Installing riprap (a layer of rock or other material used to protect a slope from erosion) is the most effective means of mitigating the risk of a slope failure in this case. It will provide structural stability to the slope and prevent erosion caused by water runoff. Shotcrete (sprayed concrete) can also provide stability, but it is not as effective as riprap in this situation. Revegetation and dewatering may help to some extent, but they are not as effective as riprap for providing long-term stability to the slope.
