Field-Based Research on the Impacts of Climate Change on Rivers

This PDA helped assess the impacts of climate change on Bangladesh's rivers through field-based research.

Report Card

Completed in June 2010, this PDA helped assess the

  • Probable impacts of climate change on the morphological processes of the rivers system (width, bed level, planform, erosion/accretion processes, and flood regime)
  • Effect on riverbank erosion and existing structures
  • Impact of climate change on people in the context of riverbank erosion

Read the final report.


Bangladesh is among the most vulnerable to the effects of climate change, particularly its great rivers. Observations by the Center for Environmental and Geographic Information Services (CEGIS) reveal that the Jamuna and Padma rivers have widened more than three kilometers in the past 30 years, affecting 130,000 hectares of floodplains and displacing more than one million people.

This PDA supported a field research to assess the impact of climate change on the morphology of major non-tidal rivers and its consequences on people and the environment. It assessed the impact of large-scale changes in major rivers and risks of river widening or instability, specifically on existing river training structures and infrastructures near riverbanks.

Expected Outcome

  • Better understanding on the morphological processes of the major non-tidal rivers of Bangladesh
  • Policy makers taking necessary actions in minimizing loses in case of unfavorable morphological changes
  • Increased support to disaster risk management
  • Better trained engineers in planning and designing river training structures
