Runoff Simulation in Large Rural and Urban Areas Using Mike 21 Flexible Mesh Modeling

The paper presents the way of construction and modeling of the runoff on rural and urban areas.Mike 21 Flexible Mesh software generates results in bidimensional hydrodinamic files that highlight the flow, speed, water level and space expansions of the flooded areas. The bidimensional model is calibrated with reference terms of the measured water level in the modeled area, the maximum limit of the hystorical flood recorded by physical landmarks. It also uses roughness parameters for land use on the analyzed extents
