Abstract

This study aims to identify the best combination of Sustainable Urban Drainage System (SuDS) types for an Indian City, Bengaluru by integrating InfoWorks ICM (Integrated Catchment Modelling) and Multi Criteria Decision Making (MCDM). SuDS which have been proven efficient in reducing flood impacts, is modelled for the stormwater drainage system of Bengaluru to assess its effect for the selected study area in the city. A small area of 0.86 sq.km which lies in between the West core Zone and RR Nagara Zone is selected as the study area. The drainage design is modelled in InfoWorks ICM software and the AHP (Analytical Hierarchical Process) and TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) is used to find the best LID (Low Impact Development)/SuDS (Sustainable urban Drainage Systems) combination for the study area.

The findings suggest that implementing SuDS for Indian Cities can reduce the effect of flooding by managing Peak Flow and Runoff by the various SuDS/LID types. We have used the Green Roofs, Permeable Pavements, Bio Retention Cells and Rain Barrels, which were applied as four different combinations to reduce the quantity of flood occurring in the study area for design period rainfall of 5 yr, 10 yr and 15 yr return period. For the return period of years, the combination of Rain Barrels, Permeable Pavements and Bio Retention Cells were identified as the best LID combination, for the return period of 10 years, the combination of Rain Barrels and Green Roofs were identified as the best LID combination. In the case of 15 yr rainfall, again the combination of Rain Barrels and Green Roof were identified as the best LID combination. The results shed light on the opportunities and limitations for Indian Cities for applying SuDS.
