Straw bales are commonly used in roadside ditches as ditchblocks to reduce water velocity and erosion. However, in ditches with high water velocities or intense floods, the straw bales often become damaged needing repair or replacement. In 1987, a new product called "Janridge Barriers", was introduced as an alternate to straw bales. These barriers are made of steel mesh and were installed on a steep (6.5% grade) and flat (0.7% grade) ditch in the Calgary and Grande Prairie districts respectively. Their performance was monitored for four years and were compared with straw bales which were installed next to each Janridge Barrier test section. This report summarizes the results of this evaluation and concludes that janridge Barriers were effective in low grade ditches. An alternative erosion control measure is needed for ditches with higher grades. Based on the findings, it is recommended that janridge Barriers be considered for areas where straw bales would need frequent replacement. (A)
