Book Synopsis After the Flood by : Emma Jane Spett
Download or read book After the Flood written by Emma Jane Spett and published by . This book was released on 2021 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: In April of 2011, heavy rainfall paired with snow melt from the Green and Adirondack Mountains caused unprecedented flooding in the Lake Champlain Richelieu River (LCRR) basin. A study was subsequently convened by the International Joint Commission (IJC), and was tasked with identifying how flood forecasting, preparedness, and mitigation could be improved in order to reduce the impact of flooding in this transboundary watershed, and build the greater community's resilience to flooding. A component of this study includes an assessment of the social acceptability and political feasibility of potential flood mitigation measures, which was in part carried out through the development and administration of a survey that assessed how residents of the LCRR basin perceive risk and engage with criteria used to make decisions regarding flood mitigation.The objective of this research is to provide insight into how members of the public in the LCRR basin consider flood risk and flood mitigation, and how those perceptions impact the feasibility of various flood mitigation measures, and can point policymakers in directions that are socially acceptable. To set the stage for the applied nature of this study, this thesis begins with an introduction to the operationalization of flood management research. That is followed by a review of relevant literature, including theories related to resilience of social-ecological systems, disaster resilience, and natural hazard risk perception. The third chapter of this thesis offers a case study of the social, political, and economic implications of the spring 2011 floods in the LCRR basin. Two articles are then presented. The first article uses the results of a household risk perception survey (N=151) designed and administered in 2019 to primarily investigate how flood experience, adoption of flood preparedness measures, and opinions regarding flood mitigation measures impact perceptions of flood risk. Socioeconomic and geographic variables are also considered. Findings indicate that perceptions of flood risk are primarily based on prior flood experiences, rather than dependent of characteristics that make respondents more vulnerable to flooding. Additionally, there are disconnects between perceptions of flood risk and likelihood of adopting preparedness measures, and where respondents get information versus who they trust for that information. In the second article, the results of a multi-criteria decision analysis from the same household risk perception survey are investigated. Respondents engaged with nine decision criteria, provided by the study, through ranking and scoring exercises. Results were assessed through a process called Technique for Ordered Preference Similarity to the Ideal Solution (TOPSIS), where the ranks and scores were weighted and normalized. Respondents were broken into a variety of clusters, and their ranks were assessed in comparison with other clusters. Findings indicate that respondents primarily preferred criteria which indicated altruistic outcomes from flood mitigation measures, although later rankings indicated significant variation based on demographic characteristics, geographic location, and flood experiences. This thesis concludes with a summary, policy implications, and recommendations for future research. A further investigation into the value of flood early warning systems is provided, in addition to an agenda for exploring these concepts more deeply.
Book Synopsis Improving Flood Prediction Assimilating Uncertain Crowdsourced Data into Hydrologic and Hydraulic Models by : Maurizio Mazzoleni
Download or read book Improving Flood Prediction Assimilating Uncertain Crowdsourced Data into Hydrologic and Hydraulic Models written by Maurizio Mazzoleni and published by CRC Press. This book was released on 2017-03-16 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the continued technological advances have led to the spread of low-cost sensors and devices supporting crowdsourcing as a way to obtain observations of hydrological variables in a more distributed way than the classic static physical sensors. The main advantage of using these type of sensors is that they can be used not only by technicians but also by regular citizens. However, due to their relatively low reliability and varying accuracy in time and space, crowdsourced observations have not been widely integrated in hydrological and/or hydraulic models for flood forecasting applications. Instead, they have generally been used to validate model results against observations, in post-event analyses. This research aims to investigate the benefits of assimilating the crowdsourced observations, coming from a distributed network of heterogeneous physical and social (static and dynamic) sensors, within hydrological and hydraulic models, in order to improve flood forecasting. The results of this study demonstrate that crowdsourced observations can significantly improve flood prediction if properly integrated in hydrological and hydraulic models. This study provides technological support to citizen observatories of water, in which citizens not only can play an active role in information capturing, evaluation and communication, leading to improved model forecasts and better flood management.

Download or read book Flood Forecasting Using Machine Learning Methods written by Fi-John Chang and published by MDPI. This book was released on 2019-02-28 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, the degree and scale of flood hazards has been massively increasing as a result of the changing climate, and large-scale floods jeopardize lives and properties, causing great economic losses, in the inundation-prone areas of the world. Early flood warning systems are promising countermeasures against flood hazards and losses. A collaborative assessment according to multiple disciplines, comprising hydrology, remote sensing, and meteorology, of the magnitude and impacts of flood hazards on inundation areas significantly contributes to model the integrity and precision of flood forecasting. Methodologically oriented countermeasures against flood hazards may involve the forecasting of reservoir inflows, river flows, tropical cyclone tracks, and flooding at different lead times and/or scales. Analyses of impacts, risks, uncertainty, resilience, and scenarios coupled with policy-oriented suggestions will give information for flood hazard mitigation. Emerging advances in computing technologies coupled with big-data mining have boosted data-driven applications, among which Machine Learning technology, with its flexibility and scalability in pattern extraction, has modernized not only scientific thinking but also predictive applications. This book explores recent Machine Learning advances on flood forecast and management in a timely manner and presents interdisciplinary approaches to modelling the complexity of flood hazards-related issues, with contributions to integrative solutions from a local, regional or global perspective.
Book Synopsis Novel Approaches to Simulate Flood Inundation from Manholes and Watersheds by : Merhawi GebreEgziabher GebreMichael

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flood prediction and forecast for watershed and urban areas are critical for planning stormwater systems and assessing flood risks. While some hydrodynamic models can simulate flood inundation, most of these models are commercial and require large datasets and computational resources that limit their applications. This study developed two simplified and computationally efficient flood mapping models for delineating flood hazard zones using readily available datasets. The first model, flood inundation and recession model (FIRM), was developed using digital elevation maps to predict flooding associated with manhole overflow during and following flood events. The model was coupled with the 1D Storm Water Management Model (SWMM) to characterize the spatial extent and depth of manhole flooding and recession. I tested the coupled model for two manhole flooding events in Edmonds, WA. The results show a reasonable match between the observed and modeled flood areas, highlighting the importance of considering manholes in urban flood simulations. The second model delineates flood extent and depth at the catchment level using the NRCS curve number method for runoff productions at grids and a computationally efficient flood routing method. The gridded runoff estimated by the NRCS method is used as input to the flood inundation model that iteratively routes the runoff based on elevation variation, flood connectivity, and the assumption of level-water surface propagation. I tested the model using the recent flood event in the upper Umatilla River watershed. Several statistical criteria were used to evaluate the model's performance by comparing the simulation results with the reconstructed flood boundaries delineated using photos and drone videos during the flood event. The results demonstrate the model's ability to simulate and predict flood extent and depth accurately within the watershed. Due to its computational efficiency and its uses of readily available datasets, the model is suitable for near real-time flood forecast and early warning decisions. The model is also useful for determining the flood level associated with design storms obtained from the intensity-duration-frequency (IDF) curves, further improving stormwater system designs.
Book Synopsis The Assessment, Improvement, and Application of the GeoFlood Flood Inundation Mapping Framework by : Alec Carruthers
Download or read book The Assessment, Improvement, and Application of the GeoFlood Flood Inundation Mapping Framework written by Alec Carruthers and published by . This book was released on 2020 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: GeoFlood is a flood inundation mapping package that utilizes a geodesic, cost minimization algorithm to extract channel networks from high resolution terrain data along with National Water Model forecasts and a Height Above Nearest Drainage approach to create near real time flood inundation maps. Earlier work has applied the GeoFlood framework at the scale of a single Hydrologic Unit Code 12 watershed, but this work extended the application to seven counties across the state of Texas. One meter resolution lidar digital elevation models were generated for each county and segmented by watershed, resulting in approximately 400 gigabytes of input data. Two cost functions were found to improve the channel network extraction capabilities. The unique aspect of the first cost function was the inclusion of a cost threshold, which served to increase the penalty for pixels that had a cost above a given limit, thereby restricting the extracted channel to only the minimum cost path and preventing shortcuts. A second cost function, featuring a binary representation of the National Hydrography Data high resolution flowlines, was used to improve the performance of the threshold based cost function in the presence of artificial features or within low relief topography. Four variations of a channel bed slope calculation were tested, two that were end point based and two that utilized a linear regression. The end point based methods were shown to have synthetic rating curves with a smaller percent error and variance across the first three meters of stage height, as well as less area separation from the corresponding United States Geological Survey synthetic rating curves than the regression based methods. Identification of the reaches in which the slope calculation method was most significant was conducted by analyzing the variance and standard deviation across the four computed slopes. Artificial and canal reaches at a low level (1 - 2) and high stream order (5 - 7) were found to have the most variance across their computed slopes. A reach being hydro-flattened was determined to most likely not be the sole limiting factor when it comes to the accuracy of GeoFlood derived products. An approximately equal number of low and high error synthetic rating curves were produced from hydro-flattened reaches. While improvement to the model can always be made, the application of GeoFlood across seven counties in Texas, using high resolution terrain data, was a step forward in regard to showing that GeoFlood can be applied to larger study areas than just a single watershed, including the potential for statewide and or national implementation

This book was released on 2013 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: To address the uncertainties of river flood forecasting and to contribute a new visualization for flood mapping, this study outlines a methodology for creating dynamic probabilistic flood inundation maps for a floodplain which currently lacks dynamic flood maps of any kind. To create these maps, a hydrologic model is specially constructed using HEC-RAS for a segment of the Tonawanda Creek in western New York. The model is constructed using pre-existing, publically available data, including a LiDAR digital elevation model, real-time discharge observations from a USGS-maintained gauge on the creek, and other characteristics of the creek's bathymetry derived from previous flood insurance studies. The model is then used to create inundation rasters based on selected initial discharges. To determine probabilities, predicted peak discharges for the Tonawanda Creek are first collected from the Meteorological Model-based Ensemble Forecast System (MMEFS), which generates predictions of various hydrometeorological parameters in real-time, and are used to create a suite of inundation rasters, one for each individual peak discharge prediction. These inundation rasters are then overlaid and the probabilities are calculated by grid cell based on how many inundations overlap. The resulting map depicts the range of flooding extent probabilities based on the real-time forecast. An alternative probabilistic map is also devised to depict the depth of flooding given a flood event's probability. The 10th, 50th, and 90th percentiles are calculated for the forecast ensemble's peak discharge predictions. These percentiles correspond to benchmarks of flooding likelihood, such that the 10th percentile indicates a 90% likely flood event, 50th percentile a 50% event, and 90th percentile a 10% event. Once completed, the maps are qualitatively evaluated for potential applications in predicting flood events and mitigating flood-induced damages.

Download or read book Stochastic Flood Forecasting System written by Renata J. Romanowicz and published by Springer. This book was released on 2015-06-29 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the novel formulation and development of a Stochastic Flood Forecasting System, using the Middle River Vistula basin in Poland as a case study. The system has a modular structure, including models describing the rainfall-runoff and snow-melt processes for tributary catchments and the transformation of a flood wave within the reach. The sensitivity and uncertainty analysis of the elements of the study system are performed at both the calibration and verification stages. The spatial and temporal variability of catchment land use and river flow regime based on analytical studies and measurements is presented. A lumped parameter approximation to the distributed modelling of river flow is developed for the purpose of flow forecasting. Control System based emulators (Hammerstein-Wiener models) are applied to on-line data assimilation. Medium-range probabilistic weather forecasts (ECMWF) and on-line observations of temperature, precipitation and water levels are used to prolong the forecast lead time. The potential end-users will also benefit from a description of social vulnerability to natural hazards in the study area.
