Fort.15: Model Parameter and Periodic Boundary Condition File
=============================================================

The fort.15 file contains the majority of the parameters required to run both the 2DDI and 3D versions of ADCIRC and the information to drive the model with harmonic boundary conditions (either elevation or flux). This file is required to run the ADCIRC model.

File Structure
--------------

The basic file structure is shown below. Each line of input data is represented by a line containing the input variable name(s). Loops indicate multiple lines of input. Conditional input is indicated by a clause following the variable name(s).
