Jamuna River Erosional Hazards and Rural

Vulnerability in Bangladesh: A Case Study on Sirajgonj District

IntroductionImportance 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.

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.

Problems of the Statement

• Demographic impact• Economic hamper• Biodiversity loss• Human displacement

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.

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

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 meters above sea level.

• Sirajganj has a population of 127,481 making it the 7th biggest city in Rajshahi.

MethodologyPrimary data

• Sources of DataPrimary dataSecondary data

• Data collectionQuestionnaire surveypersonal observation

• Data analysis Microsoft office, Excel, SPSS, GIS

Possible Outcomes• To find out the way to reduce or avoid the

erosion• To identify the major determinant and

characteristics• To show the trends of erosion and accretion of

land along both sides of the river. • Find out the existing situation• To review the policies and laws regarding erosion
