Rip rap specifications

Average velocity of water approaching the rip rap.

Specific gravity of the rocks to be used, ranging from 2.5 to 3.0.

Results

Enter your values above. The results appear here as soon as there is enough information to calculate them.

How to use the Rip Rap Calculator

  1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
  2. Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
  3. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
  4. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

averageRockDiameter = (waterVelocity ^ 2)/(2 × gravitationalAcceleration × (IsbashConstant ^ 2) × (specificGravity - 1))

volume = area × depth

totalVolume = volume × (1 + wastage/100)

weight = totalVolume × density

cost = pricePerWeight × weight

Frequently asked questions

What is a Rip Rap Calculator?

A Rip Rap Calculator is a specialized tool designed to help users determine the amount and type of rip rap stone needed for erosion control or shoreline protection projects. By inputting specific measurements and desired coverage depth, users can receive an accurate estimate of material requirements.

How do I use a Rip Rap Calculator?

To use a Rip Rap Calculator, you typically need to input key data such as the length, width, and depth of the area to be covered. The calculator will then output the total volume of rip rap stone required, often measured in cubic yards or tons, depending on the specific setup of the calculator.

Why is rip rap important for shoreline protection?

Rip rap serves as an essential erosion control measure for shorelines and riverbanks. It absorbs wave energy and prevents soil erosion, thus preserving the integrity of shorelines, protecting property, and maintaining habitat for aquatic life.

What types of rip rap are there?

Common types of rip rap include granite, limestone, and concrete rubble. Each type has unique properties that make it suitable for different environmental conditions and project goals. Selecting the right type is important for effective erosion control and durability.

Can a Rip Rap Calculator account for different stone sizes?

Yes, many advanced Rip Rap Calculators allow you to specify different stone sizes. The size of the rip rap can affect the volume needed, so accounting for this variable ensures a more accurate estimation for your project.
