A river cross section diagram illustrates the different features and layers of a river, including the water flow, depth, and bed composition. Understanding the cross section of a river can help in studying its hydrology, erosion patterns, and flood potential.

The cross profile of a river refers to a section taken sideways across the river channel or valley. There are two main types: Channel Cross Profile: Includes only the river itself. Valley Cross Profile: Encompasses the river channel, the valley floor, and the slopes of the valley sides. How and why does a channel cross-profile change downstream?

Dec 26, 2021 · Figures 5-17 and 5-18 are simplified flow-transverse cross sections through a representative single-channel alluvial river of medium to large size. Figure 5-17 shows the entire stream valley, and Figure 5-18 shows details of the river channel itself.

The current meter is used to measure water velocity at predetermined points (subsections) along a marked line, suspended cableway, or bridge across a river or stream. The depth of the water is also measured at each point.

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 one of many computer programs that are available.

Aug 2, 2022 · You can use the cross-section generator to create cross-sections along the river centre line. Access by clicking the 'Cross Section' button in the 'Map Tools' tab of the main toolbar (it is also available from the Toolbox under Additional Modelling Tools >1D Cross Sections > Cross Section Generator).

Learn about and revise river processes, including erosion, transportation and deposition, with GCSE Bitesize Geography (AQA).

View graphical plots of each cross section, along with reference stations and stages. Calculate and report many common river measurements, including: Transect areas.

The river cross-section is typically divided into subsections (see Figure 1). In each subsection, the water depth and average flow velocity are measured to obtain the water discharge [7,8]. ...
