- COMPROMISE SOLUTION BETWEEN CELL SIZE AND TOPOGRAPHY

CHARACTERISTICS

- WATER LEVELS ADJUSTED TO THE TOUS OUTFLOW HIDROGRAPH OVER

THE VALLEY

- THE MOST “ECONOMICAL” CITY MODEL: VERTICAL WALLS

● MESHING DIFFICULTIES

● LONG DURATION OF SIMULATIONS

- PROBLEMS WITH THE SELECTION OF DOWNSTREAM BOUNDARY

CONDITION

- MODELS SEEM TO REPRODUCE URBAN FLOODING SLOWER THAN IT WAS

(FILLING UP AND CITY EMPTYING).

- UNCERTAINTY IN THE RESULTS UP TO 5m IN THE VALLEY AND AROUND 2m

IN THE URBAN AREA BETWEEN BATHYMETRIES AND MODELLERS
