Flood Study on Dhaka City

• A study was carried out immediately after
  flood 2007 with the following objectives
• to explore the causes of the flood 2007
• to investigate the hydrologic aspects of flood
  2007
• to compare Flood 2007 with major historic floods
• to determine the extent of flood 2007
• to evaluate the performances of flood control
  structures around Dhaka city

Temporary pumps near Hazaribag discharge
untreated waste water which cause serious
pollution of Buriganga river

Encroachments gradually increases and reduces
retention pond area of Kallayanpur pump station

Floating mat of waste on Dholai khal indicates
poor solid waste management of the Dhaka city
