Robert Dudley
Biography
Rob Dudley is a Hydrologist with the U.S. Geological Survey New England Water Science Center. His work in recent years 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.

Composition and Distribution of Streambed Sediments in the Penobscot River, Maine, May 1999
Sediment samples were collected and geophysical surveys were run along 50 miles of the Penobscot River, Maine, in the spring of 1999 to produce maps that describe the composition and distribution of streambed sediments for selected areas in the river channel. The objective of the sediment survey was to locate areas along the river where fine-...
Dudley, Robert W.; Giffen, Sarah E.Hydrologic data for the Eastland Woolen Mill Superfund Site, Penobscot County, Corinna, Maine, March through June 1999
Hydrologic data were collected at the Eastland Woolen Mill Superfund Site, Corinna, Maine, from March 19, 1999 through June 11, 1999 as part of a study to formulate a geologic characterization and conceptual model of this study area. Data-collection consisted of measurements of water-surface elevations at 7 surface-water sites and 20 wells.
Nielsen, Martha G.; Dudley, Robert W.; Parrish, Camille S.Evaluation 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...
Dudley, Robert W.; Hodgkins, Glenn A.; Mann, Alexander; Chisolm, JohnWater 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...
Dudley, Robert W.; Hodgkins, Glenn A.; Nielsen, Joseph P.Borehole Geophysical Data From Eastland Woolen Mill Superfund Site, Corinna, Maine, March 1999
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...
Hansen, Bruce P.; Nichols, William J.; Dudley, Robert W.Simulated 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...
Mack, Thomas J.; Dudley, Robert W.Streamflow Statistics for the Narraguagus River at Cherryfield, Maine
Streamflow data have been collected for the Narraguagus River from 1948 to the present (2000) at the U.S. Geological Survey (USGS) streamgaging station at Cherryfield, Maine. This report describes a study done by the USGS to determine streamflow statistics using the streamflow record at the Narraguagus River station for use in total water use...
Dudley, Robert W.; Nielsen, Joseph P.Riverbed-Sediment Mapping in the Edwards Dam Impoundment on the Kennebec River, Maine By Use of Geophysical Techniques
INTRODUCTION In July 1997, the Federal Energy Regulatory Commission (FERC) issued a Final Environmental Impact Statement recommending that the 162-year-old Edwards Dam on the Kennebec River in Augusta, Maine, be removed. The impoundment formed by Edwards Dam extends about 15 mi to the city of Waterville, near the confluence of the Sebasticook...
