Abstract

Monte Carlo simulations of a two-dimensional depth-averaged distributed bed-roughness flow model, TELEMAC-2D, are used to model a detailed tracer dispersion test in a complex reach of the River Severn in the Generalized Likelihood Uncertainty Estimation (GLUE) framework. A time efficient, zero equation, spatially distributed eddy viscosity model is derived from physical reasoning and used to close the flow equations. Finally, a new technique for visualizing the distributed prediction limits in the GLUE procedure by generating hypothetical weighted tracer concentration fields is demonstrated
