Nutrient Farming and Traditional Removal: An Economic Comparison By Donald L. Hey, J.A. Kostel, A. P. Hurter, and R. H. Kadlec. 2005. Water Environment Research Foundation, 58 pages. The project derived cost equations for nutrient removal using conventional wastewater technology and treatment wetlands. The project also created a nutrient removal model—and associated parameters—for treatment wetlands and demonstrated the savings in capital and operating costs that treatment wetlands can provide.
An Ecological Solution to the Flood Damage Problem. By Donald L. Hey, Jill Kostel, and Deanna Montgomery.In: Criss, R.E. and Kusky T. M. 2009. Finding the Balance between Floods, Flood Protection, and River Navigation, Saint Louis University, Center for Environmental Sciences.
*Flood Damage Reduction in the Upper Mississippi River Basin: An Ecological Means. TWI led a two-year study (2004-2006) to analyze data from 77 counties in the 100-year floodplain in Missouri, Iowa, Minnesota, Illinois and Wisconsin and identified 1.9 million acres that could be used to store emergency floodwaters. These areas are former or degraded wetlands or areas behind levees. Funded by McKnight Foundation.
The Wetlands Initiative is dedicated to restoring the wetland resources of the Midwest to improve water quality, increase wildlife habitat and biodiversity, and reduce flood damage.
