Drainage congestion and increased rainfall runoff over eight centuries are increasingly choking Dhaka, the "unplanned Capital of Bangladesh", and this is leading to internal flooding, reports Panos Features, citing a recent study by S Dara Shamsuddin and Rafique Ahmed. The two researchers used data collected by the Bangladesh Meteorological Department.
With more and more land under cement and concrete, squeezing out non-urban areas, runoff after heavy rains has increased 25-33 per cent. The study was carried out over 13,400 ha of Dhaka city, of which 66 per cent was built-up area.
