Overview

Bed erosion and deposition areas on the Hoh River for a 100-yr event hydrograph.

RiverFLO-2D is a hydrodynamic, and mobile bed model for rivers. It is a finite element model to route floods and provides high resolution flood hydraulics. Flexible triangular mesh refines the flow field around key river features in complex river environments. RiverFLO-2D has been applied on a number of river projects worldwide including large rivers in South America and in the United States. RiverFLO-2D is a perfect companion to the FLO-2D model which interfaces a depth-integrated, 1-D channel routing model with the 2-D unconfined floodplain routing. FLO-2D can route a large flood to the project river reach, accounting for floodwave attenuation and detailed floodplain features. RiverFLO-2D can then predict the detailed 2-D channel hydraulics and overbank flooding through the shorter project reach. RiverFLO-2D user interface is based upon Argus Open Numerical Environment (Argus ONE). This GIS-integrated software system provides interactive functions to generate and refine the finite element mesh. It also facilitates, assigning boundary conditions and roughness values. By importing and exporting multiple GIS layers, the user can graphically display the model results in a number of formats. RiverFLO-2D computation engine uses an efficient and stable finite element solution method that solves most of the boundary and hot start difficulties of similar 2-D channel models that are now outdated. RiverFLO-2D is a state-of-the-art, high performance model designed for multiple processor computer systems.

TWO-DIMENSIONAL FINITE-ELEMENT RIVER DYNAMICS MODEL

A.S.A.P. Modeling with RiverFLO-2D

Advanced
RiverFLO-2D uses a state-of-the art finite element solution algorithm that solves most of the shortcomings of comparable models. The explicit time-stepping algorithm does not require solution of large matrix systems and provides flexibility for efficient parallelization.

Stable
RiverFLO-2D provides one of the fastest and more stable 2D finite element models commercially available for supercritical and subcritical flows. The computer code has been parallelized using OpenMP standard instructions providing considerable computer-time savings and taking advantage of multi-core computers (Duo/Quad) that use MS-Windows XP or Vista operating systems.

Accurate
RiverFLO-2D provides a mass conservative and robust dry-wet treatment method that allows to dry large mesh areas without generating artificial velocities or surging. The model reports on volume conservation allowing users to assess the model accuracy as the simulation progresses.

Productive
RiverFLO-2D minimizes time consuming model setup time letting you run more scenarios and concentrate in the actual model application and results analyses. RiverFLO-2D helps you be more productive allowing starting the simulation with the real initial conditions even if the whole river bed is dry.

Model Applications
RiverFLO-2D can be applied to time-dependent and steady-state two-dimensional river simulations for either rigid bed or mobile bed applications. The model generates high resolution spatially variable results with a detailed depiction of the flow field. Typical model applications include:
• Detailed in-channel river hydrodynamics;
• River overbank flooding;
• Levee removal;
• Dam-break flood analysis;
• Sediment transport – mobile bed;
• Bank erosion protection design and analysis;
• River restoration design.
