Background and Applications of Fluvial-12

Document Type: Proceeding Paper

Part of: Sediment Transport Modeling


The computer program FLUVIAL-12 is formulated and developed for water and sediment routing in alluvial channels. The combined effects of flow hydraulics, sediment transport and river channel changes are simulated for a given flow period. River channels changes simulated by the model include channel bed scour and fill, width variation, and changes in bed topography induced by the curvature effect. These inter-related changes are coupled in the model for each time step. While this model is for erodible channels, physical constraints, such as bank protection, grade-control structures and bedrock outcroppings, may also be specified. This model may be also used on a PC, such as an IBM-PC-AT or -XT or a compatible. Model applications are discussed.
