Description : A seasonal boatman helps people in migration. Migration never happens during flood, it happens when river erosion starts. But in Sirajganj, a northern district of the country river erosion and flood come together. Most of the northern district is under threat of flood. People have to move their homes with their belongings and take shelter on the highland. Continuous increase in water level causes inundation of river beds and marooning thousands of people.
