Master of Science Mark Eastman Bioresource Engineering Field-Scale Nutrient Transport Monitoring and Modeling of Subsurface and Naturally Drained Agricultural Lands Eutrophication impacts the quality of many surface waters worldwide. Algal blooms threaten lake water quality and in order to control their growth, understanding of nutrient transport at the field-scale is essential. In order to accomplish this, a combination of field monitoring and computer modeling with the SWAT model was… Expand
Comparative evaluation of phosphorus losses from subsurface and naturally drained agricultural fields in the Pike River watershed of Quebec, Canada
Phosphorus (P) is the limiting nutrient responsible for the development of algal blooms in freshwater bodies, adversely impacting the water quality of downstream lakes and rivers. Since agricultureExpand
Modeling the influence of tile drainage flow and tile spacing on phosphorus losses from two agricultural fields in southern Québec
Tile drainage is a widely adopted water management practice in the eastern Canadian provinces of Quebec and Ontario. It aims to improve the productivity of poorly drained agricultural fields.Expand
Phosphorus reduction from agricultural runoff in a pilot-scale surface-flow constructed wetland
Abstract Excess P in surface waters in Quebec is the primary cause of water quality deterioration and the majority of it is coming from agricultural land as non-point source pollution. The objectiveExpand
Modeling agricultural land drainage under spring snowmelt conditions with DRAINMOD
There are few computer models that can simulate winter freeze–thaw conditions and spring snowmelt hydrology for agricultural tile drained lands. DRAINMOD, which is used widely to simulate tileExpand
Modelling climate change impacts on the hydrology of an agricultural watershed in southern Québec
Spring flooding and water availability during the summer are two major concerns in southern Québec. Climate change is expected to further exacerbate shortages of fresh water resources in Québec.Expand

PHOSPHORUS LOSSES IN SURFACE RUNOFF AND SUBSURFACE DRAINAGE WATERS ON TWO AGRICULTURAL FIELDS IN QUEBEC
Concentrations of phosphorus (P) above the water quality guideline of 0.03 mg L-1 are commonly found in rivers draining agricultural lands in Quebec. This gives rise to eutrophication, which hasExpand
Hydrological and water quality modeling of agricultural fields in Quebec
Two tile-drained agricultural fields in the Pike River watershed of Southern Quebec were instrumented in October 2000 to monitor phosphorus and nitrate concentrations in surface runoff and tileExpand
Water Quality Modeling of Two Agricultural Fields in Southern Quebec Using SWAT
To study the dynamics of nutrient transport at the field scale, we collected data from two tile-drained agricultural fields in the Pike River watershed of southern Quebec. A two-year data set wasExpand
Phosphorus loss in agricultural drainage: historical perspective and current research
The importance of P originating from agricultural sources to the nonpoint source pollution of surface waters has been an environmental issue for decades because of the well-known role of P inExpand

Abstract. Reducing non-point source phosphorus (P) loss to drinking water reservoirs is a main concern for New York City watershed planners, and modeling of P transport can assist in the evaluationExpand
Agricultural Phosphorus and Eutrophication: A Symposium Overview
Phosphorus in runoff from agricultural land is an important component of nonpoint-source pollution and can accelerate eutrophication of lakes and streams. Long-term land application of P asExpand
