Potential particulate emissions by wind erosion from the indiana harbor confined disposal facility. Oral presentation at the Biological and Agricultural Engineering seminar, Kansas State University; Manhattan, Kansas. April 22, 2004. Interpretive Summary: Oral Presentation Technical Abstract: An Indiana Harbor Confined Disposal Facility (CDF) located in East Chicago, Indiana with a total area of about 140 acres is being designed by the U.S. Army Corp of Engineers. The CDF will contain contaminated sediments dredged from Indiana harbor ship canal. As part of the design process, analyses are needed on potential particulate emissions to support required operational assessments for the CDF. However, little is known about the changes in wind erodibility of the dredged sediments as they dry. Hence, small outdoor sediment bins were constructed at Manhattan, Kansas and filled with Indiana Harbor sediments. Sediment characteristics related to wind erodibility were then measured during the last 4 ½ months of 2003. This report briefly summarizes measurements of sediment wind erodibility and their application in simulating CDF particulate emissions using the Wind Erosion Prediction System (WEPS) model. The erodibility measurements included dispersed size distribution of primary particles, aggregate size distribution, water retention characteristics, water drop penetration tests, dry stability of aggregates/crust, loose erodible mass on the crust, and coefficient of linear extensibility. The measured texture of the sediment was a sandy loam, and it developed significant aggregation and shrinkage cracks upon drying. During the initial test period, oil, grease, and perhaps other contaminants made the aggregates/crust somewhat water repellent and thus, more resistant to breakdown by weathering forces than a typical sandy loam soil. |
