AB  - In order to enable estimation of flood damage due to sewer 
  overflow, a Sewer Network Model (SWMM) was coupled with an Inundation Model 
  (BreZo) based on irregular triangular meshes. SWMM uses a 1D explicit finite 
  difference solver that handles the full shallow water equations. BreZo employs 
  a Godunov-type finite volume algorithm to explicitly solve the shallow water 
  equations. The model coupling was effected by transferring mass (and neglecting 
  momentum) from the Sewer Network Model to the Inundation Model. The flow back 
  into the sewer network during the recession hydrograph from the surface was 
  not considered. The model was evaluated by applying it to a case study taken 
  from the urban drainage system in West Garforth, UK. The model application showed 
  that computational economy was achieved. Also, the coupled model performed well 
  against stability and mass balance criteria.
