Florida Nature Conservancy
Designed and conducted computer simulations of groundwater flow using MODFLOW for evaluating the potential impact of proposed open-pit sand mining operations on nearby wetlands on the Nature Conservancy Tiger Creek Preserve in central Florida. This computer simulation incorporated results from an existing U.S. Geological Survey MODFLOW model as boundary conditions for a fine-grid model of the surficial aquifer where sand mining operations were proposed. These simulation results are being used for planning protection strategies for the Tiger Creek Preserve and for wetlands in similar hydrogeologic settings.

Arizona Nature Conservancy
Assisted with preparing successful Arizona Water Protection Fund grant applications by designing hydrogeological monitoring and aquifer characterization plans to investigate groundwater and surface water interaction at two Nature Conservancy properties in the Santa Cruz and San Pedro River valleys, Arizona. Managed the hydrogeologic aquifer characterization investigation, installation of monitoring piezometers, data collection, aquifer testing, computer simulation of groundwater pumping impacts on streamflow, and prepared the technical report summarizing the study results for the San Pedro River Preserve. The investigation at the San Pedro River Preserve was in support of a large re-vegetation project at the preserve.

Georgia Nature Conservancy
Updated the existing U.S. Geological Survey Regional Aquifer System Analysis MODFLOW groundwater flow model to current pumping conditions, and conducted simulations of potential future hydrologic conditions under projected groundwater pumping scenarios from the Floridan aquifer. A substantial fraction of river base-flow in the Altamaha River and other rivers in the region is supported by upward vertical leakage of groundwater from the Floridan aquifer to the surficial aquifer. This simulation evaluated potential changes in such vertical leakage and provided the basis for water management planning.
