2. Methodology Delimitation and discretization of study area. Determination of hydraulic parameters. Determination of effective rainfall. Obtaining the storm design. Modelation with the SWMM program. Modification to the drainage system. 2

3. Study Area- “La Riereta” Basin Total area: 17.99 Hectares High percentage of impervious areas Combined sewer system Circular Sections Concrete 3

4. Discretization of basin Total Sub basins: 18 Basin Roughness: 0.0015 Conduit Roughness: 0.01 4

5. Calibration Fidel event Determination of effective rainfall P T =P E +P P For the cablibration the N impervious was changed to 0.0015 and also the time steps. 5 FIDEL Flow Qptp [m 3 /s][hour] Measured0.2101:13 Calculate d0.3102:25 E r [%]4699

11. Solution Proposal Tiempo de inundación N-31 15 min Tiempo de inundación N-33 55 min Tiempo de inundación N-31 1 min Tiempo de inundación N-33 1 min 11 Area 1

12. Solution Proposal Flooding time:12 min Flooding time:1 min 12 Area 2

13. Solution Proposal Tiempo de inundación 5 min Tiempo de inundación 2 min 13 Area 3

14. Conclusion Flooding succesfully controlled with the proposed alternatives. New drainage system larger and more expensive than the current system. Spots with flooding ocurring for a minimum time Integration of various techniques in order to minimize costs and impacts of drainage works in urban areas 14
