Show not necessarily produce 55 a ( two-foot twofoot ) depth of water on riffles and sandbars . On account of the changes in slope of a river , and changes of width at different places a rise of two feet at any one place did not necessarily mean that there would be a ( two-foot twofoot ) rise at any other place . Given the ( same saine ) hydraulic conditions , the same cross section , and the same slope at another cross section , there would ( prob prob- prob ) ably be the same ( two-foot twofoot ) rise . But if you increase your width , or change your slope , ( you yogi ) change the height to which the water will go . The amount of silt or sediment carried or ( trans trans- trans ) ported by a river , depends largely on ( velocity -velocity velocity ) . If velocity at riffles is high enough to send forth all of the finer silt and sediment which when water , reaches quieter stretches they are deposited in the quieter stretches and remain there until velocities increase during flood periods and carry them to some other place . He has studied official reports of experiments made on Colorado River and character of material in Colorado River varies from fine sediment to gravel like that carried ( in iia ) the San Juan ; it varies at ( different differelit ) periods of the year depending on floods from the higher portions of the river in snow ; or from lower stretches of the river from rains etc , . , changes character of silt .
