It is a common misconception that a silt fence can be used to filter heavy, concentrated flows of water in streams or drainage ditches. In reality, these barriers are specifically engineered to handle low-velocity sheet flow across flat or gently sloping surfaces rather than concentrated channels. When subjected to the immense force of concentrated water flow, the fabric can quickly become blinded by fine particles, leading to a complete blockage that causes water to overtop or destroy the structure. Using this barrier in a high-flow channel usually results in catastrophic failure, washing the sediment directly into protected water systems. For concentrated flows, engineers utilize alternative sediment control measures such as rock check dams, sediment basins, or specialized turbidity curtains.
