"r.water.fea" is a finite element analysis program for hydrologic
simulations, developed
by Dr. Baxter Vieux and Nalneesh Gaur at the University of  Oklahoma.  You
may extract
the code and readme files  (r.water.tar.Z and r.water.README) from the moon
anonymous
ftp site (129.229.20.254).  Associated reference: Vieux, B.E., Bralts,

A finite difference hydrologic analysis program ("r.flow" ??) is being
developed by
Dr. Bahram Saghafian at USACERL, Champaign, Illinois. I believe he is
currently on leave,
 but plans to return to CERL. Reference: Doe, William  W., and Bahram
Saghafian, (1993),

(the model integrated is the CASC2D model).
