FMA Challenge 2: Difference between revisions

This section provides an overview and discussion of the model domain setup.<br> All files required to re-run the model can be found at '''FMA_Challenge_Models/FMA_Scenario2/'''. It is at your discretion which GIS package, text editor and method of model simulation to use (batch mode or within the text editor).

 

A series of fixed, north-south oriented grid domains were developed. The coarsest fixed grid resolutions were sufficiently detailed to represent the river bathymetry, so no 1D/2D coupling was incorporated. A fully 2D solution is preferable over a 1D/2D linked representation provided the 2D resolution of the primary flowpaths is sufficiently fine. A minimum recommended 2D resolution across the river for TUFLOW for this model is a 30m grid (it is recommended that a minimum of 4 fixed grid cells be used for modelling a primary flowpath). For this model the upper sections near the two inflows are not represented well, especially the northern Tributary Inflow. However, this is unlikely to have an adverse effect on the objectives of the modelling, but would affect the comparison to the high water marks near these inflows.
