This Coastal Engineering Technical Note provides guidance on specification of tidal boundary conditions for the ADvanced CIRCulation Multi-dimensional Hydrodynamic Model ADCIRC circulation model within the Surface-Water Modeling System SMS. This technical note is one in a series prepared by the Coastal Inlets Research Program documenting specific features of the SMS developed for ADCIRC applications. Circulation modeling of open ocean regions applies tidal forcing as an ocean boundary condition. Tidal forcing consists of one or more tidal constituents, such as the M2 constituent, applied at each boundary point. At tidal boundaries, time- and space-dependent information is specified that is unique for each tidal constituent. A tidal constituent toolbox was developed within the ADCIRC module of the SMS to provide a convenient user interface for specifying tidal forcing for ADCIRC circulation modeling. This technical note describes tidal constituents and the toolbox, including instruction for tidal boundary condition specification. The tidal constituents toolbox was implemented in Version 6 of the SMS.
