The importance of threshold in alluvial river channel geometry and dynamics

Abstract: Many cities and settlements are organized around alluvial rivers, which are self-formed channels composed of gravel, sand and mud. Much of the time alluvial river channels are oversized, in that they could accommodate greater water flow; yet during extreme storms they are woefully undersized, and potentially catastrophic flooding can occur. Considering widely varying hydroclimates, sediment supply, geologic constraints and varying vegetation, it is not altogether obvious that rivers should achieve an average c… Show more

“…For the remote-sensing community, the distillation of hundreds of available spatial metrics for describing reach-scale properties may streamline workflows for describing and classifying channels over broad, geomorphically diverse regions (Kasprak et al, 2016;O'Brien et al, 2019). For the physics-based fluvial geomorphology community (e.g., Phillips and Jerolmack, 2016;Phillips et al, 2021), it would be useful to know which landscape properties are significant based on field observations and which may be ignored in order to prioritize key aspects of mechanistic theory to focus on.…”
