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.

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...

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,...

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...

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-...

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...

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-...

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-...
