The Calibration of 2-D Shallow Water Flow Models

Abstract

In Hydraulic Engineering, numerical simulation models are frequently used to analyse (tidal) water movements. To standardize and simplify the generation of these models program packages are developed. One of these packages is based on a one dimensional, the other on a two dimensional description of the dynamics. A serious problem in relating the model outcome to observations of the process is the uncertainty of some model parameters that is introduced by empirical relations. To calibrate the models two different approaches are commented in order to find the appropriate values for these parameters, while other uncertainties (for example with respect to boundary conditions) are also taken into account.
