Enter the channel height (ft) and the channel length (ft) into the Calculator. The calculator will evaluate the Channel Slope. 

Channel Slope Formula

CS = CH / CL


  • CS is the Channel Slope (ft/ft)
  • CH is the channel height (ft)
  • CL is the channel length (ft)

To calculate Channel Slope, divide the channel height by the channel length.

How to Calculate Channel Slope?

The following steps outline how to calculate the Channel Slope.

  1. First, determine the channel height (ft). 
  2. Next, determine the channel length (ft). 
  3. Next, gather the formula from above = CS = CH / CL.
  4. Finally, calculate the Channel Slope.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

channel height (ft) = 30

channel length (ft) = 150
