A simulation environment is being developed for the prediction and analysis of the inundation consequences for infrastructure systems from extreme flood events. This decision support architecture includes a GIS-based environment for model input development, simulation integration tools for meteorological, hydrologic, and infrastructure system models and damage assessment tools for infrastructure systems. The GIS-based environment processes digital elevation models (30-m from the USGS), land use/cover (30-m NLCD), stream networks from the National Hydrography Dataset (NHD) and soils data from the NRCS (STATSGO) to create stream network, subbasins, and cross-section shapefiles for drainage basins selected for analysis. Rainfall predictions are made by a numerical weather model and ingested in gridded format into the simulation environment. Runoff hydrographs are estimated using Green-Ampt infiltration excess runoff prediction and a 1D diffusive wave overland flow routing approach. The hydrographs are fed into the stream network and integrated in a dynamic wave routing module using the EPA's Storm Water Management Model (SWMM) to predict flood depth. The flood depths are then transformed into inundation maps and exported for damage assessment. Hydrologic/hydraulic results are presented for Tropical Storm Allison.

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.

Flood zones with 1% and 0.02% of annual flooding chance are projected in the Federal Emergency Management Agency’s (FEMA) digital flood insurance rate maps (DFIRMs) and are suited for identifying flood risk at the largest impacts. However, less severe floods, which are not mapped in DFIRMs, still cause significant damage and occur on a more frequent basis. This article employs an easy-to-setup GIS-based solution for rapid inundation mapping of small flood events. The linear interpolation technique (LITE Flood) is developed to rescale the hydraulic behavior inherent with a larger flood event without performing additional hydraulic simulations. The approach is evaluated by comparing the results to the corresponding storm scenarios simulated in the HEC-RAS, a standard river hydraulics simulator. The case study is a portion of the Wolf River and its two main tributaries in Shelby County that is located in the southwest corner of Tennessee, USA, where stream channelization mitigated large flood events but has caused frequent flooding from less severe storms. Results indicate that LITE Flood can be used to delineate more frequent storm events, thereby aiding local community emergency response agencies who often do not have the expertise to perform more sophisticated hydraulic modeling but do have a GIS capacity..

This research is not intended to specifically represent the inundation risk due to a probabilistic 100-year SS and sea level rise for any specific building or land parcel. However, this is a good indication for what may occur. The methodology could also be used as a supplementary for forecasting economic analysis and future land use planning or county resilience planning.

If Hurricane Ike had made landfall just fifty miles down the Texas coast, the devastation and death caused by what was already one of the most destructive hurricanes in US history would have quadrupled. Ike made everyone realize just how exposed and vulnerable the Houston-Galveston area is in the face of a major storm. What is done to address this vulnerability will shape the economic, social, and environmental landscape of the region for decades to come. In Lessons from Hurricane Ike, Philip Bedient and the research team at the Severe Storm Prediction, Education, and Evacuation from Disasters (SSPEED) Center at Rice University provide an overview of some of the research being done in the Houston-Galveston region in the aftermath of Hurricane Ike. The center was formed shortly after Hurricanes Katrina and Rita in 2005. Its research examines everything from surge and inland flooding to bridge infrastructure. Lessons from Hurricane Ike gathers the work of some of the premier researchers in the fields of hurricane prediction and impact, summarizing it in accessible language accompanied by abundant illustrations—not just graphs and charts, but dramatic photos and informative maps. Orienting readers to the history and basic meteorology of severe storms along the coast, the book then revisits the impact of Hurricane Ike and discusses what scientists and engineers are studying as they look at flooding, storm surges, communications, emergency response, evacuation planning, transportation issues, coastal resiliency, and the future sustainability of the nation’s fourth largest metropolitan area.

Applications of remote sensing technology for monitoring and predicting water-related hazards Water-related hazards such as floods and droughts have serious impacts on society. Their incidence has increased in recent decades, a trend set to continue with ongoing climate change. Adaptation and mitigation measures require accurate detection, monitoring, and forecasting, much of which comes from remote sensing technologies. Remote Sensing of Water-Related Hazards takes an interdisciplinary approach, presenting recent advances in the available data, sensors, models, and indicators developed for monitoring and prediction. Volume highlights include: Progress in remote sensing of precipitation, storms, and tornados Different techniques for flood mapping, forecasting, and early warning Integrated approach for predicting flood and landslide cascading hazards Satellite monitoring of water cycle variation, water scarcity, and drought conditions Multi-indicator and multi-sensor approaches for quantifying drought impacts The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

The report contains an adaptation of a unique storm-surge forecasting technique developed by Dr. C.P. Jelesnianski. This technique results in a computed storm surge profile at the inner boundary of an artificial standard basin seaward of the coast. The profile is derived from nomograms based upon a standard storm passing over a standard basin. Thumb rules and guidelines are presented in the publication for subjectively modifying the computer storm surge height as it moves shoreward of the artificial basin boundary, to fit the natural conditions of a particular coastline. Major advantages of this system are its applicability to almost any locale, its adaptability to data normally available to the field forecaster and the speed with which the forecast may be modified to remain current with natural fluctuations of the storm.
