Book Description
Casualties and damages from urban pluvial flooding are increasing. Triggered by short, localized, and intensive rainfall events, urban pluvial floods can occur anywhere, even in areas without a history of flooding. Urban pluvial floods have relatively small temporal and spatial scales. Although cumulative losses from urban pluvial floods are comparable, most flood risk management and mitigation strategies focus on fluvial and coastal flooding. Numerical-physical-hydrodynamic models are considered the best tool to represent the complex nature of urban pluvial floods; however, they are computationally expensive and time-consuming. These sophisticated models make large-scale analysis and operational forecasting prohibitive. Therefore, it is crucial to evaluate and benchmark the performance of other alternative methods. The findings of this cumulative thesis are represented in three research articles. The first study evaluates two topographic-based methods to map urban pluvial flooding, fill-spill-merge (FSM) and topographic wetness ...

Book Description
This open access book addresses the way in which urban and urbanizing regions profoundly impact and are impacted by climate change. The editors and authors show why cities must wage simultaneous battles to curb global climate change trends while adapting and transforming to address local climate impacts. This book addresses how cities develop anticipatory and long-range planning capacities for more resilient futures, earnest collaboration across disciplines, and radical reconfigurations of the power regimes that have institutionalized the disenfranchisement of minority groups. Although planning processes consider visions for the future, the editors highlight a more ambitious long-term positive visioning approach that accounts for unpredictability, system dynamics and equity in decision-making. This volume brings the science of urban transformation together with practices of professionals who govern and manage our social, ecological and technological systems to design processes by which cities may achieve resilient urban futures in the face of climate change.

Book Description
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).

Book Description
Flooding is the natural hazard with the greatest economic and social impact in the United States, and these impacts are becoming more severe over time. Catastrophic flooding from recent hurricanes, including Superstorm Sandy in New York (2012) and Hurricane Harvey in Houston (2017), caused billions of dollars in property damage, adversely affected millions of people, and damaged the economic well-being of major metropolitan areas. Flooding takes a heavy toll even in years without a named storm or event. Major freshwater flood events from 2004 to 2014 cost an average of $9 billion in direct damage and 71 lives annually. These figures do not include the cumulative costs of frequent, small floods, which can be similar to those of infrequent extreme floods. Framing the Challenge of Urban Flooding in the United States contributes to existing knowledge by examining real-world examples in specific metropolitan areas. This report identifies commonalities and variances among the case study metropolitan areas in terms of causes, adverse impacts, unexpected problems in recovery, or effective mitigation strategies, as well as key themes of urban flooding. It also relates, as appropriate, causes and actions of urban flooding to existing federal resources or policies.

Book Description
Accurate simulation of compound flooding is crucial for flood risk management. In coastal regions, both rainfall runoff and storm surge can contribute to flooding and are not mutually exclusive. It is thus necessary to develop a modeling framework for compound flooding that considers both mechanisms. While many hydrologic models have been developed to simulate the rainfall runoff processes, a lot of these methods are either computationally expensive, or incapable of simulating extreme weather events. Thus, they may not be suitable for coupled modeling of compound flooding. In this study, a data-driven hydrologic model based on deep recurrent neural network (RNN) is developed for rainfall runoff simulation at relatively low computational cost. To test the capability of the method, the model is used to infer the streamflow out of an urban watershed, Brays Bayou in Houston, Texas. And the model is validated with real world hydrologic data. Additionally, the proposed synced sequence to sequence RNN architecture is compared with the sequence input single output one that is widely-used in hydrologic modeling. Numerical experiments show that the proposed method provides more accurate predictions using relatively less computational resources than the sequence input single output architecture. Later, downstream water level input is integrated into the RNN model to enable the one-way coupling of rainfall runoff with storm surge. Numerical examples at two different locations demonstrate that the additional information leads to improved predictions. Finally, a two-way dynamic coupling framework is constructed for the RNN hydrologic model and an ocean circulation model, ADvanced CIRCulation. The framework is tested, verified, and validated for the Houston ship channel - Galveston bay estuarine system during Hurricane Harvey (2017). This dissertation is based on the following articles: High temporal resolution rainfall runoff modelling using Long-Short-Term-Memory (LSTM) networks by Wei Li, Amin Kiaghadi, Clint Dawson [1]; Exploring the best sequence LSTM model- ing architecture for flood prediction by Wei Li, Amin Kiaghadi, Clint Dawson [2]; and Simulating compound floods: dynamic coupling of deep learning and physics- based models by Wei Li, Gajanan Choudhary, Amin Kiaghadi, Clint Dawson.

Book Description
Pluvial flooding is defined as flooding that results from rainfall-generated overland flow, before the runoff enters any watercourse or sewer. It is usually associated with high intensity rainfall events (typically >30mm/h) but can also occur with lower intensity rainfall or melting snow where the ground is saturated, frozen, developed or otherwise has low permeability resulting in overland flow and ponding in depressions in the topography. Urban pluvial flooding arises from high intensity ‘extreme’ rainfall events. In such situations urban underground sewerage/drainage systems and surface watercourses may be completely overwhelmed. This volume deals with the many aspects involved with pluvial and coincidental flooding. It investigates causes and consequences. In order to reduce the impact of this type of flood, it presents various techniques to anticipate and forecast floods. Moreover, it presents way to reduce the impact and consequences, both short and long term. Case studies and instructions for training and education are included as well. The chapters were contributed by experts on the subject, that have been active in flood management and flood impact reduction in many countries. - presents advanced techniques for urban flood date collection, processing, modelling and forecasting - contains contributions on water quality, health impact, vulnerability and socio-economic impact - includes case studies and a part on education and training Table of Contents Introduction – Urban Flooding – A global issue; Types of flooding and their coincidence / interaction with pluvial flooding; Data needs, acquisition and data processing for urban flood modelling and management; Conventional Modelling of floods and interactions 5.
