What is Riprap Weight?

Riprap weight is the weight of the rock or other material used to protect shorelines, streambeds, bridge abutments, pilings, and other structures from erosion. It is calculated based on the dimensions of the riprap and its density.

Example Calculation

Let's consider an example:

Using the formula to calculate Riprap Weight:

\[ RW = \frac{10 \times 5 \times 12}{12} \times 156.07 = 7803.5 \, \text{lbs} \]

This means that the riprap weight for the given example is approximately 7803.5 lbs.
