I am interested in many surface processes and patterns, including rivers and a range of desert, arctic, and alpine phenomena. My recent efforts have focused on coastal and nearshore processes. The nearshore environment is a spatially extended system that exhibits complex, dynamic spatial patterns, including the arrangement of bars and channels, waves, and often an array of alongshore and cross-shore currents. I approach such systems with the perspective and techniques developed in the study of nonlinear dynamics and complex systems, looking for possibly simple, large-scale interactions that could explain complex behaviors. I use relatively simple, cellular-automata-like models to test such hypotheses. (click here for recent abstracts) Recently I have been applying these methods to beach and surf-zone problems, but I am expanding my focus onshore and offshore, to include studies of storm-driven currents and sediment transport kilometers from shore, as well as the formation and evolution of shoreline-scale features such as cuspate forelands and capes, cuspate spits, and 'sand waves'. Another aspect of my research involves comparing field or laboratory observations with models of complex systems, for which linear statistics concerning the system's behavior may not sensitively reflect the interactions that produced them. I apply and develop nonlinear data analysis techniques to sensitively test how realistic model interactions are. I also advocate using different model-testing strategies for maximally-realistic simulations and highly simplified models. (See model testing for more information.)
