Matthew Miller


Matt Miller is a Research Hydrologist with the Utah Water Science Center in Salt Lake City, Utah.  His current research focuses on developing new approaches for interpreting large data sets to quantify the relationships between water quality, hydrology, land use, and climate at watershed and regional spatial scales.  Matt also studies how natural and anthropogenic activities influence aquatic biota.  Current projects include quantifying the baseflow component of streamflow in the Upper Colorado River Basin, factors affecting seasonal variability in watershed-scale nitrogen loss in the Chesapeake Bay Watershed, and using continuously collected water quality data to better understand temporal variation in biologic productivity.
