WebHaving drawn your cross-section by ‘joining the dots’ on your graph you have created a scale picture of a slice through the river. This diagram can be used to calculate the cross-sectional area or wetted perimeter of the river, which are needed to find discharge and channel efficiency. You can calculate the area by using graph paper or use ... Webfriction velocity of surficial sediment in 2004. The tidal friction velocity was lower than the sediment threshold friction velocity in 2004, so it is concluded that the erosion active force became interactive of wave and tide. Wave is to move the sediment and tidal flow is to transport sediment mainly.
