Water Level and Current Prediction for the JLOTS III Exercise, Coast of North Carolina
Abstract
New technology for detailed numerical modeling of water levels and currents at potential Logistics Over the Shore (LOTS) sites is developed and demonstrated in preliminary form in conjunction with the JLOTS III exercise. The new technology offers great potential for systematically developing large-scale regional models which are driven by operational global scale tide and wind models. Nearshore areas of special interest, even complicated areas with shoals, islands, and channels, can be represented with exceptional detail and accuracy. The numerical model is applied to four sites along the North Carolina coast to develop water level and current information for LOTS site selection and operational forecasting. The initial and key modeling steps are performed with the long wave hydrodynamic model ADCIRC. The model is applied in the following two ways: (1) force with astronomical tides to create tidal constituent amplitudes and phases for elevations and currents at LOTS sites; (2) force with local wind fields to create table relating local wind to local water level and current. Follow-on programs were written as part of this study to combine the above tide and wind effects on water level and current and produce information in a form for the following: (a) Selecting optimum sites for LOTS operations; (b) Forecasting throughput during a LOTS operation. The user-oriented forecasting program and its results were demonstrated onsite during the JLOTS III exercise. These products will be more formally integrated into the comprehensive LOTSSITE and LOTSTP software packages under development at WES.
