Flood actually elevate land a few milimeter as fine slit cover the land once water recedes. The river silt which get deposited in the estuary causes land mass gradually to enlarge in the coastal region. This is how the entire southern region of Bangladesh was formed over many thousands of years. This process is still continuing and coastal areas are expanding by an average 20 sq. km per year. To learn this process more thoroughly you can study about how deltas are formed.Yes Bangaldesh is gaining so much land. It will double in size in next few years
Of course Bangladesh is gaining land. Just because Sylhet region is experiencing heavy flood does not refute this truth. Land expansion is happening in the southern coastal region while flood is happening in the northeastern side of Bangladesh. These two areas are separated by a few hundred kilometers.I am not I am responding the claims certain bengali members have been making in other threads that BD is gaining land.
