Douglas A Burns
Doug is a Research Hydrologist currently working as the Coordinator of the Delaware River Basin Next Generation Water Observing System (NGWOS).
Doug holds an M.S. in Environmental Sciences from the Univ. of Virginia, and a Ph.D. in Water Resources Management from the State Univ. of New York, College of Environmental Science and Forestry. His disciplinary background is primarily in biogeochemistry and hydrology with a focus on understanding the processes that control the cycling of chemical elements through watersheds and ecosystems. An emphasis on the cycling of atmopsheric pollutants and their environmental effects is noteworthy. He has worked as a Research Hydrologist in the New York Water Science Center since 1987 on studies that include the effects of acid rain on ecosystems, the cycling of nitrogen in watersheds, and environmental mercury cycling. His investigations have also included the environmental effects of landscape disturbance such as suburban land use, climate change, and forest harvesting. A recent interest is studying the effects of ongoing and future climate change on streamflow, with an emphasis on high flows. He works collaboratively, often with several investigators from the USGS, and other agencies and universities. Study approaches applied include monitoring of water and soil chemistry, quantifying the rates of key cycling processes, experimental manipulations of landscapes, use of natural and applied isotope tracers, and statistical and process-level models. He is also active in professional societies, has organized conferences at regional, national, and international levels, and has served in leadership roles in many organizations and agencies. Other activities include chairing a proposal evaluation panel for a federal agency, working at the science-policy interface by serving as Director of the National Acid Precipitation Assessment Program, and serving on an EPA Clean Air Act Advisory Panel, as well as serving on program evaluation and advisory panels for several agencies and science organizations.

Analysis of δ15N and δ18O to differentiate NO3− sources in runoff at two watersheds in the Catskill Mountains of New York
To quantify the movement of atmospheric nitrogen deposition through two forested watersheds in the Catskill Mountains of New York, dual‐isotope analysis (δ15N and δ18O) was used to differentiate NO3− derived from precipitation from NO3− derived by microbial nitrification and to quantify the contributions of these sources to NO3− in drainage waters.

Burns, Carol KendallThe effects of atmospheric nitrogen deposition in the Rocky Mountains of Colorado and southern Wyoming— A synthesis and critical assessment of published results
The Rocky Mountain region of Colorado and southern Wyoming receives as much as 7 kilograms per hectare per year ((kg/ha)/yr) of atmospheric nitrogen (N) deposition, an amount that may have caused changes in aquatic and terrestrial life in otherwise pristine ecosystems.

The Neversink Watershed Study was initiated in 1991 to develop an understanding of the key natural processes that control water quality within the forested, 166 km 2 (64 mi 2), Neversink River watershed; part of the New York City drinking water supply system, in the Catskill Mountain region of New York.

The geographic sources and hydrologic flow paths of stormflow in small catchments are not well understood because of limitations in sampling methods and insufficient resolution of potential end members. To address these limitations, an extensive hydrologic dataset was collected at a 10 ha catchment at Panola Mountain research watershed near Atlanta, GA, to quantify the contribution of three geograAuthorsDouglas A.

Forested headwater streams in the Catskill Mountains of New York show significant among-catchment variability in mean annual nitrate (NO3-) concentrations. Large contributions from deep groundwater with high NO3- concentrations have been invoked to explain high NO3- concentrations in stream water during the growing season. To determine whether variable contributions of groundwater could explain amAuthorsA.J. West, S.E.G. Findlay, Douglas A. Burns, K.C. Weathers, Gary M. LovettTopographic controls on the chemistry of subsurface stormflow
Models are needed that describe how topography and other watershed characteristics affect the chemical composition of runoff waters, yet little spatially distributed data exist to develop such models. A topographically driven flushing mechanism for nitrate (NO3-) and dissolved organic carbon has been described in recent literature; however, this mechanism has not yet been thoroughly tested.

Despite a decreasing trend in acidic deposition rates over the past two to three decades, acidified surface waters in the northeastern United States have shown minimal changes. Depletion of soil Ca pools has been suggested as a cause, although changes in soil Ca pools have not been directly related to long-term records of stream chemistry. To investigate this problem, a comprehensive watershed stuAuthorsG. B. Lawrence, Mark B. David, Gary M. Lovett, Peter S. Murdoch, Douglas A. Burns, John L. Stoddard, Barry P. Baldigo, J.H.

Seven nested headwater catchments (8 to 161 ha) were monitored during five summer rain events to evaluate storm runoff components and the effect of catchment size on water sources. Two-component isotopic hydrograph separation showed that event-water contributions near the time of peakflow ranged from 49% to 62% in the 7 catchments during the highest intensity event.

End-member mixing analysis has been used to determine the hydrological structure for basin hydrochemical models at several catchments. Implicit in this use is the assumption that controlling end members have been identified, and that these end members represent distinct landscape locations. At the Panola Mountain Research Watershed, the choice of controlling end members was supported when a largeAuthorsR. P. Hooper, Brent T. Aulenbach, Douglas A. Burns, J. McDonnell, J. Freer, C.

Abrupt increases and decreases in mean seasonal and annual stream NO3- concentrations during the period of record (1983-1995) at Biscuit Brook, a headwater stream in the Catskill Mountains of New York, have provided an opportunity to study the biogeochemical processes that control NO3- movement through forested watersheds.

Groundwater and stream water data collected at three headwater catchments in the Neversink River watershed indicate that base flow is sustained by groundwater from two sources: a shallow flow system within the till and soil and a deep flow system within bedrock fractures and bedding planes that discharges as perennial springs.
