“…Since carbonate can play an important role as a binder of soil, the content of carbonate becomes one of the most important factors to evaluate the mechanical properties of soils cemented in natural or artifi cial process (Fukue et al 1999(Fukue et al , 2011. In this study, the averaged carbonate content of soil (C) is defi ned by…”

“…Most carbonate diagenesis is in the category of the bio-cementation process, which is well known as the formation of limestone. In fact, any marine sediment contains some carbonate, which is used in the carbonate diagenesis (Fukue et al 1999). This suggests that soils can be strengthened by precipitating carbonate, regardless of natural or artifi cial processes.…”

Concept of hybrid embankment. An innovative technique which is similar to a natural process, i.e., biogeochemical (carbonate) diagenesis, is proposed to construct a hybrid embankment. In this study, the hybrid embankment is defi ned as a soil embankment which has a microbially induced framework structure of sand sheets and columns in the soft soil matrix. The sand materials are cemented with magnesium-calcite or dolomite, induced by ureolytic microbes. To design and construct hybrid embankments, fundamental problems, such as feasibility in terms of stability, geoenvironmental engineering practices, etc., are examined and discussed. It was shown that the hybrid embankment can be environmentally friendly and also can contribute solving technical and fi nancial problems encountered in actual practice.

Knowledge about the hyporheic zone is important to understand the pollutant attenuation processes that occur during the aquifer recharge, whether by natural or artificial means, for example, Bank Filtration. In this paper, the structure of the hyporheic meiofauna and the influence of pollution, microphytobenthos and sedimentological parameters (grain size, organic matter and CaCO 3 content) were studied at a periurban area of Beberibe River (Northeastern Brazil), the location of a riverbank filtration (RBF) pilot project. PERMANOVA analysis indicated interactions between meiofauna community and the sampling sites, rainfall seasons, and depth. The release of untreated wastewater was the most influential factor for physical and biochemical features of the hyporheic zone, since the sampling sites with higher levels of elements related to eutrophication supported the highest levels of meiofauna abundance, fine sediments, organic matter, and CaCO 3 content. It was verified that organic matter from domestic wastewater in tropical streams can promote protective effects that favor the retention and biodegradation of pollutants in the hyporheic zone. The results reveal that, even in eutrophic rivers, there are factors that contribute to the processes of pollutant attenuation in tropical hyporheic environments. The results demonstrate the potential for using RBF in communities without adequate sanitation, especially in developing countries.
