Monitoring of Streambank Erosion using UAS and Lidar

Streambank erosion is estimated to account for 30-80% of sediment loading into waterways. In many cases, this sediment is carrying important pollutants, such as phosphorus. Recent developments in UAS-based photogrammetry provide opportunities for rapidly and economically determining streambank erosion and deposition at variable scales.

This study aims to evaluate the effectiveness and capabilities of UAS to measure streambank erosion. An UAS and terrestrial laser scanner are used to capture fine-scale topographic data of various types of streambanks and qnatify the change over time. UVM Spatial Analysis lab contributes to the fieldwork effort of mapping with UAS in the Mad River and Winooski River watersheds in Vermont.
