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 ... WebA large amount of accurate river cross-section data is indispensable for predicting river stages. However, the measured river cross-section data are usually sparse in the …
