Processos físicos e modelos computacionais em engenharia costeira
Após identificação de diversas situações de grande vulnerabilidade e risco presentes num trecho da costa portuguesa, continua esta obra com uma abordagem de aspetos relativos à hidrodinâmica e a desenvolvimentos numéricos básicos no domínio da engenharia costeira. Seguem-se descrições dos processos de geração das ondas no mar e das transformações que ocorrem numa onda ao propagar-se desde o largo até à costa. São apresentadas as diferentes teorias da onda e é abordada com mais detalhe a teoria geral da onda em condições de água pouco profunda. São abordados os processos físicos envolvidos e as metodologias comumente usadas na modelação da morfodinâmica costeira, i...
Coastal and Marine Environments
This book systematizes the concepts of contemporary coastal zone management and suggests possible structural and non-structural management tools for decision-making processes. Some successful adaptation measures and case studies on oceanic processes and coastal protection are discussed. High-frequency communications in coastal and marine environments are also addressed.All chapters contribute relevant information and useful content to scientists and other readers interested or concerned about the lack of adequate management actions and the installation of appropriate protections or their ineffectiveness in containing coastal vulnerabilities and risks.
River Basin Management
This book addresses recent advances in the field of river systems. Chapters cover a wide range of topics including artificialization of rivers and banks, technical aspects of flood and sediment dynamics, physical processes and institutional vulnerabilities, watershed management and collaborative governance, water quality analysis and protection measures, acquisition and measurement of data, statistical and econometric procedures, adaptation and restoration measures, rehabilitation and sustainability of riparian ecosystems, and strategies to improve the ecological functions of riparian areas. All chapters contribute relevant information and useful content for scientists and other readers interested or concerned about the lack of adequate management actions and implementation of appropriate measures and protections, or their ineffectiveness in containing vulnerabilities and ecological sustainability of river systems.
Natural Hazards
This book addresses different aspects of natural hazards and vulnerabilities, with a focus on prevention and protection. It consists of nine chapters, five on flood events addressing vulnerabilities, risk assessments, impacts, sensitivity analyses, and mitigation measures, two on climate change and reconstruction of natural hazard events such as avalanches and rockslides, and two on tsunamis and volcanoes. All chapters provide relevant information and useful elements for readers interested and concerned about the lack of action or its ineffectiveness in containing the vulnerabilities and risks of possible natural hazards worldwide.
Advances in Water Quality Control
World water resources seem to be abundant; however, only 0.7% of this total amount is usable water. And owing to their nonuniform distribution, some countries have abundant water resources, whereas some others suffer from inadequate water, and even face severe water scarcity problems. Moreover, serious water pollution problems make 1/5 of the world’s population (approximately 1.1 billion people) under the risk of water-related diseases. In order to give a guideline to maintain the required quality of water according to the intended use, a group of international experts have come together to write this book. Authors target to pass recent available knowledge and information to the readers, who will vary from academicians, professional engineers and scientists, to undergraduate and graduate engineering students concerned with water quality problems all over the world. This book covers the main fields of Wastewater Treatment with 12 chapters, and uses knowledges in economic, information technologies, biology, etc. to make comprehensive analyses and applications.
New Perspectives in Fluid Dynamics
This book contains five chapters detailing significant advances in and applications of new turbulence theory and fluid dynamics modeling with a focus on wave propagation from arbitrary depths to shallow waters, computational modeling for predicting optical distortions through hypersonic flow fields, wind strokes over highway bridges, optimal crop production in a greenhouse, and technological appliance and performance concerns in wheelchair racing. We hope this book to be a useful resource to scientists and engineers who are interested in the fundamentals and applications of fluid dynamics.
Advanced Fluid Dynamics
This book provides a broad range of topics on fluid dynamics for advanced scientists and professional researchers. The text helps readers develop their own skills to analyze fluid dynamics phenomena encountered in professional engineering by reviewing diverse informative chapters herein.
Modelação em hidráulica fluvial e ambiente
Abordam-se nesta obra aspectos essenciais relativos às relações de semelhança em modelação física e confrontam-se as modelações física e numérica numa perspectiva de inter-dependência e complementaridade. Apresentam-se os principais modelos matemáticos para estudos de hidrodinâmica em meios fluviais e discutem-se várias técnicas numéricas de resolução das equações básicas. É dada grande ênfase ao estudo das solicitações hidrodinâmicas que podem conduzir à ruptura de uma barragem e, em consequência da ruptura, aos mecanismos de geração e propagação da onda de cheia resultante. Abordam-se conceitos básicos sobre os processos de erosão, transporte e deposiçã...
Advances in Spatio-Temporal Analysis
Developments in Geographic Information Technology have raised the expectations of users. A static map is no longer enough; there is now demand for a dynamic representation. Time is of great importance when operating on real world geographical phenomena, especially when these are dynamic. Researchers in the field of Temporal Geographical Information Systems (TGIS) have been developing methods of incorporating time into geographical information systems. Spatio-temporal analysis embodies spatial modelling, spatio-temporal modelling and spatial reasoning and data mining. Advances in Spatio-Temporal Analysis contributes to the field of spatio-temporal analysis, presenting innovative ideas and examples that reflect current progress and achievements.
Thriving
Between 1970 and 2021, the number of people living in cities increased from 1.19 billion to 4.46 billion, while the Earth’s surface temperature climbed by 1.19 degrees Celsius above its preindustrial levels. Because of the prosperity they helped generate, cities have been a major cause of this climate change. However, it is also in cities that many of the solutions to the climate crisis—in terms of both adaptation and mitigation—will be found, not least because by 2050, almost 70 percent of the world’s population will call cities home. As such, cities are the key to arguably the greatest public policy challenge of our times. To take stock of how green, how resilient, and how inclusiv...
