John C Hammond, PhD

John is a Hydrologist with the USGS.  His research focuses on hydroclimatic variability and trends, identifying emprical streamflow relationships across gage networks, and incorporating remotely sensed data into hydrologic models. Current projects include extending NHM-PRMS to Alaska, updating Delaware flood-frequency relationships, and examining low flow variability in the Delaware River Basin.
