“…For instance, sample S5 has the highest [CO 2 ]/[O 2 ] ratio and also the highest increase in oxygen rich compounds. The activity of communities of microorganisms is also influenced by the pH (Berg and Laskowski 2005;Rousk et al 2010;van Roon 2012), and, since S5 is acidic while the other samples are close to neutral, the active microorganisms can differ which also explains the difference in [CO 2 …”

Functional properties of soils formed from biochemical ripening of dredged sediments—subsidence mitigation in delta areas

et al. 2016

Purpose In delta areas, dense networks of canals have been developed through time and have to be periodically dredged. Lowering the groundwater level in delta areas deepens the aerobic zone, leading to the oxidation of organic matter and possibly to land subsidence. The use of the dredged sediments on land can be a solution to mitigate land subsidence in delta areas. Materials and methods Five types of dredged sediments with different organic matter content and particle size distribution were dewatered for 7 days and then submitted to biochemical ripening during 141 days on a laboratorial scale with constant temperature and relative humidity. The functional properties analysed were the type and content of organic matter, pH, total C, N, P and S, dry bulk density, water retention capacity, aggregate stability and load-bearing capacity. Results and discussion After biochemical ripening, there was no significant loss in the mass of organic matter but there was an increase in the fraction of stable organic compounds, observed by an increase in oxygen-bearing compounds and a decrease in hydrocarbons during biochemical ripening. The pH was not affected by biochemical ripening, and the total C, N, P and S concentrations are high and therefore the dredged sediments can improve the quality of the land. Most volume lost during dewatering and biochemical ripening can be attributed to the loss of water. The water retention capacity of the dredged sediments changed with biochemical ripening. The soils formed from biochemical ripening have very stable aggregates, and its load-bearing capacity is enough to sustain cattle and tractors. Conclusions Most volume lost during dewatering and biochemical ripening can be attributed to the loss of water and not organic matter. Therefore, the studied dredged sediments have potential to mitigate land subsidence in delta areas when spread on land.

“…In addition to the methodological procedures consolidated in the framework proposal, the results presented below constitute a demonstration of the proposed new urban design applied to the space occupied by the Vila Cascatinha community. In spite of being innovative, the sustainable urban design is entirely in alignment with the international methodologies for addressing urban spaces ( VAN ROON, 2012).…”

“…Among the innovative drainage elements used in low impact development are: infiltration trenches and wells, water tanks and cisterns to store rainwater, green roofs, bio-retention ditches, infiltration and evaporation beds and walkways with permeable paving and the protection and restoration of wetlands in city areas such as marshland, bogs and mangrove swamps (BRACEY et. al., 2008;VAN ROON, 2012).…”

The paper presents a methodological proposal in the form of a framework for redesigning informal settlements based on Low-impact Design and Development methodology. It involves the management of rainwater through the implementation of urban infrastructure on local scale in a decentralized and collaborative manner. It served as an object of study the region of Baixada de Jacarepagua, a vector of expansion of the city of Rio de Janeiro. The proposed framework adopts Action-Research methodology. The stages envisaged in the framework are: (i) initial, which involves approaching the community, establishing bonds and setting up a management group, (ii) diagnosis, and (iii) project. The application of the framework is demonstrated by means of a case study of the community, which typifies the slums in areas of marshland and the peripheral urban landscape. It is believed that this framework can guide the urban redesign of other communities within the perspective of sustainable development.

ResumoEste trabalho discute o papel dos telhados verdes no desenho e desenvolvimento urbano de baixo impacto ambiental. São aprofundadas as questões relacionadas ao manejo das águas pluviais urbanas e é avaliado o desempenho dos telhados verdes como dispositivos nos sistemas de micro e macrodrenagem. A metodologia envolveu a aplicação de modelos computacionais hidrológicos-hidráulicos através de estudo de caso em bacia hidrográfica localizada em área de paisagem periurbana na cidade do Rio de Janeiro. O modelo computacional adotado, SWMM da US-EPA, permite que se insira de maneira hipotética estes dispositivos em edificações pré-existentes. Através do estudo de cenários sem e com inserção de telhados verdes, pode-se avaliar virtualmente o papel destes dispositivos na redução dos volumes escoados superficialmente e da vazão instantânea máxima, assim como das condições de extravasamento da calha fluvial sob chuva intensa real observada no local em abril de 2010. Os resultados permitiram verificar que apesar de não reverter o extravasamento da calha fluvial, os telhados verdes tiveram impacto na redução dos volumes escoados superficialmente, que agravam as enchentes urbanas, e da vazão máxima instantânea em até 10% aproximadamente. A partir destes resultados e da avaliação das outras sinergias dos telhados verdes com o desenho e desenvolvimento urbano de baixo impacto ambiental recomenda-se o incentivo de políticas públicas que possam viabilizar sua adoção nas cidades Brasileiras com vistas à melhoria da qualidade de vida da população que habita os aglomerados urbanos.

Evaluation of the implantation of green roofs in urban basins to control surface runoff: a case study in the basin of the Morto river, Rio de Janeiro AbstractThis paper discusses the role of green roofs in the low impact urban design and development. The issues related to urban storm water management are deepened and the performance of green roofs is evaluated as devices in micro and macro drainage systems. The methodology involved the application of hydrologicalhydraulic computational models through a case study in a catchment located in peri-urban landscape area in the city of Rio de Janeiro. The adopted US-EPA SWMM model allows these devices to be hypothetically inserted into pre-existing buildings. Through the study of scenarios without and with insertion of green roofs, the role of these devices can be evaluated in the reduction of the volumes surface runoff and the maximum instantaneous stream flow, as well as of the conditions of river flow floods under real intense rain observed in April 2010. The results showed that, despite not reversing the river flow floods, the green roofs had an impact on the reduction of the volumes surface runoff, which aggravate urban floods, and the maximum instantaneous flow rate up to approximately 10%. From these results and the evaluation of the other synergies of the green roofs with the low impact urban design and ...
