Delta morphology is impacted by upstream and downstream boundary conditions that operate over a range of spatial and temporal scales. Here, we explore the effect of a particular boundary condition, episodic tectonic subsidence, on delta dynamics using field data collected from the Selenga River Delta, Russia, and analytical models.

Partitioning of water and sediment discharge at a river bifurcation is a complex process. The distributary network of a river delta often contains numerous bifurcations; therefore, predicting flux distribution is very difficult. Here, we develop a graph model to predict flow partitioning in a delta network solely based on remote sensing data. This framework is applied to multiple deltas worldwide, and predictions agree with field data.
