Hydraulic modelling and flood inundation mapping in a bedrock-confined anabranching network: the Mekong River in the Siphandone Wetlands, Laos
… assumed to be similar to the gauged channels for flooding discharges).<br/>In general, the study has helped to develop methods to model the complex river network with<br/>data constraints (i.e. the boundary conditions). The findings include: (i) the developed<br/>pseudo-bathymetry based on a SPOT …

Hydraulic Modeling of a River Network for Predicting Flood Inundation using HEC-RAS and GIS Models - A Case Study in Southern Virginia
A flood inundation study is presented for a watershed located in south central Virginia. A HEC-RAS hydrodynamic model of the main river network was developed to assess the impact of a number of hydrologic events, including the Probable Maximum Flood (PMF), in the area of interest. The primary goal …

Evaluating Changes in Terrestrial Hydrological Components Due to Climate Change in the Chesapeake Bay Watershed
… Using these long-term simulations, the flood inundation maps are developed for future scenarios along the Susquehanna River including the City of Harrisburg in Pennsylvania. The HEC-RAS 2D model is calibrated and evaluated against the high-water marks from major historical flood events …

The development of an interactive computer model for managing geologic hazard databases
… earthen dams are subjected to ever increasing flood events, a more proactive management system is required in order to provide timely information to planners and emergency personnel on demand. In recent years, deaths have occurred associated with both highway rockslides and earthen dam failures …

Validating the Quality of Crowdsourced Data for Flood Modeling of Hurricane Harvey in Houston, Texas
Flood is one of the most widespread natural hazards in the world. Hurricane Harvey, a 1000-year flood event, hit Texas in 2017 and resulted in significant property damage, bodily injury, and casualty. As one of the most impacted areas, Houston is chosen to be the study area of this study. For …

Flood Disaster Resilient Bridge Structures For Sustainable Bridge Management Systems
… at an increasing ferocity and frequency. Floods are the most comand damaging natural disaster. More than 4,400 occurrences of flood disasters have been reported globally between 1900 and 2016. As a result, around seven million people were killed and millions more were displaced. Climate …

Hydrologic Modeling of a Probable Maximum Precipitation Event Using HEC-HMS and GIS Models - A Case Study of Two Watersheds in Southern Virginia-
… hydrographs associated with the Probable Maximum Flood (PMF) at key locations in each of the watersheds. These hydrographs were subsequently used to develop flood inundation maps of the study areas and to characterize sediment transport phenomena in the study reaches under severe flooding …

A Prescriptive Criterion for Amphibious Foundation Design
<p>Flooding is the most frequently occurring natural disaster in the United States and worldwide (FEMA, 2004). Each year, when major flooding ravishes communities, residents are put in danger and often displaced from their homes and jobs for several weeks or months, if not more. The use of …

Floodplain Risk Analysis Using Flood Probability and Annual Exceedance Probability Maps
… and model uncertainty on the extents of computed floodplain boundaries. The first approach represents the floodplain boundary as a spatial map of flood probabilities -- with values between 0 and 100%. Instead of representing the floodplain boundary at a certain recurrence interval as a single …

Rapid flood damage prediction in short lead-time scenarios
Research on short lead-time flood inundation and damage assessment traditionally focuses on developing tools for long term planning. Studies that investigate the ability to provide short lead-time analyses are uncommon because of sparcity and spatial inconsistency of short-term hydrologic …

An investigation of hydraulic and GIS processes to inform environmental justice decision-making regarding 10 percent annual chance flooding events
… public regarding 10-year annual chance pluvial flooding events. This leaves communities, individuals, stakeholders, and advocates with very few resources available to them to evaluate and determine the risks and health hazards associated with these more recurrent flooding events. Almost all …

Hydraulic modeling and performance evaluation of low water crossings in Illinois
… low-volume roads where there is a low number of floods. The lack of design guidance has posed difficulty for county engineers in Illinois in deciding when, where, and which type of low water crossing to use. The resulting structure is often either overdesigned or underdesigned. A study was …

Evaluating Future Runoff, Water Stress and Fluvial Flooding in China under Climate Change
… in runoff variability, water stress, and fluvial flood hazards under climate change and socioeconomic development. Understanding how these processes may evolve under future scenarios is critical for long-term water resource planning and climate adaptation. However, existing studies often suffer …

Flood risk assessment using multi-sensor remote sensing, geographic information system, 2D hydraulic and machine learning based models
Flooding events threaten the population, economy and environment worldwide. In recent years, several spatial methods have been developed to map flood susceptibility, hazard and risk for predicting and modelling flooding events. However, this research proposes multiple state-of-the-art approaches to …
