Weather elements such as wind, rain, snow, and sunshine usually have adverse effects on landscape. One of these effects is slope instability. Slope instability is characterized by downward drifting of loose topsoil, leading to the formation of a hole or gulley behind. This situation can be made started or made worse by weather elements, human activities, or natural processes. If not controlled, slopes that are unstable only get worse and can become a major safety hazard. Here are facts regarding Slope stabilization.
If slope instability happens on roads, the roads may be rendered unfit for use or they may be a major source of accidents. Ensuring the slope is stabilized may be the best solution for such a situation. Several measures can be put in place in order to ensure that soil erosion is stopped right away or gradually. There are many methods that produce good results immediately and those that take longer to yield good results.
Several methods have been invented for use in stabilizing slopes. They may be used alone or in combination to achieve the desired results. Some of these methods include terracing, diversions, grassed waterways, conservation ponds, retaining walls, drop structures, sobo dams, trail improvement, and gully control among many others. Applying several methods together achieves better results better and faster.
Slope stabilisation and erosion control can be broadly curbed by one approach known as terracing. This involves aligning the landscape with a continuation of structures designed like steps so as to curb how runoff occurs. The runoff is guided to an appropriate outlet by the steps to moderate speed, preventing erosion. Soil erosion is minimized generally as runoff soil is trapped on the terrace.
Another method that is used commonly is the creation of diversions in the slope. Diversions are usually constructed across slopes so that they can intercept the runoff and dispose it at a specified location. The purposes of diversions include breaking up long slopes, directing water away from active sites of erosion, directing water around agricultural locations, and/or channeling runoffs to suitable outlets.
The safest and simplest approach of having springs drained off is applying open ditches. Digging the primary ditch is the first step in using open ditches. The ditch location must be in similar direction as the gradient of the slope. One then digs smaller ditches from the main ditch. A fishbone pattern should be used when digging the smaller ditches. Secondary and tertiary ditches must be included in the deign.
Water from the ditch should be collected as close as possible to its origin. From there, it can be channeled to a culvert, side drain, or a water course nearby. Gravel or stone should be placed at the bottom of the ditch to prevent erosion of the bed. One can also use pipe drains because they are more efficient, although they can be a bit expensive. Since stones are likely to silt up over time, one should ensure that drainage is effective.
Slopes can be best stabilized by planting grass along waterways. Grass may grow naturally or it may need to be grown. This not only applies to grass but also to other appropriate vegetation. Before vegetation is planted, the surface should be prepared well. Vegetation serves to make soil harder and firmer so that it cannot be carried away easily by water.
