Bangladesh Is Land Of River

Bangladesh may be a land of rivers.River long water course that flows down a slope on a bed between banks. It originates from a 'source' and culminates to a ocean or lake at its 'mouth'. on its length it's going to be joined by smaller streams referred to as 'tributaries'A river tends to eliminate irregularities and forms a swish gradient from its supply to its base level. because it approaches base level, downward cutting is replaced by lateral cutting, and also the stream widens its bed and natural depression and develops a wiggly course that forms exaggerated loops and bends referred to as meander. A stream will open up a brand new channel across the arc of a meander, thereby isolating the arc associate degreed making an lake. stream speed determines amount and size of rock fragments and sediment carried by the stream.
