Urban Flood Mitigation Strategies Using Geo Spatial Tools

The disastrous effects of floods in urban areas of various Indian cities have been increasing in severity and extent over the past decade. This book explores flood disasters, their impact in world and Indian contexts, assessing vulnerability and risks involved, and systematic use of (GIS)-enabled platforms to map mitigation measures sustainably, with special reference to the metropolitan flood mitigation endeavors. This book balances the theoretical with empirical approaches to form a unique standpoint on the various challenges and possible solutions to urban flooding in India. Through a study of major urban flood incidents, this book analyzes the factors which contribute to the rising risk of flooding with increasing urbanization, population dynamics, growth, and urban sprawl, with particular focus on the cities of Chennai, Mumbai, and Hyderabad in India. It also examines disaster governance on urban floods and legislative prospects of flood disasters through discussions on standing acts, United Nations (UN) directives, and internationally adopted practices and actions, which are applicable in the Indian context. An interdisciplinary study, this book brings together tools and research from various disciplines including geography, urban and regional planning, and GIS. It will be an invaluable resource for researchers, scholars, engineers, students, planners, academicians, and professionals of cross-disciplines to help them resolve the problem of urban flooding. It will also be of interest to the general reader seeking to learn more about disasters, urban flooding, engineering, and GIS.

Flooding is one of the most devastating natural hazards in the world. Available records suggest that both flood frequency and severity are on the rise and this is likely to worsen in the context of climate change. As population, infrastructure and poverty grow rapidly in developing countries, particularly in urban agglomerations of 10 million people or more, floods could cause widespread devastation, economic damage and loss of life. Assessment of vulnerability and risk from naturally occurring phenomena is therefore imperative in order to achieve urban sustainability. This book uses geospatial techniques to evaluate hazards, risk and vulnerability at a metropolitan scale in a data-scarce country. An empirical study was performed using remote sensing, GIS and census data. This research offers a new approach to mapping population, infrastructures and communities at risk which can greatly contribute to the deeper understanding of flood disasters in a rapidly expanding megacity. Examples shown in this book are from Dhaka Megacity, however, the techniques and methods can easily be implemented in medium to large cities of similar characteristics. The book is essential reading for hazard researchers, geospatial scientists, disaster management professionals, geographers, urban planners, and social scientists. Ashraf M. Dewan is currently a Lecturer in the Department of Spatial Sciences at Curtin University, Western Australia (on leave from his substantive position as Associate Professor in the Geography & Environment Department at the University of Dhaka, Bangladesh).

Over the last decades the world has witnessed a growing number of floods in urban areas. Climate change and rapid urbanization will exacerbate this trend. Flooding incidents in urbanized catchments and low-lying areas, such as polders, can lead to great public concern and anxiety, and their economical impact is severe. Apart from well-known flood prevention strategies, new approaches to the accommodation of floods are needed to create robust and sustainable solutions that enable us to cope with the ever-increasing urban pressure on flood-prone areas and the uncertainties created by climate change. Urban Flood Management comprises a multidisciplinary survey of recent developments in this field. Subjects like spatial and urban planning, flood insurance, flood resilience, flood proofing techniques, risk perception and preparedness and flood forecasting are treated by authorities from Brazil, India, the USA and Europe. Urban Flood Management will provide anyone active in the fields of water, risk and urban management with the latest information and insights that were obtained with a global and multidisciplinary approach.

This book is the second in a series that examines how geographic information te- nologies (GIT) are being implemented to improve our understanding of a variety of hazard and disaster situations. The main types of technologies covered under the umbrella of GIT, as used in this volume, are geographic information systems, remote sensing (not including ground-penetrating or underwater systems), and global po- tioning systems. Our focus is on urban areas, broadly de ned in order to encompass rapidly growing and densely populated areas that may not be considered “urban” in the conventional sense. The material presented here is also unabashedly applied – our goal is to provide GIT tools to those seeking more ef cient ways to respond to, recover from, mitigate, prevent, and/or model hazard and disaster events in urban settings. Therefore, this book was created not only with our colleagues in the academic world in mind, but also for hazards professionals and practitioners. We also believe graduate students will nd the material presented here of interest, as may upper division undergraduate students.

One of the effects of global climate change is the increasing variability of extreme flood events and cyclones. Current measures to mitigate flood impacts, particularly in the urban environment, are based on previously-planned flood risk intervals and no longer provide sufficient protection. Being prepared for unexpected changes and extreme flood events asks for a paradigm shift in current strategies to avoid and manage flood disasters. In order to stem the increasing impact of urban floods, a major rethink of current planning and flood management policies and practice is required, taking into account different spatial and temporal scales. This book addresses a broad spectrum of relevant issues in the emerging field of urban flood management. It may act as a stimulus for further research and development in urban flood management while informing and engaging stakeholders in the promotion of integrated and cooperative approaches in water management. An interdisciplinary approach which will be of interest to all those who are active in water, risk and urban management.

This book examines the application of geotechniques to address a wide range of issues facing urban water resources. Growing populations leading to urbanization and related development have lead to problems associated with water quality, storm water management, flood control, environmental health, and related ecosystem impacts. Major cities and other urban areas are facing challenges in addressing the implications of impacts to water resources. Recent innovations in geotechnologies, including Geographic Information Science (GIS), remote sensing, and other spatial tools and techniques, provide great opportunities and potential to assist in dealing with these problems. This volume provides a series of case studies that examine the application of new methods and approaches in a range of geotechnologies as utilized to better understand and resolve urban water resource concerns in communities throughout the world. Computer based mapping, spatial analysis, satellite imagery, decision support systems, web based applications, aerial photography, and other methods are highlighted by their development and application. The research presented in this volume will provide for an excellent source of knowledge and learning to assist professionals, experts, and students with a better understanding of how the use of geotechnologies can be used to assist urban communities to address water resource challenges.
