ADCIRC: An Advanced Three-Dimensional Circulation Model for Shelves, Coasts, and Estuaries. Report 2. User's Manual for ADCIRC-2DDI
Abstract
This report describes the use of model ADCIRC-2DDI, a two- dimensional, depth-integrated, finite-element-based hydrodynamic circulation code. ADCIRC-2DDI solves the shallow-water equations in their full nonlinear form and can be forced with elevation boundary conditions, zero normal boundary fluxes, variable spatial and temporal free surface stress and atmospheric pressure forcing functions in addition to Coriolis and tidal potential forcing terms. The algorithms that comprise ADCIRC-2DDI allow for extremely flexible spatial discretizations, which results in a highly effective minimization of the discrete size of any problem. Furthermore, these algorithms show good stability characteristics, generate no spurious artificial modes, have no inherent artificial damping, and are extremely efficient. The resulting model can be applied to computational domains ranging from the deep ocean to estuaries. Furthermore, the model is able to efficiently run months to years of simulation while providing detailed intra-tidal response characteristics. A compete description of all user aspects is given in this document, including code setup and a description of all input and output files. Both model-specific and general modeling practices are discussed. Finally, two examples are presented. Sample input and output files for these examples are included in Appendices A and B.
