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
