Understanding and Implementing Seven Modes of Sediment Control

Dwayne L. Stenlund, M.Sc

Sediment control is commonly understood as silt fence that operates as a sedimentation best practice. The 2020 IECA annual meeting had many excellent presentations that focused on new design tools (award paper of the year), performance testing, and utilization. This created significant interest as understanding how a highly regarded sedimentation mode of practice actually works to control sediment from upgradient exposed soil sources. However, this is only one of seven modes of sediment control that require investigation of best practice, and commensurate design for project implementation.

• Understand different types of sediment control modes of action as BMP systems.
• Incorporate various sediment BMP modes into the project SWPPP.
• Recognize proper sediment control by functional mode type for installation, maintenance, corrective actions.
