Vashan Wright checks sand trap at his study site

A Sand Transport Rate Model and Michigan Dunes

Mentor/Investigator: Vanshan Wright
Partnered with students from Physics 133

Project Description (from poster abstract): Mathematical models are useful for predicting real-world phenomena, but can a sand transport model help researchers understand processes on Lake Michigan dunes?  This study investigates predicted and actual sand transport rates at a beach site in P.J Hoffmaster State Park, Michigan. In November 2011, actual sand transport rates were measured using Leatherman sand-traps employed for thirty-minute periods. Wind data were collected with an anemometer array at the study area; surface conditions were also recorded, including fetch distance and surface moisture content. Predicted sand transport rates were calculated using Hsu’s mathematical model and wind data collected at the field site. When compared to field measurements, Hsu’s model tends to over-predict sand transport rate. Investigating models might be a helpful way to simplify and understand what is going on at Lake Michigan coastal dunes. Abstract (pdf)
