River: There is a nabaganga river in the madakalai pagalankai. River length 3 kilometers Due to river erosion, there are several variations of these rivers.

 

River corrosion

The river breakdown is a regular disaster in Bangladesh. Damage to river erosion gradually, but is more devastating and far-reaching than other sudden and flaming disasters.

Causes of river breakdown: Natural

    Because Bangladesh is a sedimentary land, it is easily broken by the flow of water in the land of the river or by slight tread.
    If soil structure is weak, then there is a slight pressure or a blow to the river.
    The sudden flood or sudden river erosion in the north and northeast of the country due to the sudden flooding occurs.
    During the rainy season or flood, the amount of water gets increased in the river, which is due to increased water pressure and there is a river erosion.
    There are many times river erosion in the river erosion.
    Where the river has changed its course, there is a river breakdown on the left.
    When the river is divided into many branches, there is a break in the middle of the chars.
    The river size is also a cause of breakdown, because the disruption of the big river is high.
    Soft clay soil at the bottom of the river, due to melting through the water flutter, flows downwards, and the upper hard soil collapses first and then collapses.
    Due to the flooding of the river, excess pressure is created on the shore while the growth of the water and the bridges are broken.
    Due to tidal flow in the river, breakdown occurs due to the flow of water.
    There is a breakdown in the river due to the creation of new chars or other natural causes due to obstruction in the normal course of the river.
    If the flow of the river increases with the increase of the flow of water, the flow of the ball or the water in the form of water is also broken.
    Due to excessive rainfall, there is a lot of disruption in the river.

Reasons to break the river: Man-made

    Due to the construction of cross-country dams in the middle of the river, there is a breakdown in the side effect as a result of trying to stop the river motion.
    Due to river erosion or breakdown of land in the breakdown area or due to the breakdown of the river from the river side or due to the construction of a flood prevention dam, the river erosion occurs.
    By creating unplanned road-dams and dams, due to the inhibition of monsoon rain water, the water pressure in the rivers increases and the intensity of breakdown increases.
    As a result of the efforts of people to change the course of the river irrationally, river erosion occurs.
    In order to protect the city, construction of high dams on one side of the river, and due to the prevention of preventive measures, the disturbance of another river is created.
    Suddenly, due to the sudden obstructing of excess water, due to the obstruction of the river's source, there was a sudden breakdown on the river bank.
    Construction of sluice gate, due to water pressure in the name of water control, due to increase in water pressure, river erosion is broken.
    Due to the destruction of grazing forests and rams forests, there is a break on the side of the grazing.
    There is also a river erosion due to ferries or navigation.
    Due to irrational dredging or river erosion, there is a river erosion.

The consequences of river erosion in society

 

    River breaches cause unemployment and poverty.
    Land erosion increases due to river erosion.
    In the face of lack of resources, in the face of lack of conspiracy or pressure of others, the remaining people are left out of the land, livestock and other valuable items.
    Many families / people are heavily indebted.
    The damaged people are falling into insecure situations.
    There is a severe crisis of drinking water and sewage.
    Women's personal or physical insecurity is created and women's persecution increases.
    A large number of people leave the area and move temporarily or permanently to the city or any other place in the hope of getting employment or survival.
    Alimony spread among old people, women and children.
    Due to binded writing and school closure, many children once left school and can not return to school, thus increasing the untrained population in the population.
    Hundreds or thousands of people are forced to live their lives in a unhygienic environment in the dam or city slum.
    Children in river erosion are thrown into unfavorable conditions and unwanted surroundings in dams or slums.
    Public-poverty broadly spreads malnutrition.
    Child labor and child abuse increase.
