Revisão de técnicas para estabilização de taludes afetados por erosão continental

Abstract

The damages and losses of the erosive processes are known by everyone, therefore, it is of fundamental importance to study this kind of degradation. This work aims to present a literature review involving the main practices of prevention, restraint and recover of the erosive processes from hydric cause. The human being, when carrying out the activities of living, transportation e food production, speeds up the natural erosive process. The withdrawal of the vegetal cover, which is the main passive factor in the erosive process, is almost inevitable when doing this activities. Associated to other factors, such as land declivity, length of ramp, soil erodibility, erosivity of the rain, inadequate soil management, can initiate the erosive process. The erosion is characterized for the degradation and soil particle transportation, the deposit of the transported material can also be part of this process. The anthropic intervention in the erosive processes can occur as prevention, advance control and area recovery. The prevention, besides preserving the environment and avoid risks and trouble to the population, it is also the less onerous intervention mode. The success of the erosion combat depends on local conditions, which means it has to be adapted to climate, provide the improvement of soil and objective the rain water disciplinary.
