Abstract:The main goal of this study is to develop a rapid technique for mapping and assessing erodibility and internal erosion damage. The research objectives include: (1) identify levees where sand boils, seepage damage, or erosion damage are present, (2) conduct laboratory tests on benchmark samples and samples retrieved from levees to define relationships between soil type, erodibility, and resistivity, (3) measure resistivity and shear wave velocity in the field and map internal damage using the relationships defined, (4) evaluate erosion predictions by comparing mapped damage with visible distress signs and collect samples to confirm these predictions (when possible).
