Role of Vegetation in Stabilising Natural Slopes

Role of Vegetation in Stabilising Natural Slopes

Introduction

The modern development of existing roads, such as canals, roads and railways, as well as the impetus for the construction of earth dams, and development of protective works against the action of rivers have been the design and construction of embankments on a level of engineering importance of the first order (Donald & Robbin, 1996). Both the investment aspect, for the consequences of their fails, the banks are now one of the most rigorous engineering structures cares by the designer. With the expansion of channels, rail and roads, triggered the first attempts to make a rational study in this field, but it was not until the advent of Soil Mechanics when he was can be applied to the design of embankments and criteria. These standards and criteria point directly to the durability of the slope; this is their stability over time.

Discussion

Geology and Geo technology

Slope Means any inclined surface slope from the horizontal they adopt permanent earthen structures. There is no doubt that the slope is a complex structure to analyze because in their study match the problems of soil mechanics and rock mechanics, not to mention the basic role that geology plays in the formulation of any criteria acceptable. When the slope occurs naturally, without human intervention, is natural slope or simply called slope. When the slopes are made by the man called slices or artificial slopes, as the genesis of their training; in cutting, digging is done in a natural, natural formation (clearings) in while the artificial slopes are the slanted sides of the embankments. In some civil engineering, work is necessary to use the soil as slope as part of the work. Such is the case in road embankments road from dams land, channels, etc, where required to study the stability of the slope. In some cases, the stability plays a role very important in the work, determining the existence thereof as may be in earth dams, where a miscalculation can derail the work (Lee, 2002, 563). The result of the slide of a slope can often be catastrophic, with considerable loss of property and many lives.
