Sediment control solutions in the best management practice (BMP) toolbox are plentiful today. Both natural and manufactured options exist. Selecting the proper solution for a project can be challenging at times because there are so many choices.
One key factor of sediment control products is whether or not they allow stormwater through them. Sediment control products can be separated as damming and filtering products. Filtering products are defined as those with a flow rate of ≥35 GPM/ft2 according to ASTM D5141. Damming products are designed with a flow rate of <35 GPM/ft2. Matrix density is also an important factor to consider that is related to the flow rate of the sediment control solutions.
Damming and filtering products react differently during hydraulic events. As a result, the products have their limitations and are not interchangeable. Benefits of each type of sediment control products will be discussed along with performance differences in various applications.
