Considerations for Modeling Vessel- Generated Currents and Bed Shear Stresses

Abstract

This Coastal and Hydraulics Engineering Technical Note (CHETN) contains a description of the new vessel effects capabilities in the hydrodynamic code ADaptive Hydrology/Hydraulics (ADH). Guidelines for creating initial mesh refinement along a sailing line are included as well as determining the values for parameters that control automatic mesh adaption during a simulation. ADH has also been extended to include calculations of bed shear stresses induced by flat-bottomed vessels. These shear stresses can be used in modeling sediment resuspension.
