Paper Abstract

Remote sensing technologies are used to collect data that measure properties of materials that comprise the earth's surface, subsurface, and man-made features such as levees constructed of these materials. Scientists use, manipulate, and analyze these data to make inferences about levee materials as well as identify local areas where intensive field investigation resources might most efficiently be spent. In this current study, airborne LiDAR and electromagnetic (EM) conductivity data have been processed and integrated with other digital data to identify specific areas within a levee system where anomalies exist. Preliminary results support the idea that changes in material type and the presence of man-made, levee-perforating structures do cause recognizable effects on recorded EM conductivities. Planned site investigations at identified EM anomalous areas will focus the efforts of field crews to determine the causes and significance of anomalies. As the field season progresses and data from in situ testing of levee materials are analyzed, relationships between material types and the EM data will be represented in graphics. Results of the study will be used to calibrate a model with which levee systems can be assessed for compliance with certain design specifications as well as predicting performance during flood events.
