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 water-resources investigations that encompass geomorphology, geospatial data management and modeling, water use and quantity investigations, water quality modeling, and remote sensing. His project work has focused on regional and national-scale statistical investigations of climate-related trends and variability of surface waters and groundwaters, probabilistic forecasting, and developing methods for computing river flows using satellite imagery and altimetry data.

Historical trend in ice thickness on the Piscataquis river, near Dover-Foxcroft, central Maine
No abstract available.AuthorsThomas G. Huntington, Glenn A. Hodgkins, Robert W. DudleyWater 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 cubic feet.AuthorsRobert W. DudleyHydraulic-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 derived atAuthorsRobert W. DudleyEstimating 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 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 110 on thAuthorsGlenn A. Hodgkins, James M. Caldwell, Robert W. DudleyHistorical 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 half of tAuthorsThomas G. Huntington, Robert W. Dudley, Glenn A. HodgkinsTrends 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 runoff daAuthorsRobert W. Dudley, Glenn A. HodgkinsEvaluation of the Effects of Development on Peak-Flow Hydrographs for Collyer Brook, Maine
The development of former agricultural or forested lands creates more impervious areas and drainage improvements that can increase the volume of runoff and decrease infiltration and ground-water recharge in a watershed. Drainage improvements also can improve the conveyance of runoff, decreasing the time of rise to peak flow between the start of a rainfall event and the peak surface-water runoff, aAuthorsRobert W. Dudley, Glenn A. Hodgkins, Alexander Mann, John ChisolmWater 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 water-supply wAuthorsRobert W. Dudley, Glenn A. Hodgkins, Joseph P. NielsenSimulated Ground-Water-Flow Responses to Geohydrologic Characteristics, Corinna, Maine
Ground-water-flow simulations of an idealization of surficial and bedrock aquifers of the East Branch Sebasticook River Valley, in Corinna, Maine, were done to test the effects of known or hypothesized geohydrologic characteristics on the local and regional ground-water-flow system. The purpose of the simulations was to develop a better understanding of the aquifer system to aid in planning for thAuthorsThomas J. Mack, Robert W.

Borehole-geophysical data were collected in cooperation with the U.S. Environmental Protection Agency in seven bedrock wells at the Eastland Woolen Mill Superfund site, Penobscot County, Corinna, Maine, in March, 1999. The data were collected as part of a reconnaissance investigation to provide information needed to address concerns about the distribution and fate of contaminants in ground-AuthorsBruce P.
