Robert Dudley is a Supervisory Hydrologist in the New England Water Science Center.
As Chief of the Statistical and Geospatial Section, New England Water Science Center, Rob manages a diverse team of scientists involved in a wide range of interpretive water-resources investigations that include water use, quantity, and quality, geospatial applications, and remote sensing. His project work has focused on regional and national-scale statistical investigations of trends and variability of surface waters and groundwaters, and developing methods for estimating river flow using satellite imagery and altimetry data.

Generalized hydrogeologic framework and groundwater budget for a groundwater availability study for the glacial aquifer system of the United States Generalized hydrogeologic framework and groundwater budget for a groundwater availability study for the glacial aquifer system of the United States
The glacial aquifer system groundwater availability study seeks to quantify (1) the status of groundwater resources in the glacial aquifer system, (2) how these resources have changed over time, and (3) likely system response to future changes in anthropogenic and environmental conditions. The glacial aquifer system extends from Maine to Alaska, although the focus of this report is the...

Groundwater-level trends in the U.S. glacial aquifer system, 1964-2013 Groundwater-level trends in the U.S. glacial aquifer system, 1964-2013
The glacial aquifer system in the United States is a major source of water supply but previous work on historical groundwater trends across the system is lacking. Trends in annual minimum, mean, and maximum groundwater levels for 205 monitoring wells were analyzed across three regions of the system (East, Central, West Central) for four time periods: 1964-2013, 1974-2013, 1984-2013, and...

Forecasting the probability of future groundwater levels declining below specified low thresholds in the conterminous U.S. Forecasting the probability of future groundwater levels declining below specified low thresholds in the conterminous U.S.
We present a logistic regression approach for forecasting the probability of future groundwater levels declining or maintaining below specific groundwater-level thresholds. We tested our approach on 102 groundwater wells in different climatic regions and aquifers of the United States that are part of the U.S. Geological Survey Groundwater Climate Response Network. We evaluated the...

Trends in snowmelt-related streamflow timing in the conterminous United States Trends in snowmelt-related streamflow timing in the conterminous United States
Changes in snowmelt-related streamflow timing have implications for water availability and use as well as ecologically relevant shifts in streamflow. Historical trends in snowmelt-related streamflow timing (winter-spring center volume date, WSCVD) were computed for minimally disturbed river basins in the conterminous United States. WSCVD was computed by summing daily streamflow for a...

Regression Equations for Monthly and Annual Mean and Selected Percentile Streamflows for Ungaged Rivers in Maine Regression Equations for Monthly and Annual Mean and Selected Percentile Streamflows for Ungaged Rivers in Maine
In an effort to delineate hydrologic conditions in Maine, the U.S. Geological Survey, in cooperation with the Maine Department of Transportation, used streamflow data to develop dependent variables for 130 regression equations for estimating monthly and annual mean and 1, 5, 10, 25, 50, 75, 90, 95, and 99 percentile streamflows for ungaged, unregulated rivers in Maine. Daily streamflow...
