Very high or low rainfall Sea level rise Changes in river sediment transport and flood regimes Disturbance in requiring long periods of adjustment in fluvial processes and morphological forms Rapid morphological change in river for the exceptional change in water level caused by sudden rain fall Change in soil moisture due to shifting rainfall Change in seasonality

Change in River Morphology

Rapid change in river morphology cause massive riverbank erosion at the up stream of the Bangabandhu Bridge (Courtesy: CEGIS)

Indigenous Adaptation Techniques

Bamboo pilling (85%)

Sand bag filling (80%)*

Temporary house (60%)

Bandaling (10%)*

Abstract ID: ISCC 11139

Migration in different location (90%)*Moved toward char land (20%) Natural vegetation cover for erosion protection (30%)Moveable assets such as cattle instead for permanent asset like pacca house (65%)

* Percentage (%) on the basis of local people’s perception for adaptation to riverbank erosion

All the photographs and data were collected during field survey in 2010
