Abstract:

This award supported research on modeling nearshore processes as complex systems. This research was motivated by the observations that the processes operating in the nearshore are dominantly nonlinear and dissipative and that the nearshore often exhibits behavior that is not linearly connected to forcing by incident waves. The hypothesis that the nearshore is a complex system was explored by 1 research on the general properties of complex systems and their relationship to natural systems, 2 modeling bedforms 3 continued analysis of measurements from experiments testing a self-organization and standing edge wave models for beach cusp formation, and 4 initial and ongoing development of complex systems models for infragravity wave generation in the surf zone and coupled sand bar and shoreline evolution.
