"r.water.fea" is a finite element analysis program for hydrologic
simulation. It was
developed by Dr. Baxter Vieux and Nalneesh Gaur at the University of Oklahoma.
The code and readme files (r.water.tar.Z and r.water.READEM) may be obtained
 from the moon anonymous ftp site ( Associated reference:

Watershed Modeling: One-Dimensional Elements", J. of Water  Resources
Planning and Management,  Vol. 116, No. 6, p. 803-819.

A finite difference hydrologic simulation program  (r.flow ??) is being
by Dr. Bahram Saghafian at USACERL, Champaign, Illinois. I believe he is
currently on leave, but that he plans to return to CERL. Reference: Doe, W.

(CASC2D is the model integrated.)
