| 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 |
| 25 | | |

| 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? |
