John C. Hammond, PhD
John Hammond works as a Research Hydrologist for the USGS MD-DE-DC Water Science Center.
John studies hydroclimatic variability and trends, seasonal snow dynamics, empirical streamflow relationships across scales, and incorporates satellite data into hydrologic models. Current projects include improving snow process representation in hydrologic models, characterizing hydrologic drought, developing drought early warning systems, and drivers of non-perennial flow, and DC StreamStats.
I obtained my PhD in Watershed Science at Colorado State University in 2018 where I studied hydrologic change across the intermittent-persistent snow transition of the western U.S. is response to snow loss. This work assessed the effects of snow persistence on streamflow generation and soil moisture through a combination of remote sensing, surface station data analysis, hydrologic modeling, and geospatial statistics.
Research interests include:
- Runoff forecasting in snow-dominated watersheds
- Input partitioning through the critical zone
- Hydroclimatic and cryospheric trend detection
- Low-cost sensors for snow and streamflow monitoring
- Intermittent snow and streamflow occurrence and prediction
Consulting experience:
- Remote sensing of snow occurrence timing and distribution
- Flood innundation mapping
- Hydrologic and meteorologic equipment installation and maintenance
Science and Products
Drought Prediction Science
Drought is a prolonged and widespread deficit in available water supplies that creates multiple stressors across ecosystems and communities. The U.S. Geological Survey Water Mission Area conducts drought research and modeling to improve drought prediction capabilities. The research focus is on understanding the hydrological, ecological, and economic ramifications of drought. The modeling focus...
Surface Water Capabilities @ MD-DE-DC
As an integrated part of the WSC, the Surface Water Team monitors and conducts investigative research to describe and improve our region's understanding of extreme hydrologic events - droughts, floods and flood hazards, and coastal or bay storm surge and inundation. They also facilitate measurement of precipitation, streamflow, stage and computation of streamflow at locations in Maryland, Delaware...
