Multiple Equilibrium Configurations in River-Dominated Deltas

Lorenzo Durante, Nicoletta Tambroni, and Michele Bolla Pittaluga

Abstract. The morphological evolution of river deltas is a complex process influenced by both natural forces and human interventions. As hubs of human settlement and economic activity, deltas face unique challenges that necessitate integrated management strategies to balance development with ecological sustainability. This study investigates multiple equilibrium states within deltaic systems, revealing key internal feedback mechanisms between delta branches through a novel theoretical model tailored to river-dominated delta channels. Focusing on the Po River Delta as a case study, we analyze equilibrium variability and identify potential avulsion sites. These findings provide a valuable framework for predicting future shifts in deltaic morphology and supporting adaptive management strategies.

Short summary
River deltas are dynamic areas where rivers meet the sea. This study examines delta configurations to guide balanced development and environmental health. Using the Po River Delta, we developed a model to understand how different delta parts interact and maintain balance. Our findings show that deltas can reach varied states of balance, with some areas more prone to shift. These insights support predictions of delta changes and better management strategies.
