    4 === Identified strengts ===
     4ANUGA meeting 30th August [Minutes]
    55
    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
    11 
    12 
    13 
    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 
    26 
    27 
    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?
