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.

Flooding of the Androscoggin River during December 18-19, 2003, in Canton, Maine Flooding of the Androscoggin River during December 18-19, 2003, in Canton, Maine
The Androscoggin River flooded the town of Canton, Maine in December 2003, resulting in damage to and (or) evacuation of 44 homes. Streamflow records at the U.S. Geological Survey (USGS) streamflow-gaging stations at Rumford (USGS station identification number 01054500) and Auburn (01059000) were used to estimate the peak streamflow for the Androscoggin in the town of Canton for this...

This Fact Sheet is one in a series that highlights information or recent research findings from the USGS National Streamflow Information Program (NSIP). The investigations and scientific results reported in this series require a nationally consistent streamgaging network with stable long-term monitoring sites and a rigorous program of data quality assurance, management, archiving, and...

Water budget for Lake Auburn, Maine, May 1, 2000 through April 30, 2003 Water budget for Lake Auburn, Maine, May 1, 2000 through April 30, 2003
Annual water budgets were developed for Lake Auburn in southwestern Maine for three water-budget years, May 1, 2000 through April 30, 2003. The measured inflow components of the water budget are direct precipitation to the surface of the lake and surface-water inflow. Mean annual inflow (precipitation and surface water) to Lake Auburn during water-budget years 2001-03 was 816 million...

Hydraulic-Geometry Relations for Rivers in Coastal and Central Maine Hydraulic-Geometry Relations for Rivers in Coastal and Central Maine
Hydraulic-geometry relations (curves) were derived for 15 sites on 12 rivers in coastal and central Maine on the basis of site-specific (at-a-station) hydraulic-geometry relations and hydraulic models. At-a-station hydraulic-geometry curves, expressed as well-established power functions, describe the relations between channel geometry, velocity, and flow at a given point on a river. The...

Estimating Monthly, Annual, and Low 7-Day, 10-Year Streamflows for Ungaged Rivers in Maine Estimating Monthly, Annual, and Low 7-Day, 10-Year Streamflows for Ungaged Rivers in Maine
Regression equations to estimate monthly, annual, and low 7-day, 10-year (7Q10) streamflows were derived for rivers in Maine. The derived regression equations for estimating mean monthly, mean annual, median monthly, median annual, and low 7Q10 streamflows for ungaged rivers in Maine presented in this report supersede those derived in previous studies.

Historical Dates of Ice-Affected Flows for 18 Rivers in New England Historical Dates of Ice-Affected Flows for 18 Rivers in New England
Historical dates of ice-affected flows for 18 rivers in New England were compiled and are presented in this report. The length of this record for the rivers ranges from 48 to 71 years, with an average of 62 years. The minimum number of days of ice-affected flow in a water year (October 1 to September 30) ranged from zero on three rivers in south-coastal Maine and coastal New Hampshire to...

Historical trend in ice thickness on the Piscataquis River in central Maine. Historical trend in ice thickness on the Piscataquis River in central Maine.
We analyzed a long-term record of ice thickness on the Piscataquis River in central Maine to determine whether there were temporal trends that were associated with climate warming. Trends in ice thickness were compared and correlated with regional time series of winter air temperature, heating degree days (HDD) , date of river ice-out, seasonal center-of-volume date (SCVD) (date on which...

Trends in Streamflow, River Ice, and Snowpack for Coastal River Basins in Maine During the 20th Century Trends in Streamflow, River Ice, and Snowpack for Coastal River Basins in Maine During the 20th Century
Trends over the 20th Century were examined in streamflow, river ice, and snowpack for coastal river basins in Maine. Trends over time were tested in the timing and magnitude of seasonal river flows, the occurrence and duration of river ice, and changes in snowpack depth, equivalent water content, and density. Significant trends toward earlier spring peak flow and earlier center-of-volume...

Water budget for Sebago Lake, Maine, 1996-99 Water budget for Sebago Lake, Maine, 1996-99
Annual water budgets were developed for Sebago Lake in southwestern Maine. The inflow components of the water budget are direct precipitation to the surface of the lake and surface-water inflow. Mean annual inflow to Sebago Lake during water years 1996-99 was 35,100 million cubic feet. The outflow components of the water budget are evaporation from the surface of the lake, municipal...
