NAME
       feswms-2dh - Finite-element surface-water modeling system for two-
                    dimensional flow in the horizontal plane

ABSTRACT
       FESWMS-2DH is a modular set of computer programs that simulates two-
       dimensional, depth-integrated, surface-water flows. FESWMS-2DH
       consists of an input data preparation program (DINMOD(1)), flow
       model (FLOMOD(1)), simulation output analysis program (ANOMOD(1)),
       and graphics conversion program (HPPLOT(1)). The programs have been
       developed to analyze flow at bridge crossings where complicated
       hydraulic conditions exist, although they may be applied to many
       types of steady or unsteady flow problems.  Shallow rivers, flood
       plains, estuaries, and coastal seas are examples of surface-water
       bodies in which flows may be essentially two-dimensional in the
       horizontal plane.

SYSTEM REQUIREMENTS
       FESWMS-2DH is written in Fortran 77 with the following extensions:
       use of variable names longer than 6 characters, mixed character and
       non-character variables in common blocks, use of explicit length
       declarations (INTEGER*2, INTEGER*4, REAL*4), include files, and
       reference to compiler-dependent system date and time routines.
       Graphics are coded using Computer Associates' DISSPLA library
       references.  Generally, the program is easily installed on most
       computer systems that have access to the DISSPLA graphics library or
       if the graphics are disabled by the user modifying the code.  The
       code has been used on UNIX-based computers.
