Quotations and references, taken from old texts on stream channel works (today classified as belonging to soil bioengineering interventions), are presented and discussed. Part I of the same study previously showed a similar analysis on slope stabilization [Bresci 2002]. The selected quotations are reported in a chronologic order to highlight the historical evolution in each work description and, in particular, the instructions and adjustments to put on when carried out. Where suggestions for vegetation material selection and numerical indications are found in the analyzed texts, they have been reported translated into English. The selection of the analyzed works has been carried out among those utilized for streambank protection, a sector where more often vegetation is utilized. Also in this case (Part II) it is demonstrated that bioengineering techniques clearly originate from forest watershed management.

The objective of this study was to evaluate the input of suspended sediment from the slope toe in the São Francisco River channel, in Northeast Brazil, under different soil bioengineering techniques. Sediments were collected in the years of 2013, 2014 and 2015, in five transects crossing the river channel. Sediment input in the sampling points was higher in the year of 2013, i.e., the year of the highest river discharge. Sediment supply to the river channel for a period of 3 years (2013, 2014 and 2015), was evaluated at 20, 40 and 60% depth, along five different transects (P1= riverbank, P2= beginning of the thalweg, P3= middle of the thalweg, P4= end of the thalweg, and P5 = margin of the side sandybar), oriented by the presence or absence of erosion control techniques (treatments) such as: 1-Natural Vegetated Slope; 2-Vegetated Riprap; 3-Eroded Slope; 4-Live Cribwall and 5-Vetiver grass Contour Line. Sediments input was different in all evaluated transects, and the one identified as Eroded Slope at 20% depth presented the lowest amount of suspended sediment load. There was a decrease in the total amount of suspended sediment in the evaluated periods, probably due to the progressive decrease in the river discharge, and the protection provided by the soil bioengineering techniques.

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

Abstract. In the last few years "D. I. A. F." (Department of Agriculture and Forestry Engineering of Florence University), has been testing the effectiveness of soil bioengineering techniques in Central America. The focus of the present study was to find out which native plants were most suited for soil bioengineering purposes, particularly in the realization of riverbank protection in Nicaragua. Furthermore, we have also been aiming at economic efficiency. These techniques are appropriate for sustainable watershed management especially in underdeveloped countries. Concerning the plants to be used we experimented four native species. Gliricidia Sepium, Cordia dentata and Jatropha curcas are suitable for soil bioengineering more than Bursera Simaruba. Economically speaking, the sustainability of such interventions in underdeveloped countries, has been shown by the evaluation of the cost of riverbank protection using vegetated crib-walls in Nicaragua compared to the cost in different contexts.

Os objetivos deste trabalho foram analisar as alterações da paisagem promovidas pela erosão marginal e verificar a eficácia da técnica de bioengenharia de solos na recuperação das margens de um trecho do rio Paramopama, localizado no município de São Cristóvão, estado de Sergipe. Para a avaliação da alteração da paisagem, classificada como de altíssimo, alto e baixo grau de antropização, foram analisadas séries fotográficas compreendidas no período de 1998-2008. As espécies que se estabeleceram com maior ocorrência foram as pertencentes à família Poaceae. Dentre os fatores responsáveis pela alteração da paisagem, destacaram-se a erosão e a instalação de dutos atravessando a calha do rio. No rio Paramopama, foram observados dois momentos distintos, um com altíssimo e outro com alto grau de antropização. A técnica de bioengenharia de solos mostrou-se eficiente no que se refere à recuperação da paisagem, além de prover condições para a recuperação do ecossistema ribeirinho.Palavras-chave: Margens de cursos d´água; recuperação de paisagem; antropização. AbstractRiverine landscape changes: case-study of Paramopama River, Sergipe State. This work aimed to analyze current changes caused by riverbank’s erosion, as well as to verify the effectiveness of soil bioengineering techniques on the landscape recovery applied to Paramopama River banks. In order to verify landscape’s changes, it analyzed a photographic set produced during the period of 1998-2008, which had been classified according to its degree of anthropization as very high, high and low degree. Species with higher occurrence were those belonging to botanic family of Gramineae. There were many factors to landscape change, erosion was the most important followed by disturbances caused by ducts installation across the river channel. At Paramopama River two different moments could be observed, firstly, a very high degree of anthropization followed by a high degree of anthropization. Soil bioengineering technique was efficient to landscape recovery, providing ecological conditions to ecosystem recovery.Keywords: Stream banks; landscape recovery; anthropization.

Abstract. In the last few years "D. I. A. F." (Department of Agriculture and Forestry Engineering of Florence University), has been testing the effectiveness of Soil Bio-Engineering techniques in Central America. The focus of the present study was to find out which native plants were most suited for soil bio-engineering purposes, particularly in the realization of riverbank protection. Furthermore, we have also been aiming at economic efficiency. In the context of sustainable watershed management, these techniques seem to be appropriate, especially in underdeveloped countries. Concerning the plants to be used, we considered three native species, Gliricidia Sepium, Cordia dentata and Jatropha curcas, to be appropriate for this type of work. Economically speaking, the low cost of such interventions in underdeveloped countries, has been shown by the construction of riverbank protection using vegetated crib-walls in Nicaragua.
