Dr. Alejandro Tejedor: Understanding deltas through the lens of their channel networks

Project summary

Delta channel networks exhibit complex patterns that are key for understanding delta self-maintenance and resilience to external perturbations. The proposed research aims to study deltas through the lens of their delta channel networks via a three-pronged approach based on graph-theory, numerical modeling, and the analysis of more than 60 field deltas of diverse hydroclimatic environments and levels of anthropogenic influence. The ultimate goal is to advance our understanding of delta morphodynamics and response to change by: (1) relating network properties to the underlying physical processes, (2) proposing a delta classification framework, and (3) exploring delta self-organization in terms of optimality principles and interpreting possible deviations.
