What Is The Cross Sectional Area Of A River

Cross sectional area width x average depth m2.

What is the cross sectional area of a river. Producing a cross section of a river channel is a basic river fieldwork skill. Discharge area x velocity. Along a river reach of about 150 km cross sectional area correlates strongly with curvature.

Braided channel cross sections can be created by entering land as negative data. Download an image of your cross section and print the data calculations used to construct and analyse it. What is cross sectional area of a river answers.

The data can then be plotted to create a scale diagram of the cross section or used to find the cross sectional area and wetted perimeter of the river. In 3d you have length breadth and height but when you go for cross section there are only two dimensions one is breadth and other one is your height with respect to the direction of length if you go with the direction of breadth then the cross. A long waterproof tape measure is needed to find the width of the river.

Google mannings equation for a more precise equation. Start from one river bank and move at 30cm intervals across the river. The first stage is to measure the width and depth of the river.

Measure the depth and the width of the river. Cross sectional area csa m2 this is a simple calculation to measure the amount of water at each site the cross sectional. Multiply the depth by the width to find the cross sectional area.

In general river discharge is computed by multiplying the area of water in a channel cross section by the average velocity of the water in that cross section. Enter your river data to quickly make a river cross section and calculate the cross sectional area wetted perimeter and hydraulic radius. Whether you need to find the discharge or examine the profile of a feature such as a meander or riffle it will be necessary to produce a cross section of the river.
