Kentland Farm Remote Sensing Experiment

The research team recently completed a week-long survey for the ONR beach trafficability project at Kentland Farms (https://www.vaes.vt.edu/college-farm.html), the college farm of Virginia Tech. Three different soil types were prepared in a variety of ways in order to look at how signatures detected by a variety of remote sensing techniques change for different densities and moisture contents. This included synthetic aperture radar (SAR) images collected with the help of Hans Graber at CSTARS (https://www.cstars.miami.edu/) and ground-based radar data collected by Heidi Wadman of the USACE-FRF in Duck, NC. The unit weight, moisture content, and surface roughness for each patch was measured, as well as deployments of the bluedrop. Tube samples were also collected and will be tested for shear strength, permeability, consolidation parameters, Atterberg limits, grain size, and specific gravity. Celso Castro-Bolinaga and Melody Thomas from NC State were also able to join the survey and bring the JET device to measure erodibility parameters of the three soils.A huge thank you to the staff of Kentland Farms for assisting in selecting and preparing the sites surveyed, the entire research team for their help with measurements and lab testing, Paul McBride for loaning us his truck for the week, Hans for assistance with scheduling the SAR imagery, Heidi for collecting the radar data, Celso and Melody for bringing the JET, and Dr. Stark’s mom Elizabeth for helping out with some of the measurements. Keep an eye out for future updates of results from the survey!
