Ways to Control Erosion on Steep Slopes

Steep slopes are most prone to water erosion. This occurs mainly on the slopes from which the upper fertile soil layer is washed off with meltwater or water from irrigation canals. As a result, ravines begin to form, and very soon the terrain begins to lose its fertile qualities. The rate of erosion directly depends on the steepness and length of the slopes, moreover, destructive processes develop on convex slopes faster than on concave surfaces.

Methods of Securing the Slopes

There are many ways that allow you to strengthen the steep slopes, but they are selected in each case individually, depending on conditions such as the angle of the slope, the proximity of groundwater or the likelihood of washing away in case of a spill.

If the steepness of the slope is small, then planted trees with a developed root system will help prevent landslide processes. They are able to strengthen the soil, protect soils from erosion and strengthen the slope. If the slope is above average, it can be fixed with the help of piles, geogrids, biomats or ceramic stones and blocks. All these technologies are proven, effective and efficient.

Land Reclamation Protection

This method involves planting forest belts on the slopes, arranging canals for diverting meltwater, terracing the slopes, creating dams and artificial reservoirs. The band landing of shrubs across the slope is carried out for this. Protective strips prevent water and wind erosion, they become a reliable barrier to the destruction of the soil. Forest belts are also planted on the upper boundaries of the slopes to protect them from shedding and erosion. These measures make it possible to direct drainage along strictly limited routes and protect the main landmass.

Reinforcing Geomaterials as an Optimal Solution

The most effective solution for strengthening the slopes is the bulk geogrids, stretched and firmly fixed on the soil foundation. Depending on the complexity of the task, the internal volume of the lattice is ballasted with rubble, then it is filled with soil with seeds of perennial grasses. Grass root systems create a durable and weatherproof turf covering that can withstand any erosion. Geo-lattice materials remain in the ground, reinforcing its upper layers and preventing their horizontal movement.

Biotextiles for Landscaping Slopes

Durable grass cover, with a developed root system, is a natural barrier to the formation of water erosion. The turf coating requires almost no maintenance, it tolerates temperature fluctuations and optimal mechanical effects.
