In 1992, engineers began protecting 55 km of Ottawa River shoreline with local rounded gravel. 19 years later, 80–90% of the banks were covered by indigenous vegetation

Ottawa River banks were protected using rounded granular material over fifteen years ago. This method halted erosion and created a riparian ecotone with natural vegetation. The structures blended into the landscape, forming a gently sloping shoreline with sandy beaches. Vegetation recovery reached ninety percent, showing plant diversity similar to unstabilized areas. This approach offers an environmentally sound alternative to traditional erosion control techniques.
