An initial attempt at using the lattice Boltzmann method (LBM) to study afflux has been made in this paper. The LBM representing the 2D nonlinear shallow water equations (LABSWE) is applied to both single-span and multi-span bridges with a free water . Drainage Manual (RDM)) with ARR19 IFD and/or other techniques such as QRT should be peak water levels of all critical durations (in either Base Case or (peak of peaks) for that specific AEP event. Afflux for each AEP event is determined by the difference in composite peak water levels between the Design Case and the Base Case.

“afflux refers to the predicted change, usually in flood levels, between two scenarios. It is frequently used as a measure of the change in flood levels between an existing scenario and a proposed scenario.” TUFLOW Manual, Afflux in motion developed in OpenFOAM a free CFD Modelling program, shown below. in the current CIRIA culvert design manual. The Afflux Advisor models flows ranging continuously from free surface subcritical flow below the soffit of the bridge or culvert to totally drowned flow. Uncertainty is quantified as a function of method choice and roughness values. The Afflux Advisor manual.
