Reliable water quality models are needed to forecast the water quality consequences of different agricultural nutrient management scenarios. In this study, the Soil and Water Assessment Tool (SWAT), version 2000, was applied to simulate streamflow, riverine nitrate (NO(3)) export, crop yield, and watershed nitrogen (N) budgets in the upper Embarras River (UER) watershed in east-central Illinois, which has extensive maize-soybean cultivation, large N fertilizer input, and extensive tile drainage…

Modeling the impacts of agricultural best management practices on runoff, sediment, and crop yield in an agriculture-pasture intensive watershed
TLDR
It was found that contouring practice reduced surface runoff by more than 18% in both conservation tillage and no-till practices for all crops used in this modeling study, and can be used to provide useful information for stakeholders to prioritize ecologically sound and feasible BMPs at fields that are capable of reducing sediment yield while increasing crop yield.
Modeling the impacts of agricultural best management practices on runoff, sediment, and crop yield in an agriculture-pasture intensive watershed
Best management practices (BMPs) are commonly used to control sediment yields. In this study, we modeled the Fort Cobb Reservoir watershed located in southwestern Oklahoma, USA using the Soil and…
Agricultural Policy Environmental eXtender Simulation of Three Adjacent Row-Crop Watersheds in the Claypan Region.
TLDR
The replicated study indicates that APEX provides a convenient and efficient tool to evaluate long-term benefits of conservation practices and that the presence of grass waterways reduced annual total phosphorus loadings by 13 to 25%.
Daily nitrate losses: implication on long-term river quality in an intensive agricultural catchment of southwestern france.
TLDR
The performance of the Soil and Water Assessment Tool model was assessed in the 1110-km Save catchment in southwestern France for predicting water discharge and nitrate loads and concentrations at the catchment outlet, considering observed data set uncertainty.
Modeling water quality to improve agricultural practices and land management in a tunisian catchment using the soil and water assessment tool.
TLDR
The SWAT model allowed managers to have several options to improve the water quality in the Joumine watershed and predicted the timing of monthly peak flow values reasonably well, and induced a reduction in NO loads to the river.
Evaluating the SWAT model to predict streamflow, nitrate loadings and crop yields in a small agricultural catchment
Abstract. This study aimed to evaluate the applicability of the Soil and Water Assessment Tool (SWAT) to predict streamflow, nitrate loadings and crop yields for a small agricultural catchment in…
Modelling the Contribution of Land Use to Nitrate Yield from a Rural Catchment
The nutrient flow dynamics in rural landscapes are among the basic characteristics of landscape functioning. In this study, the ecohydrological model SWAT (Soil and Water Assessment Tool) was applied…
Modeling sediment and nitrogen export from a rural watershed in eastern Canada using the soil and water assessment tool.
TLDR
This evaluation of SWAT demonstrated that the model has the potential to be used as a decision support tool for agricultural watershed management in Nova Scotia.
Integrating multimedia models to assess nitrogen losses from the Mississippi River basin to the Gulf of Mexico
TLDR
This study describes and implements an integrated, multimedia, process-based system-level approach to estimating nitrogen (N) fate and transport in large river basins and demonstrates application of the Integrated Modeling System (IMS) to the Mississippi River basin (MRB) to simulate streamflow and dissolved N loadings to the Gulf of Mexico (GOM).

Timing of riverine export of nitrate and phosphorus from agricultural watersheds in Illinois: implications for reducing nutrient loading to the Mississippi River.
TLDR
A program of intensive, long-term monitoring allowed us to assess how nutrient export was distributed across the range of discharge that occurred at each site and to examine mechanistic differences between NO3(-)-N and DRP export from the watersheds and simple simulations showed that reducing in-stream nutrient loads by as much as 50% during periods of low discharge would not affect annual nutrient export fromThe Illinois watersheds.
