EROSION CONTROL AND REVEGETATION TECHNIQUES USING MECHANICALLY STABILIZED EARTH SLOPES

Revegetation and erosion control techniques on reinforced one-to-one slopes were monitored and reported. Two 15 foot (4.6 m) high embankments were constructed with reinforced one-to-one slopes. These four slopes were each finished with six revegetation test sections. The test section characteristics provided a broad range of aesthetic and economic examples. The test sections were monitored for vegetation success and eroded material. The study was conducted in a semiarid climate. It is concluded that: 1) Irrigation commensurate with evapotranspiration rates and precipitation will be necessary in semiarid climates; 2) Slope orientation will have an impact on revegetation success; 3) Any of the studied revegetation test sections offer excellent erosion control; and 4) Vegetated one-to-one slopes can offer the designer an aesthetic and economic alternative to vertical retaining walls.
