DYNLET1 Application to Federal Highway Administration Projects
Abstract
This study was sponsored by the U.S. Department of Transportation (DOT) whose primary interest is in the development of a statistical approach for estimating frequency-indexed currents impacting bridge piers at project sites. Model DYNLET1 is used to compute the storm-induced velocities near bridge piers. DYNLET1 is a one-dimensional (1-D), shallow-water equation, hydrodynamic model for predicting velocities and water level fluctuations in a system of inlets and bays (Amein and Kraus 1991, 1992). An important feature of the model is the ability to accurately represent flow distribution across any cross section, given the inherent limitations of a 1 -D model. This report describes the process of applying DYNLET1 to a tidal inlet, specifically to Brunswick Harbor, Georgia, for the purpose of estimating tide and storm response at U.S. Department of Transportation (DOT) project sites.
