There is interest in developing small unmanned aerial system (UAS <25 kg) applications to improve spatial monitoring of dredge operations. UAS technologies offer a more viable and flexible alternative to conventional platforms such as satellites and manned aircraft. UASs fly at lower elevations and are capable of collecting imagery with high spatial and temporal resolution (e.g., 5 cm/pixel, 10 min revisit time); therefore, this technology can compete with traditional mapping solutions. This study demonstrated relatively uniform turbidity levels can be differentiated using high-resolution ground images on the centimeter scale calibrated to in situ water samples. Images are of turbidity near the water surface thus this application would be most appropriate for assessing turbidity near the surface or in shallow water habitats, relevant to, for example, sea grass beds and coral reefs. This approach will help produce evidence-based information about the dredge plume’s scale to help engage the process of leveraging better-informed water quality regulations and dredging strategies.
