TL;DR: In this paper, the authors combine the tools of evolutionary computation with a water quality model and cost data to develop a trade-off frontier for the Upper Mississippi River Basin specifying the least cost of achieving nutrient reductions and the location of the agricultural conservation practices needed.

TL;DR: In this article, the authors used the Soil and Water Assessment Tool model to assess changes in downstream flood risks under different land uses for the large, intensely agricultural, Raccoon River watershed in Iowa.

TL;DR: An integrated assessment model is developed linking the water quality effects of cropland conservation investment decisions on the more than 550 agricultural subwatersheds that deliver nutrients into the Gulf with a hypoxic zone model and suggests that by targeting croplands conservation investments to the most cost-effective location and extent of coverage, the Action Plan goal of 5,000 km2 can be achieved.

TL;DR: In this article, the authors outline a methodology to simultaneously assess economic costs and water quality benefits associated with the hypothetical placement of a broad set of conservation practices, including land set-aside, terraces, grassed waterways, contouring, conservation tillage, and a simple nutrient reduction strategy.

TL;DR: In this paper, an integrated modeling system has been constructed with the hydrologic Soil and Water Assessment Tool (SWAT) model, capable of estimating river basin responses to alternative cropping and/or management strategies.
