Book excerpt: Digital flood-inundation maps for selected reaches of South Fork Licking River, Raccoon Creek, North Fork Licking River, and the Licking River in Licking County, Ohio, were created by the U.S. Geological Survey (USGS), in cooperation with the Ohio Department of Transportation; U.S. Department of Transportation, Federal Highway Administration; Muskingum Watershed Conservancy District; U.S. Department of Agriculture, Natural Resources Conservation Service; and the City of Newark and Village of Granville, Ohio. The inundation maps depict estimates of the areal extent of flooding corresponding to water levels (stages) at the following USGS streamgages: South Fork Licking River at Heath, Ohio (03145173); Raccoon Creek below Wilson Street at Newark, Ohio (03145534); North Fork Licking River at East Main Street at Newark, Ohio (03146402); and Licking River near Newark, Ohio (03146500). The maps were provided to the National Weather Service (NWS) for incorporation into a Web-based flood-warning system that can be used in conjunction with NWS flood-forecast data to show areas of predicted flood inundation associated with forecasted flood-peak stages. As part of the flood-warning streamflow network, the USGS re-installed one streamgage on North Fork Licking River, and added three new streamgages, one each on North Fork Licking River, South Fork Licking River, and Raccoon Creek. Additionally, the USGS upgraded a lake-level gage on Buckeye Lake. Data from the streamgages and lake-level gage can be used by emergency-management personnel, in conjunction with the flood-inundation maps, to help determine a course of action when flooding is imminent. Flood profiles for selected reaches were prepared by calibrating steady-state step-backwater models to selected, established streamgage rating curves. The step-backwater models then were used to determine water-surface-elevation profiles for up to 10 flood stages at a streamgage with corresponding streamflows ranging from approximately the 50 to 0.2-percent chance annual-exceedance probabilities for each of the 4 streamgages that correspond to the flood-inundation maps. The computed flood profiles were used in combination with digital elevation data to delineate flood-inundation areas. Maps of Licking County showing flood-inundation areas overlain on digital orthophotographs are presented for the selected floods. The USGS also developed an unsteady-flow model for a reach of South Fork Licking River for use by the NWS to enhance their ability to provide advanced flood warning in the region north of Buckeye Lake, Ohio. The unsteady-flow model was calibrated based on data from four flooding events that occurred from June 2008 to December 2011. Model calibration was approximate due to the fact that there were unmeasured inflows to the river that were not able to be considered during the calibration. Information on unmeasured inflow derived from NWS hydrologic models and additional flood-event data could enable the NWS to further refine the unsteady-flow model.

This book was released on 2016 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flood warning system can be effectively used to reduce the potential property damages and loss of lives. Therefore, a reliable flood warning system is required for the evacuation of people from probable inundation area in sufficient lead time. Hence, this study was commenced to predict the travel time and generate inundation maps along the Grand River, Ohio for various flood stages. A widely accepted hydraulic tool, Hydraulic Engineering Center River Analysis System (HEC-RAS), was used to perform the hydraulic simulation. HEC-GeoRAS, an ArcGIS extension tool, was used to prepare geospatial data and generate flood inundation maps for various flood stages. A topographic survey was conducted to obtain the accurate elevation of river channels. The hydraulic simulations were carried out using six different elevation datasets and various ranges of Manning's roughness to quantify the uncertainties in travel time and inundation area prediction due to the resolutions of the elevation datasets and Manning's roughness. The study showed that the coarse elevation dataset, which was 30m Digital Elevation Model (DEM) without integration of survey data, provided higher travel time and inundation area. It over predicted (11.03%-15.01%) in travel time and inundation area (32.56%-44.52%) for various return period floods when compared with the results of Light Detection and Ranging (LiDAR) integrated with survey data. Moreover, Manning's roughness was found to be more sensitive in channel sections than that of floodplains. The decrease in travel time and inundation area was observed with the decrease in Manning's roughness. The highest decrement of 21.38% and 8.97% in travel time and inundation area was observed when roughness value was decreased in channel sections, while the decrement in travel time and inundation area was 3.45% and 1.49% when roughness value was decreased in floodplains. The difference in predicted travel time and inundation area, while using LiDAR integrated with survey data, was not considerably different from 10m DEM integrated with survey data. However, LiDAR with survey data predicted conservative travel time which would be safe to consider for the evacuation planning from probable inundation areas. Therefore, LiDAR integrated with survey data was used for the calculation of travel time and generation of flood inundation maps for 12 different selected flood stages. The estimated travel time can be used for the evacuation of the people. Similarly, the rating curve and the flood inundation maps can be used to issue flood warning. More than 100 houses, many roads, bridges and parks along the Grand River are susceptible to 500 year return period flood. Therefore, it is suggested to install the siren system in various locations of the river. In addition, winter flooding due to ice jams is one of the major problems as it has caused severe damages along the Grand River and nearby bridge structures frequently. Therefore, the effects of ice cover and ice jams on the river level near bridges were investigated. The increase in river stage and inundation area was observed, when ice cover and ice jam was considered in the simulation. The average increase in river stage was approximately 2 ft for maximum winter discharge. Likewise, the increase in inundation area varied from 24% to 52% for various winter flows resulting in the highest increment for the lowest winter discharge. In addition, the increase in river stage was noticed at the upstream section of bridges during winter when the model was simulated considering bridges. The effects of resolution of elevation datasets and ice jam/ice cover in flood travel time and inundations maps would be valuable assets for decision makers and planners for flood management and rescue operation in future.

This book was released on 2011 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This project examines the flooding dynamics of the Muskingum River near the city of Zanesville, Ohio. Simulating various peak flood events using a hydrodynamic model will provide Muskingum County engineers with valuable information regarding inundated areas, extent, and effect on local communities for different flood events. The impact of various Muskingum River flood events, including the 100 year flood, on the urban environment in Zanesville, Ohio is studied. The project provides a useful hydraulic modeling framework that produces urban flooding maps for the city of Zanesville. These flood maps show how water surface elevations and water depths vary spatially and temporally, and provide a more detailed picture of how flood waves move in urban environments. A hydrodynamic model called LISFLOOD-FP is used to simulate river flow and flooding. LISFLOOD-FP is a finite-difference flood inundation model that can accurately model 1D or 2D channel flow along with 2D floodplain flow. Modeling efforts demonstrate that better knowledge of discharge on the Muskingum River provides a valuable insight into how floods travel through the floodplain. The Federal Emergency Management Agency, FEMA, conducts flood insurance studies to identify a community's flood risk. The flood risk study is based upon statistical data for river flow, storm tides, hydrologic and hydraulic analyses, and rainfall and topographic surveys. The FEMA maps only provide a one-time snapshot of a flood, and do not describe the full extent of the flood event including the spatial and temporal variability of various flood events. Questions, such as the changes in flood inundation extent with time for the city of Zanesville, cannot be fully explored using the FEMA maps. It has been shown that accurate mapping of urban flooding events must take hydraulic connectivity and mass conservation into account (Bates, et al., 2005). In other words, extending potential flood elevations along lines of equal elevation given a river elevation, the so-called "Planar GIS method," may be inadequate for characterizing urban flooding. An alternative approach involves the simulation of hydraulic processes, which would control flooding and inundation patterns in downtown Zanesville given the FEMA 100 year Muskingum River main stem water surface elevation. Such an approach provides the framework, not only for producing dynamic maps of different frequency flood events for the city of Zanesville, but also evaluating the impacts of adding and/or removing structures or changing land use on urban flooding. Model simulations of the 100 year flood defined by FEMA have been created as part of this research. In addition, a 1D HEC-RAS model was built to compare 100 year flood profiles with the 2D LISFLOOD-FP model. The LISFLOOD-FP model agrees with the FEMA flooding map in spatial extent, and in river height predictions to within 1 foot. A 1-D HEC-RAS model also agrees with both the FEMA and LISFLOOD-FP model predictions. Sensitivity tests indicate that a flood wave with a flow rate of 100,000 cubic feet per second would be required to inundate downtown Zanesville.

Available in PDF, EPUB and Kindle. Book excerpt: Flooding is the most common and single largest source of disaster-caused property damage in the United States. The past year, 2017, was the costliest for weather and climate disasters in US history. To mitigate these losses, the Federal Emergency Management Agency and National Flood Insurance Program produce Flood Insurance Rate Maps (FIRMs) that often provide the most comprehensive and authoritative flood hazard information for a community. Despite reform efforts for greater map accuracy, spatial politics may render the computationally efficient 100- year floodplain delineation of questionable effectiveness, equity, and legitimacy for long-term land use planning. Given changing coastal flooding and sea level rise, how can risk mapping inform and improve future urban development? The dissertation: (1) positions flood mapping in the larger context of urban risk computation; (2) chronicles and statistically analyzes the nationwide map adoption process; (3) uses spatial analysis, document review, semi-structured interviews, and grounded theory to identify how these updates are proxies for nonstationary flood risk in Plymouth County, MA and New York City, NY; (4) compiles a novel survey of recent large-scale development decisionmaking in Boston, and (5) pilots a probabilistic indicator that models project-level flood risk information. I observe that the differences in location, wealth, and race between counties are associated with varying FIRM adoption process durations as well as whether a county may appeal and receive revised maps. I argue that coastal communities with sociopolitical clout can bend the process of computational risk assessment, through either contestation or collaboration over risk classification. I find the planning information shock of updated maps, however, is a largely insufficient signal to change developer behavior. Therefore, I pioneer the Future Flood Resilience Indicator (FFRI) as a decision support tool for developers to understand the long-term flood risk of their proposed development projects and planners to ascertain the impact of their policies. In conclusion, the dissertation provides policy makers with: (1) new data on how map adoption is not a purely scientific and technical process, (2) further evidence that the current 100- year flood standard is inadequate, and (3) resilience-building tools for land use planning.

Book excerpt: 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.

This book was released on 2010 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive Preparedness Guide (CPG) 101 provides guidelines on developing emergency operations plans (EOP). It promotes a common understanding of the fundamentals of risk-informed planning and decision making to help planners examine a hazard or threat and produce integrated, coordinated, and synchronized plans. The goal of CPG 101 is to make the planning process routine across all phases of emergency management and for all homeland security mission areas. This Guide helps planners at all levels of government in their efforts to develop and maintain viable all-hazards, all-threats EOPs. Accomplished properly, planning provides a methodical way to engage the whole community in thinking through the life cycle of a potential crisis, determining required capabilities, and establishing a framework for roles and responsibilities. It shapes how a community envisions and shares a desired outcome, selects effective ways to achieve it, and communicates expected results. Each jurisdiction's plans must reflect what that community will do to address its specific risks with the unique resources it has or can obtain.
