<br />~ <br />I <br />, <br /> <br />Gabio.l Revetment <br /> <br />Gabions can be used to stabllize stream banks in nearly every situation, <br />Gabions consist of wire baseets filled with rock, Bank protection using <br />gabions can be constructed Jsing either a mattress revetment or a retaining <br />wall. The installation of .~abions must consider the potential scour depth in <br />the channel. The gabion ba.kets usually require a filter between the baskets <br />and the base material. The filter can be either a sand or gravel filter or a <br />filter fabric. If a mattre.s revetment is used, the banks should be shaped to <br />a slope no steeper than 1 h"rizonal to 1 vertical prior to 'placing the <br />gabions, If a retaining wall is used, the banks may be vertical. <br /> <br />Maintenance requirements foe this practice include inspecting the gabion <br />baskets and repairing any beoken wires. <br /> <br />~ <br />~ <br />~ <br />~ <br />~ <br />j <br /> <br />. <br />. <br />~ <br /> <br />l <br /> <br />, <br /> <br />l <br /> <br />'iR <br />
