Crossing bars which are known to change are . caused by the washing away of sand and soil on these crossing bars , which is carried down stream to where river changes into a straight channel , where . they are deposited and then build , and then change on account of silt and sediment from these bars as well as from silt and sediment brought in from main stream .
