This raster dataset represents Oakland County's potential groundwater recharge areas. It was adapted (portion of Oakland County was clipped) from raster data obtained from the School of Natural Resources and Environment at the University of Michigan in October of 2004. Lower pixel values indicate groundwater recharge areas while higher values represent groundwater discharge areas. The dataset originated from a terrain-based approach for predicting groundwater delivery to streams and other surface water systems using mapped data within a GIS environment. The data is referred to as Darcy's Groundwater Recharge because the model used to develop it is based on the principals of Darcy's Law. Output was calculated in units of m day-1 for every 30 m2 grid cell across Lower Michigan.
