No one knows when it happened: some would say perhaps it made no sound, or maybe no one was listening, but something changed in the watershed upstream of several properties in a Noblesville, IN, subdivision. Suddenly, the slope of a streambank in a neighborhood backyard began wasting away.

Hard-Armor Options for Protecting Roads and Bridges

Hard-Armor Options for Protecting Roads and Bridges

Hard-armor products are valuable tools in the tool chest of experts in erosion control and stormwater management. For some applications, softer alternatives such as erosion control blankets, turf reinforcement mats, and vegetation are appropriate. But many roads, bridges, and streambanks face destruction because of undercutting due to runoff or high
