Enter the total change in depth of sediment (in) and the total time (yr) into the Erosion Rate Calculator. The calculator will evaluate the Erosion Rate. 

Erosion Rate Formula

The following two example problems outline the steps and information needed to calculate the Erosion Rate.

ERR = DP / T

  • Where ERR is the Erosion Rate (in/yr)
  • DP is the total change in depth of sediment (in) 
  • T is the total time (yr) 

How to Calculate Erosion Rate?

The following example problems outline how to calculate Erosion Rate.

Example Problem #1:

  1. First, determine the total change in depth of sediment (in). 
    • The total change in depth of sediment (in) is given as: 20.
  2. Next, determine the total time (yr). 
    • The total time (yr) is provided as: 5.
  3. Finally, calculate the Erosion Rate using the equation above: 

ERR = DP / T

The values provided above are inserted into the equation below and computed.

ERR = 20 / 5 = 4 (in/yr)

Example Problem #2: 

For this problem, the variables required are provided below:

total change in depth of sediment (in) = 60

total time (yr) = 10

Test your knowledge using the equation and check your answer with the calculator

ERR = DP / T = ?
