Book excerpt: This study also showed that at the end of the century, hurricanes may produce larger surge magnitudes in concentrated areas as opposed to surges that are lower in magnitude and widespread. One notable finding of this study is that there is no single storm property that dictates the magnitude of surge inundation. Even when these properties are considered together, the results are still difficult to anticipate without explicit numerical simulation. Due to dynamic hurricane properties, storm surge risk communication has been challenging. Despite communication changes from the National Hurricane Center, we have found that there is a lingering association between the Saffir-Simpson Hurricane Wind Scale (SSHWS) and storm surge risk by the general public. However, findings suggest that although improving communication can indeed improve risk perception, it only addresses one component of a multidisciplinary system that defines storm surge risk. To be truly effective, resilience efforts will require multidisciplinary approaches.

This book was released on 1980 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Federal services that minimize loss of life and property due to tropical hurricanes include forecasts and flood warnings. Because of the different concerns of these agencies their models have evolved in different ways and are applied with different input data, and apparent disparities have appeared. Evaluation was accomplished by having each modeling group separately exercise its models for selected past events and by comparing the model outputs with each other and with observed water elevations. Open-coast storm surge models were evaluated, then inland flooding models were evaluated using as input one of the open-coast model results. Each model tested included features that offered important advantages. Further, the models were continually evolving to include improved descriptions of the land and waters and of storms. No one model's predictions consistently gave better comparisons with observed data, however; and it is unlikely that one will be clearly better than the others for Corps purposes.

Available in PDF, EPUB and Kindle. Book excerpt: Hurricanes are incredibly devastating events, constituting seven of the ten most costly U.S. natural disasters since 1980. The development of real-time forecasting models that accurately capture a storm's dynamics play an essential role in informing local officials' emergency management decisions. ADCIRC is one such model that is operationally active in the National Oceanic and Atmospheric Administration's Hurricane Surge On-Demand Forecast System. However, ADCIRC faces several limitations. It struggles solving highly advective flows and is not locally mass conservative. These aspects limit applicable flow regimes and can cause unphysical behavior. One proposed alternative which addresses these limitations is the discontinuous Galerkin (DG) finite element method. However, the DG method's high computational cost makes it unsuitable for real-time forecasting and has limited adoption among coastal engineers. Simultaneously, efforts to build an exascale machine and the resulting power constrained computing architectures have led to massive increases in the concurrency applications are expected to manage. These architectural shifts have in turn caused some groups to turn away from the traditional flat MPI or MPI+OpenMP programming models to more functional task-based programming models, designed specifically to be performant on these next generation architectures. The aim of this thesis is to utilize these new task-based programming models to accelerate DG simulations for coastal applications. We explore two strategies for accelerating the DG method for storm surge simulation. The first strategy addresses load imbalance caused by coastal flooding. During the simulation of hurricane storm surge, cells are classified as either wet or dry. Dry cells can trivially update, while wet cells require full evaluation of the physics. As the storm makes landfall and causes flooding, this generates a load imbalance. We present two load balancing strategies---an asynchronous diffusion-based approach and semi-static approach---to optimize compute resource utilization. These load balancing strategies are analyzed using a discrete-event simulation that models the task-based storm surge simulation. We find speed-ups of up to 56% over the currently used mesh partitioning and up to 97% of the theoretical speed-up. The second strategy focuses on a first order adaptive local timestepping scheme for nonlinear conservation laws. For problems such as hurricane storm surge, the global CFL timestepping constraint is overly stringent for the majority of cells. We present a timestepping scheme that allows cells to stably advance based on local stability constraints. Since allowable timestep sizes depend on the state of the solution, care must be taken not to incur causality errors. The algorithm is accompanied with a proof of formal correctness that ensures that with a sufficiently small minimum timestep, the solution exhibits desired characteristics such as a maximum principle and total variation stability. The algorithm is parallelized using a speculative discrete event simulator. Performance results show that the implementation recovers 59%-77% of the optimal speed-up

Available in PDF, EPUB and Kindle. Book excerpt: Storm surges represent a major hazard for many coastal regions worldwide. The 1953 and 1962 catastrophes are well remembered in Europe, and recent incidents in Bangladesh and Myanmar caused over 100,000 casualties. Developing innovative responses and overcoming the frequently fragmented discussion about this global phenomenon and its regional implications call for improved knowledge of present risks and future conditions based on sound interdisciplinary approaches. This selection of articles presents multiple scientific and management oriented perspectives on current and future storm surges, covering the fields of observing, modelling and forecasting, risk and vulnerability analysis, planning and innovative coastal protection concepts. It originates from the international ‘2010 Storm Surges Congress - Risk and Management of Current and Future Storm Surges,’ initiated and organized by the Institute of Coastal Research, Helmholtz-Zentrum Geesthacht (formerly the GKSS-Research Centre) in collaboration with the KlimaCampus (CliSAP) of the University of Hamburg, Germany. The Land-Ocean Interactions in the Coastal Zone (LOICZ) co-sponsored the event and its international project office (IPO) provided the necessary organizational support. The congress was generously supported by international and national partners. Some highlights: Remote sensing surveillance and mapping of storm surge extent based on NASA MODIS sensors may ultimately provide new global insights into the vulnerability of deltas where human pressures outbalance natural land-ocean forcing. Up-scaling hazard lines and risk mapping from local to full continental scale is the ambition in India. From an insurance risk perspective, its societal perception and economic issues determine societal response options. In urban contexts flood risk is anticipated as a combination of climate change-induced sea level rise and socio-economic drivers. A cost-benefit analysis of flood defence in London underlines the fact that future investment will be highly beneficial; thoughtful planning rather than rushing to new engineering solutions is preferable. Several modelling case studies and approaches are presented, covering the effects of individual storms, the development of analytical models that can help us to understand relevant processes and mechanisms, and sensitivity studies that test the impact and relevance of various physical processes for storm surge generation and evolution. Hydrodynamic models applied to different emission scenarios suggest that the threat of extreme storm surges in the North Sea may increase but strong decadal fluctuations and internal variability need to be considered. A Korean study suggests that future global warming may not always lead to an increase in the number of intense cyclones or the magnitude of associated storm surges. Past and recent storm surges arising at the dune coast of France call for improved assessment and management of a growing flood risk in future sea-level rise projections. In the same context rather than deterministic approaches, considering the uncertainties that influence extreme water levels can significantly improve the design levels of coastal structures and flood defences. The innovative Dutch “Building with Nature” concept employs natural processes for coastal flood protection. Previously published in Natural Hazards, Volume 66, No. 3, 2013
Download or read book Modeling Reconstruction and Trend Analysis of Global Storm Surges Using a Data driven Approach written by Michael Getachew Tadesse and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Storm surge is the deadliest component of extreme sea levels with one of the highest global death tolls per event. Tide gauges are the primary sources for historical sea-level measurements from which storm surge data is extracted. However, tide gauges are unevenly distributed across the globe, and most records are short in length and have gaps; this creates a challenge to assess long-term trends and perform robust extreme value analysis. This dissertation introduces a data-driven storm surge modeling framework that trains statistical and machine learning models with atmospheric and oceanographic variables. Data-driven models (DDMs) are trained and validated for more than 800 tide gauges globally using datasets that are obtained from tide gauges, satellites, and atmospheric reanalyses. By forcing DDMs with five atmospheric reanalyses, a database of global daily maximum storm surge reconstructions (GSSR, http://gssr.info) is provided for 882 tide gauges covering the 1836-2019 period. The reconstruction datasets provide an opportunity to perform long-term trend analysis and robust extreme value analysis. However, some atmospheric reanalyses have inhomogeneities that translate to surge reconstructions, introducing spurious trends not reflected in observed surges. A Bayesian change point detection method has been applied to identify and remove spurious trends from GSSR surge reconstructions. It is shown in this dissertation, that after the change point analysis, GSSR provides several decades of additional reconstructed surge data in addition to what is already available from sea-level measurements. Utilizing the post-processed surge reconstructions, a long-term trend analysis of storm surge climate has been carried out globally, particularly with respect to the magnitude and frequency of storm surges. Trends are also separately computed for the satellite-era where all five GSSR reconstructions and observed surges overlap. It is shown that the use of ensemble surge reconstructions is advisable, if possible, rather than using a single reconstruction to account for uncertainties stemming from atmospheric reanalyses.
