FLUVEX (FLUVial EXpert) combines methods for the calculation of uniform and non-uniform flows in rivers. The simple use of the different modules allows to treat and solve many practical problems in a fast and efficient way. The program helps to exploit the full information of given cross-section data. Additional modules for the transport of sediments and dispersion extend the applications to problems of river maintenance and river ecology.

The numerical model has the following distinctions:
stability for critical and supercritical flow regimes (steady)
stability for subcritical flow regimes (unsteady)
thermal mixing with stream-tube approach
modular design


Velocity distribution in river Rhine at Basel

Uniform Flow
flow capacity in simple and compound channels with variable bed roughness
distribution of flow velocity and bed shear in cross-sections
including friction losses due to vegetation
transport capacity for sediments
 
 

Temperature distribution for thermal inlet

Non-Uniform Flow
backwater calculation for sub- and supercritical flow regimes
weirs, gates and culverts
inflows and outlets
side-weirs and side-gates
distribution of flow velocity and bed shear
transport capacity for sediments
travel times
two-dimensional dispersion (stream tube approach)
unsteady flood routing with four-point scheme (Preissmann scheme) 
bed evolution (mobile bed) with VAW formula
