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 Users Manual:
For video demonstrations of the FLUVIAL-12 model, select of the following:
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.
The following are sample input data files that can be used with the demo program:
sample1.dat Santa Cruz River with curved channel, soil cement bank protection, and grade control structure, Tucson, Arizona
sample2.dat Escondido Creek with proposed bridge, Encinitas, California
sample3.dat Little Kansas River, Kansas
sample4.dat San Dieguito River, San Diego, California
sample5.dat Upper San Diego River scour prediction at road crossing, San Diego, California
sample6.dat Otay River scour prediction at pipeline crossing, Chula Vista, California
sample7.dat Santa Cruz River showing lateral channel migration, Tucson, Arizona
sample8.dat Fall River, Colorado
sample9.dat Santa Cruz River showing lateral channel migration, Tucson, Arizona
