The Hawai'i groundwater recharge tool

February 7, 2022

This article discusses the design and implementation of the Hawai’i Groundwater
Recharge Tool, an application for providing data and analyses of the impacts
of land-cover modifications and changes in precipitation on groundwater-recharge
rates for the island of O’ahu. This application uses simulation data based on a set of
29 land-cover types and 2 precipitation conditions to provide users with real-time
recharge calculations for interactively defined land-cover modifications. The tool provides
two visualizations, representing the land cover for the island and the resultant
groundwater-recharge rates, and a set of metrics indicating the changes to groundwater
recharge for relevant areas to present a set of easily interpretable outcomes based
on user-defined scenarios. Users have varying degrees of control over the granularity
of data input and output, allowing for the quick production of a roughly defined scenario,
or more precise land-cover definitions. These modifications can be exported for
further analysis. Heuristics are used to provide a responsive user interface and performant
integration with the database containing the full set of simulation data. This
tool is designed to provide user-friendly access to the information on the impacts of
land-cover and precipitation changes on groundwater-recharge rates needed to assist
in making data-driven decisions.
