David S. McGraw

Assistant Research Scientist Hydrology

Professional Interests

Mr. McGraw's research interests include modeling surface water and groundwater systems with regard to water quality and quantity. Recent projects include: an investigation of the near-stream unsaturated zone during warm-season rain events for a small, sub-alpine stream; a groundwater model used to determine the source of stream quality degradation for the Lower Truckee River; water quality assessment and modeling of the California portion of the Truckee River Basin; suspended sediment analysis of the middle Truckee River; and quality assurance of monitoring activities in Alpine County, California.

Research Areas

  • Hydrology of the Unsaturated Zone
  • Contaminant Transport
  • Hydrogeological Controls on Availability and Quality of Ground Water
  • Integrated Watershed Systems
