Abstract: The Staggered Net Unsteady State Model (SNUSM) was developed in the early 1980's by the United States Bureau of Reclamation under the direction of Bob Gooch and Al Graves. The primary purpose for developing this model was to obtain very accurate flow and depth projections in the Central Arizona Project (CAP) canal system to be used in the development of methods to regulate flows for both normal operations, and in reaction to emergency conditions [Gooch & Graves, 1985] [Gooch, 1983a]. Although originally developed to be used for the CAP, it has also been used on other canal systems including the Tehema-Colusa canal in California, Ministry of Irrigation in Egypt, and the Canal de Cartagena in Spain with good results. The field application of SNUSM has resulted in a greater degree of refinement and robustness than most generic canal unsteady state models.
