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… 

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.

Field Evaluation of DRAINMOD 5.1 Under a Cold Climate: Simulation of Daily Midspan Water Table Depths and Drain Outflows 1

Abstract:  The hydrologic performance of DRAINMOD 5.1 was assessed for the southern Quebec region considering freezing/thawing conditions. A tile drained agricultural field in the Pike River

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 tile

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.

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 has

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 tile

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 was

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 in

Field-scale evaluation of phosphorus leaching in acid sandy soils receiving swine waste.

Monitoring P leaching in soils with a long-term history of waste application, relate soil solution P concentrations to soil P status, and quantify PLeaching losses found low P sorption in Blanton and Autryville soils.

Phosphorus losses in surface and subsurface runoff from a snowmelt event on an agricultural field in Quebec

Nitrogen Balance in and Export from an Agricultural Watershed

Surface water nitrate (NO 3 - ) pollution from agricultural production is well established, although few studies have linked field N budgets, NO 3 - loss in tile drained watersheds, and surface water

Distributed hydrological modeling of total dissolved phosphorus transport in an agricultural landscape, part II: dissolved phosphorus transport

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 evaluation

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 as

Forms and Concentration of Phosphorus in Drainage Water of Twenty-Seven Tile-Drained Soils

In most mineral soils, P leaching is rarely viewed as an important environmental issue. However, P accumulation and decreased P sorption capacities in surface horizons of long-term fertilized soils
