Soil bioengineering in northeastern Brazil: An Overview

This article presents an overview of the application soil bioengineering techniques, also modeled as natural engineering, in state Sergipe, northeastern Brazil, showing importance integrating living and inert elements to protect river banks from erosion. The employed techniques are different, ranging characterization susceptibility erosion use biotechniques, considering knowledge areas agronomic forestry civil biology, pedology, geology, geomorphology geotechnics. It is approach that uses methodologies a multidisciplinary way, seeking maximize synergies (for example, engineering combine materials ways help plants develop increasingly efficient systems). considers maintenance-cost optimization conduction works, using different materials, differing traditional which predominantly materials. research work carried out locations sought availability local such rocks, geotextiles made fibers native flora or even available on market, addition species recovery slopes, according ecological conditions Brazil. Size technological reach were considered, biotechnical aesthetic objectives adapted situations.
