Abstract Shallow coastal regions are among the fastest evolving landscapes but notoriously difficult to measure with high spatiotemporal resolution. Using Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) data, we demonstrate that signal‐to‐noise L band synthetic aperture radar (SAR) can reveal subaqueous channel networks at distal ends of river deltas. 27 UAVSAR images collected between 2009 and 2015 from Wax Lake Delta in Louisiana, USA, show under normal tidal conditions,...
Abstract We show that distributary channels on river deltas exhibit a mean bifurcation angle can be understood using theory developed in tributary channel networks. In certain cases, network geometries have been demonstrated to controlled by diffusive groundwater flow feeding incipient bifurcations, producing characteristic of 72 ∘ . measured 25 unique bifurcations an experimental delta and 197 10 natural deltas, yielding 70.4 ±2.6 (95% confidence interval) for field‐scale 68.3 ±8.7 the...
