Abstract:

The Computational Hydraulics Committee has established a Task Committee to identify test cases which can form a uniform, objective basis for model verification. The scope is limited to two-dimensional (2-D), depth-averaged hydrodynamic models. Specific objectives include: to select analytic solutions with realistic parameters and which address specific features; to facilitate the utilization of these by publication of either algorithms for evaluating the solutions, or specific analytic results in printed or graphical form; to improve the availability of field data sets; to establish measures of effectiveness - mass balance, momentum balance, stability, etc; and to propose a series of 'challenge' cases from above, which could form a continuing series of conference sessions. This paper reports on the progress of the committee.
