Characterization and Placement of Wetlands for Integrated Conservation Practice Planning

Abstract

ABSTRACT. Constructed wetlands have been recognized as an efficient and cost-effective conservation practice to protect

Evaluation of AnnAGNPS Wetland Nitrogen Removal Component on Farmed Prairie Potholes

“…For instance, Tomer et al (2013) investigated the nitrogen annual nitrogen loss rate from a watershed with several constructed wetlands. Momm et al (2016) also utilized AnnAGNPS to generate potential wetland locations and characterize wetland characteristics in the Big Bureau Creek watershed, located in north central Illinois. However, limited studies have investigated the AnnAGNPS AgWET nitrogen removal performance in regard to the field monitoring data, and to our knowledge, none have looked at prairie potholes.…”

Effects of land management on inundation of prairie pothole wetlands in the Des Moines Lobe using AnnAGNPS

“…AnnAGNPS is a watershed scale, continuous simulation, daily time step model. The GIS based wetland component of AnnAGNPS known as AgWET can be used for identifying and characterizing topographic depressions (puddles/potholes) during DEM preprocessing, which makes this model appropriate for investigation of the effect of different land management on pothole inundation (Momm et al, 2016). AnnAGNPS is well-suited to small scale watersheds, and is able to produce satisfactory hydrologic outputs for the Midwest United States (Richardson et al, 2008;Upadhyay et al, 2018;Yuan et al, 2011;Yuan et al, 2003).…”

Wetlands and Coastal Systems: Protecting and Restoring Valuable Ecosystems

“…The authors noted changes in vegetation following the removal of cattle from the region, highlighting the potential of the GEE to help engineers and managers better understand anthropogenic, or even natural, impacts on wetland systems. Momm et al (2016) provided a detailed description of AgWet, which is the new GIS-based wetland component of the USDA's AnnAGNPS (Annualized Agricultural NonPoint Source) pollutant loading model. AgWet allows users to identify potential wetland sites within a watershed and evaluate the ability of artificial or natural wetlands to reduce nutrient loads throughout the watershed.…”

“…Such capabilities allow users to examine scenarios to maximize NPS reductions while minimizing impacts to agricultural activities. Momm et al (2016) evaluated the capabilities of the AgWet component using a north-central Illinois watershed that was previously studied as part of a nutrient trading feasibility study for which artificial wetland locations were manually determined via field investigations and imagery analysis. The AgWet-determined wetlands were quite similar in size to the manually determined wetlands (R 2 = 0.95).…”
