Development and Multi-Process Calibration for the Keauhou Aquifer in West Hawai‘i

Illustration of present day model calculated average-annual groundwater recharge at 20 m cell-size resolution. Inset map shows detail of 1) flow routing effects, seen as higher recharge squares at the bottom of drainage channels, 2) direct infiltration from leaking water lines, seen as linear zones of higher infiltration, and 3) MFR zones seen as larger patches of high- infiltration.
