For this methodology were applied as questionnaires and interviews with construction companies to the city, with views fetch results related to the stage of implementation of the management of RCC proposal by Brazilian resolution nº. 307 of the National Environment Council. Also data were collected for analysis in the municipal government sector generator. In this paper we present the results of analysis of perception of construction companies studied in relation to the management of RCC in their worksites and scaling parameter generation of RCC by licensed areas for new buildings along the City of Sao Carlos. For this parameter was concluded that San Carlos passed between the years 2009 and 2012, 2,347,694.93 m² of new construction, which reflects tremendous growth of construction in the city over the past four years. However, this table expansion was not accompanied by efficient management of waste produced in the beds, which can be seen by the increase in annual generation from 63,877.76 tonnes in 2009 to 82,413.38 tonnes in 2012. / Este trabalho apresenta o diagnóstico da atual situação da gestão dos resíduos da construção civil (RCC) em canteiros de obras de empresas construtoras atuantes no município de São Carlos SP, Brasil. Para isso, como metodologia foram aplicados questionários e entrevistas junto às empresas construtoras da cidade, com vistas buscar resultados relacionados ao estágio de implantação da gestão de RCC proposta pela resolução brasileira no307 do Conselho Nacional do Meio Ambiente. Também foram levantados dados na Prefeitura Municipal para análise do setor gerador. No presente trabalho são apresentados os resultados das análises de percepção das empresas construtoras estudadas em relação à gestão dos RCC em seus canteiros de obras e do dimensionamento da geração de RCC pelo parâmetro áreas licenciadas para construções novas junto a Prefeitura Municipal de São Carlos. Por este parâmetro foi possível concluir que São Carlos aprovou entre os anos de 2009 e 2012, 2.347.694,93 m2 de novas construções, o que reflete vertiginoso crescimento da construção civil na cidade nos últimos quatro anos. Porém, este quadro de expansão não foi acompanhado de gestão eficiente dos resíduos produzidos nos canteiros, o que pode ser observado pelo aumento da geração anual de 63.877,76 t em 2009 para 82.413,38 t em 2012.

<div>Disaster debris management is critical to the success of disaster recovery systems. While there are multiple disaster mitigation strategies and post-disaster debris management plans, it is hard to implement because of: (i) the uniqueness of disaster incidents and randomness of its impacts; (ii) complexity of disaster debris removal operations, policy and regulations and (iii) interdependency of multiple infrastructure networks. Also, delayed debris removal operation affects following emergency response activities. Furthermore, uncontrolled debris removal activities can result in significant environmental and public health consequences. Therefore, there is a need for a systematic approach to optimizing post-disaster debris management systems. </div><div><br></div><div>This research is aimed to understand the complexity of debris management and associated emergent dynamics through the lens of an adaptive system-of-systems (SoS). To develop the adaptive decision support system, this research (a) identifies the interdependent infrastructure network within a community and its relative importance; (b) develops real-time GIS database to integrate the data associated with critical infrastructure and geographical characteristics in the community map; (c) designs and selects a TDMS network to analyze the required number, capacity and resources, based on engineering-technical, managerial, and social-political dynamics; (d) simulate the productivity of debris-management SoS based on the real-time GIS database to gain insight into the impact of the dynamical nature of a disaster-affected area; and (e) develop a visualized interactive GIS-based platform for debris management to communicate real-time debris clearance strategies and operations among different agencies and organizations.</div><div><br></div><div>To evaluate the proposed framework and decision support system, this research conducted a case study, debris removal operation in the city of Baton Rouge, after the 2016 Louisiana flood. The results demonstrated the influence of sub-systems such as TDMS locations and capacity, road network condition, available resources, existing regulations and policies, characteristics of community on the behavior of the entire disaster debris removal management as a whole. </div><div><br></div><div>The proposed decision support system for effective disaster debris management will be beneficial for emergency agencies and disaster-prone communities to evaluate and optimize their disaster debris management system. Also, the system can be systematically integrated with other emergency response systems to maximize the efficiency of the entire disaster responses during post-disaster situations. </div><div><br></div>

This study reviews the current knowledge and state of the practice for handling floating debris for dam safety. This report is a guidance to improve the understanding of risks of floating debris for dam safety and of countermeasures for risk reduction. The strengths and limitations of current approaches related to dam vulnerability assessment and handling strategies are discussed and recommendations are provided. Several countries experienced issues with floating debris which often led to severe damages to  dam spillways. High and extreme flood events could be responsible for similar incidents in Sweden which requires to systematically assess dam vulnerability to floating debris and examine suitable countermeasures. A vulnerability assessment involves investigating the potential for debris production, for debris transport to the dam facility and for blockage and drawdown at spillways. Various concepts for reducing the vulnerability of dam spillways to floating debris were presented in the technical literature. Countermeasures for floating debris management based on a river perspective approach involve controlling the debris yield produced in a catchment, the interception of floating debris in tributaries and reservoirs and measures taken at dam spillways to facilitate floating debris passage. Floating debris management often requires opting for a combination of suitable and cost-efficient measures rather than a single line of defense.
