Innovative Drainage Alternatives: Infiltration Solutions and Case Study Analysis

This presentation delves into alternative drainage techniques, focusing on the La Riereta Basin case study in Saint Boi Llobregat. The project highlights innovative solutions to reduce soil impermeability from 100% to 60%. By employing infiltration basins and shallow trenches, we achieved an impressive flood volume reduction of 88%, from 1.896 million to 0.230 million liters. This study emphasizes effective rain modeling, the importance of managing impermeable areas, and showcases how combined solutions can significantly mitigate flood risks.

  1. Alternative Drainage Techniques : Infiltration Team 3 Ariel Marcelo Ravelli (Argentina) Lina Mabel (Chile) Vinícius de Mello Moutinho (Brasil)

  2. Theme Presentation • Case of Study • Rain and Modeling • Adopted Solution • Results

  3. Theme Presentation • Drainage Alternative Forms • Trenches • Storage Rooftops • Permeable Pavement • Infiltration Basins

  4. Case of Study La Riereta basin, Saint Boi Llobregat Basin 100% impermeable 1% to 7% average slopes Area of 18 ha Unitary Drainage System

  5. [1] These subcatchments had it´s width calculated as symmetrical, W= 2*L, while the others were calculated as asymmetrical, W=(2 - Sk) x L, Sk= (A2 – A1)/ A Subcatchments Features

  6. Rain and Modeling

  7. Rain and Modeling 3 Rains: Jordi, Fidel and Martina

  8. Rain and Modeling Calibration : Fidel First Round Last Round

  9. Rain and Modeling Validation : Jordi Error: peak: 0.4% volume: 34%

  10. Project Rain

  11. Project Rain Full Rain Reduced Rain

  12. Local Problem

  13. Solutions • Reduce Impermeable Area • Combined Solution

  14. Solutions • Reduce Impermeable Area from 100% to 0%

  15. Solutions • Combined Solution • Imper. Area – 60% • CN – 60 • Infiltration Basin • Shallow Trenches

  16. Solutions

  17. Solutions Total Volume Reduction : 88%

  18. Conclusions 100% to 0% we still had a flood, an amount of 0.46% of the inicial flood. Combined solution, we were able to reduce the soil impermeability from 100% to 60%, and using the infiltration basin and the trenches, we reduced the total flood from 1.896 x 106 to only 0.230 x 106 ltrs, a total reduce of 88%

  19. Problems Good Management Required
