Flow Adaptive Schemes

A study in the development of flow adaptive numerical schemes in computational hydraulics directed to enhancing modelling capabilities. Four examples are covered: additional flow resistance due to flexible vegetation; one-dimensional supercritical flow; flow in networks of channels; and nearly horizontal two-dimensional flow. All of the schemes developed show similar features, employing intermediate results of computation in order to achieve a better. By adopting the point of view of cybernetics, these numerical schemes are examined as control systems. For the purpose of characterizing flow adaptive schemes, a process of deconstruction was followed, starting with the most simple example of an implicit numerical scheme.
