Dr. Mahoney's expertise lies in monitoring and modeling of hydrologic processes and water quality at the watershed scale. Dr. Mahoney focuses on investigating the provenance of non-point source pollutants, including soil and sediment, within stream networks. Dr. Mahoney also applies process-based hydrologic models to investigate the spatiotemporal variation in streamflow expansion and contraction in headwater stream networks. Dr. Mahoney lab in the W.S. Speed building contains equipment to discern the source, fate, and transport of sediment in watersheds and monitor stream discharge and water quality.
