About Alexandra's research:
Stream restoration practitioners need ecological assessment approaches that are affordable, repeatable, objective, and logistically feasible to develop and apply science-based restoration techniques. In this work, ecological evaluation techniques using a consumer-grade drone, structure-from-motion photogrammetry, geographic information systems, and machine learning are developed and tested for stream restoration evaluation. The drone-based evaluation methods’ efficacy is compared to conventional evaluation and monitoring methods, including a detailed case study at the Sawyer Mill dam removal project (Dover, NH).
