Translate the following text into Bangla:
Bangladesh is one of the largest deltas in the world, formed with the fertile silt washed down from the Himalayan highlands by some of the mightiest rivers of Asia, notably, the Ganges and the Brahmaputra. These rivers, together with their countless tributaries, sweep across the vast basin in a bewildering tangle of channels and streams. Acting as arteries, this complicated hydrography is largely responsible for shaping the destiny of the land and its people. While flowing downwards from the melting snow of the Himalayan glaciers, these streams deposit enormous volumes of fertilising silt before spilling into the Bay of Bengal. The rich alluvium of the rivers enriches the land and sustains a teaming population. The same rivers often change their courses and engulf many human settlements located on their banks and cause untold miseries to the people during devastating floods. The rivers are, therefore, the sources of both joy and sufferings to the people of Bangladesh.
