| Abstract |
The VH-LU model is based on a finite-volume approach for solving the time-domain nonlinear shallow water equations (NSWE) and Boussinesq equations on either structured or fully unstructured grids. Both moving and stationary vessels are incorporated into the simulations using hull forms input as finite-difference grids, allowing any vessel or object shape to be incorporated into the simulation. The vessels are either stationary or move through the domain by user-prescribed temporally and spatially variable routes, speeds and accelerations. Developed as part of a coastal engineering hydrodynamic system, the VH-LU model also includes structured or fully unstructured simulation of ambient flows, water level fluctuations, ambient waves, sediment transport, bottom morphology, and water quality using a suite of stateof- the-art algorithms. Previous publications have described the VH-LU system validation of water level and velocity fluctuations generated by pressure fields with field measurements as well as berthed vessel loading verification exercises performed using physical model data. The present paper provides a summary of these validations and modeling system improvements for predicting sinkage of passing vessels (validated using empirical formulations), validation of hydrodynamic effects on shallow banks and preliminary non-dimensional predictions of maneuvering force effects from laboratory studies. |
