ONR Tidal Flats DRI: Planning Joint Modeling and Field Exercises

Abstract : The ultimate goal of this work is to assist in the development of science plan for gaining a state-of-the-art understanding of macro-tidal, muddy estuarine/coastal environments through field experiments and modeling efforts. This is a challenging environment for a modeling framework, due to complexity of both the tidal currents and sediment erosion and deposition patterns. The morphologic modeling perspective has been our focus. The objective of the first phase of this work is the planning and development of joint modeling and field exercises, through attendance at and participation in the workshops hosted by the Office of Naval Research. Later phases will result in the potential development of a model of selected site(s), with validation and calibration facilitated by field program based on both in-situ and remotely sensed measurements. Battelle's specific participation was geared toward the circulation, transport and geomorphological modeling of these environments and incorporation of this perspective into the overall science plan. The use of models to help address the relative importance of tidal and river discharge to geomorphology has been identified as a key issue.
