摘要

This report describes the theory, methodology, and verification of the ADCIRC (ADvanced CIRCulation) finite element numerical models. ADCIRC-2DDI is a two-dimensional, depth-integrated hydrodynamic model. ADCIRC-3DL is a three-dimensional model that couples the external mode solution generated by ADCIRC2DDI to a locally one-dimensional internal mode solution. The numerical internal mode solution can be obtained using either velocity or stress as the dependent variable. ADCIRC has been developed to simulate hydrodynamic circulation along shelves, coasts, and within estuaries. To allow long numerical simulations (on the order of a year) over very large computational domains (for example, the entire east coast of the United States), ADCIRC has been designed to have high computational efficiency and has been tested extensively for both hydrodynamic accuracy and numerical stability. The results of these tests are included in this report....
