3. Introduction
Importance of river
• Water is the most important natural
resources for planet earth
• The prosperity of nation depends primarily
upon the exploitation of this resource.
• Primary wealth of nation is water which
flow in the river.
4. What is erosion?
As a river flow , the force of its
moving water washes away loose
soil and pieces of rocks. In this way
the river cuts it own channel in the
ground. This process is called
erosion.
5. Problems of the Statement
• Demographic impact
• Economic hamper
• Biodiversity loss
• Human displacement
6. Literature review
• Not only the floodplain inhabitants,
but also the char land inhabitants are defenseless to
river erosion (Aktar, 2013).
• Geomorphic hazards demarcated as the instability of
earth surface features treat that’s threat for human
civilization (Gares et al., 1994).
• The annual monsoons and tectonic settings
dominate the sediment discharge in Jamuna (Rajib
et al., 2011) and (Ashworth, 1996).
• Rahman (1986) conducted to identify the possible
economic strategies of the victims for their survival.
7. Objectives
• To explore migration occur due to
riverbank erosion of the study area.
• To investigate the causes of river
bank erosion in the study area
• To review the potential losses in the
study area
8. Study area
• Sirajganj is a city found
in Rajshahi, Bangladesh.
• It is located 24.460 latitude and 89.710
longitude and it is situated at elevation 19
