… This thesis proposes a two-dimensional finite element method that overcomes many of
the numerical difficulties encountered when solving the two-dimensional shallow water flow
equations. The finite element method facilitates the use of an unstructured grid and thus is
able to accommodate complex domain geometry. A routine has been developed … As one
important application of the two-dimensional model is in the field of simulation of flow in
aquatic habitats, Appendix B reviews and discusses the different Instream Flow Needs (IFN) …
