water-budget components and attributes are included in this metadata file. Refer to Mair and others (2019) and Brewington and others (2019) for further details of the methods and sources used to determine these components and attributes.

The water-budget components in these shapefiles were determined as part of a study to estimate the spatial distribution of groundwater recharge on the Island of Maui, Hawaii, for a set of future climate and land-cover conditions, as described in Brewington and others (2019). 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 Maui.
