dc.descriptionTechnical note-
dc.descriptionPurpose: In this investigation the ADaptive Hydrology (ADH) code is being used to produce the effect of a vessel in a waterway by moving a pressure field that displaces the vessel "footprint" along the navigation channel. As the vessel moves, it creates a drawdown and return current pattern. The adaption is being relied upon to capture the hydrodynamics and also to precisely match the forcing supplied by the vessel pressure field. ADH allows the user to set up a mesh that only needs to capture the geometry of the domain, and the model will then automatically refine the mesh to accurately represent the flow field. ADH is a code that can be used for a variety of hydrodynamic problems, including groundwater and flow in and around hydraulic structures. In this case, ADH is being used in the two-dimensional (2-D) shallow-water mode. For more information on ADH see Berger and Stockstill (1999) or Stockstill and Berger (2001). The Shallow-water Refinement Tolerance (SRT) value used in ADH triggers the adaptive refinement. This CHETN allows users to estimate the appropriate value of SRT so that they may conduct accurate investigations of vessel effects in deep-draft waterways. This technical note is intended for investigators with some experience with the shallow-water mode of ADH.-
