Remote Sensing as a Tool for Analysing Channel Dynamics and Geomorphic Effects of Floods

Over the past two decades, the use of optical remote sensing in fluvial geomorphology has become widely employed for several applications, due to improvements in geospatial technologies and data availability. However, applications focused on change detection of channel dynamics and geomorphic response to individual flood events are still relatively rare. Insights into the complexity of interactions driving geomorphic changes might be obtained by application of diverse remote sensing approaches, depending on several factors (e.g. temporal and spatial resolution, magnitude of detected change). An overview about remote sensing as a tool for channel dynamics and geomorphic response to flood detection is illustrated, including discussion about advantages and limitations of optical remote sensing.
