Influence of land use changes on Urban flooding - Case study of Bangalore city, India

Shubha Avinash, K. Lakshmi Prasad, G.S. Srinivasa Reddy, D. Mukund


In past few years, Bangalore city is facing the flood disasters frequently during monsoon seasons. The land use change study is carried out for the most flood prone watersheds in the city for the years 1995, 2000, 2005, 2010, 2015 and 2018. Google earth image is used to investigate the land use changes using Google pro tool. The study has showed an increasing imperviousness in the study area of Koramangal-Chellaghatta Valley (KC Valley) watershed region. The average runoff coefficient corresponding to the land use changes has increased from 45% in the year 1995 to 91% in the year 2018. The case study of 2016 flood event in the city shows, location specific hydrological behavioural changes in few of the frequently flood vulnerable areas in KC valley. The study also shows details on missing water bodies and missing stream links which is also one of the major reasons for the flood events in the study area.  Overall, it is evident that, land use changes in form of increased imperviousness, missing water bodies, missing stream slinks due to urbanising factor has increased the flooding frequency in Bangalore city.
