Abstract: A system of 3 tidal intrusion fronts persists in a small area off Newport News Point during the early phase of flood tide in the lower James River Estuary, one of the tributaries of the Chesapeake Bay. The two smaller fronts result from the existing flows over the flats that plunge into the deep channel at the western end of Newport News Point and the deep basin to the southwest, respectively. The third front results from the advancing flood current along Newport News Channel. The horizontal scale for the frontal development is about 3 km. To simulate the frontal system, a numerical model using a fine-resolution grid is required. In this study, we used the Unstructured Tidal, Residual Intertidal, and Mudflat (UnTRIM) model to simulate the frontal system. A high-resolution unstructured grid was used over the region of the frontal system and coarser grid cells were used in other areas. Model results show that this unstructured grid model can simulate the stratificationdestratification processes in the estuary, which play an important role in the variation of the strength of the frontal system. The model successfully simulates the circulation pattern of the estuary and the evolution of frontal system. The results demonstrate that the unstructured grid model is capable of simulating such small-scale estuary frontal systems.
Description: Paper presented at The Seventh International Conference on HydroScience and Engineering (ICHE) hosted by the College of Engineering at Drexel Univeristy on September 10-13, 2006 in Philadelphia, Pennsylvania. The conference theme was IT in the Field of HydroSciences. It included several mini-symposia that emphasized IT topics in HydroSciences and the yearly meeting of the metadata group of the International Oceanographic Data and Information Exchange organization.
