6 | | * Supercritical flow (e.g. over weirs) as well as sub critical flows handled seamlessly |
7 | | |
8 | | * Bores handles well due to discontinuities allowed in solution |
9 | | |
10 | | * Numerically stable |

14 | | === Identified weaknesses === |
15 | | |
16 | | * ANUGA is not as fast as some other models |
17 | | |
18 | | * More diagnostics needed, e.g. time series, vector plots, extrema (dynamically store max stage/velocity: ticket:192) |
19 | | |
20 | | * Easy way of extracting time series - GA to provide example to Tom of extracting depth/veloctiy at a time step |
21 | | |
22 | | * Information on how sww file has been built not documented well enough |
23 | | |
24 | | * Wave attenuation over long distances and coarse grids identified by Will Power |

28 | | === Emerging opportunities for future work === |
29 | | |
30 | | * Time varying bathymetry ticket:191 |
31 | | |
32 | | * Validation for wave setup on planar beach (UQ interested in looking at this) |
33 | | |
34 | | * Culverts: ticket:145 |
35 | | |
36 | | * changing the mesh resolution - specify period of wave etc to work out maximum triangle size (adaptive mesh generation, ocean model from Imperial College) - inter-run adaptive mesh resolution - a better mesh tool - could we view the where the small triangles are? Interact with a GIS tool? By Xmas, Ted will have a nice GUI front end for flood modelling. |
37 | | |
38 | | * dynamic roughness - Manning's function - is the coefficient a function of depth? |
39 | | |
40 | | * fluid density - picking up debris (mud flow) |
41 | | |
42 | | * frequency dispersion |
43 | | |
44 | | * kinematic viscosity |
45 | | |
46 | | * optimisation; often only a few triangles causing small time steps - can they be dealt with heuristically? |
47 | | |
48 | | * subversion - third party contributions, isolate core of ANUGA. |
49 | | |
50 | | * applying a hydrograph at an upstream point |
51 | | |
52 | | * landslide over time rather than instantaneous (implement as forcing term) |
53 | | |
54 | | * randomly generated bathymetry - does is cause instability? |
