The CARIMA code simulates unsteady free-surface flow in simple or multiply connected systems of rivers or canals. The simulation uses the Preissmann implicit finite-difference method for solution of the complete de St. Venant equations and appropriate equations for hydraulic structures. Special features of the code include automatic topology recognition, a user interface for fully implicit incorporation of specialized supervisory and global control schemes, and the lack of any pre-set limits on network complexity or size of data tables.
