Biography
My work experience with the USGS includes investigation of climate-related hydrologic trends, watershed rainfall-runoff modeling, hydraulic modeling, statistical modeling, eco-hydrologic assessments, riverine and lacustrine sediment mapping, and public-water-supply water budgets. Ongoing and recent work includes: documenting historical long-term trends and modeling of future climate-related changes in streamflow and groundwater; development of national streamflow and groundwater climate change indicators in cooperation with USEPA; investigation of statistical methods for forecasting groundwater levels in the U.S.; investigation of trends in low flows and flood flows across the U.S.; and researching methods for computing river flows using satellite imagery and altimetry data.

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...

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-...

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.

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...

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...

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...

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...

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...
