Erosion control is basically the practice of controlling soil erosion by restricting the activity of various agents which contribute to this damaging activity. Right from agriculture to construction, every sector is affected by this natural hazard, and that has prompted people to resort to various measures of keeping a check on these agents of erosion.
The most prominent agents of erosion are water (surface flow and underground water), wind (most prominent in deserts), waves (restricted to the seashore), and ice (restricted to cold mountainous regions and polar areas).
The fact that wind erosion and glacial erosion are restricted to certain zones makes them less important as compared to water erosion and wave erosion.
That being said, we need to opt for soil conservation methods as an effective tool to counter water erosion. One of the most effective ways to conserve soil is to plant vegetation.
Slopes are most vulnerable to erosion by surface water runoff. In order to curb such erosion, the best measure is to plant trees along the slope.
Planting creepers is a definite advantage, as they grow horizontally and thus cover more ground. That, however, doesn't mean you decorate the entire slope with creepers. Bigger trees have deeper roots which hold more soil together and thus, are quite efficient.
Use of geotextile tubes filled with sand and stones is one of the most popular measures of controlling shoreline erosion. Similarly, breakwater, which is a protective structure made from large stones to prevent the shore from being washed away, is also known to be quite effective and considerably inexpensive.
If not controlled in time, soil erosion can lead to various problems including loss of fertile soil and natural disasters, like land slides.
A slope, which is subjected to continuous erosion, is bound to weaken over the course of time and eventually cause a landslide. If we are to avoid such disasters, the need of the hour is to come up with erosion prevention measures and implement them at the ground level.
