The FLUVIAL-12 mathematical model is an erodible-boundary model that simulates interrelated changes in channel bed profile, channel width and bed topography.  The model requires an input hydrograph(s), channel bed material composition, and channel cross-sectional data similar to that used in HEC-2.  


For a detailed description of the FLUVIAL-12 model, download the User’s Manual:


FLUVIAL-12 User's Manual



For video demonstrations of the FLUVIAL-12 model, select of the following:


          Miller Creek


          San Dieguito River



For a demonstration version of the model, download the instructional program.  The instructional program only allows up to eleven channel cross-sections to be modeled.  This is sufficient to illustrate the capabilities of the model.  However, it is not sufficient for performing engineering design.
