Predicting and Equipping Private Well Owners at Risk of Microbial Contamination After Flooding Events in the Alabama Black Belt
… failures due to soil conditions combined with flooding from frequent storms have created a groundwater quality epidemic in the Black Belt region of Alabama.Floodwater can infiltrate wells for extended periods, potentially exposing households to Escherichia coli (E. coli) and fecal coliforms. …

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 …

Assessing the Global Threat of Coastal Flooding: A Mortality Risk Model
Coastal flooding, caused by sea level rise (SLR), storm surge, and tropical cyclones, is a growing threat. Previous studies have documented mortality associated with historical coastal flooding and developed predictions of mortality risk based on SLR and human development. This study updates those …

Late Holocene Climate-Flood Relationships on the Lower Ohio River
The frequency and magnitude of flooding events on the Lower Ohio River and their relationship with climate are investigated using a ca. 2000-year-long sediment core collected from Goose Pond, Indiana. Using high-resolution radiocarbon dating (n = 25), late Holocene sedimentation rates were …

On a New Framework for Detecting, Classifying, and Forecasting Floods for Large-scale Flood Risk Analysis
<p>Increasing trends in flooding events are projected to continue as climate changes have increased the chance of extreme weather events. Given the significant, damaging impacts of extreme floods, the ability to effectively model floods is crucial for risk management and mitigation of the impacts …

Phosphorus Retention and Transformation in Floodplain Forests of the Southeastern United States
… GA).;To assess the nature of P removal during flooding events, I conducted a detailed study of DP and PP forms (inorganic, Pi and organic, Po) in waters from alluvial (AL) and blackwater (BW) FFs. At each FF site, floodwaters were collected both from the river inflow point (RI), from within the …

Estimating Health Risks Associated With Flooding Following Hurricane Harvey Using Earth Observations and the CDC Social Vulnerability Index
… between health records of outcomes related to flooding demarcated by satellite observations will be helpful to evaluate the use of satellite observed products in the mitigation of health risks for future flood events. The Centers for Disease Control and Prevention Social Vulnerability Index …

Identification and generation of new germplasms in barley with increased tolerance to waterlogging
… as Ireland is predicted to have increased flooding events. In consequence, the identification and development of barley varieties that are more tolerant to waterlogging has become an important research focus. The N-end rule protein degradation pathway has been shown to play an important …

Trends in stream power and erosion at a suburban stream in Western New York
… along with the frequency of high intensity storm events, have risen markedly in recent decades. Cross Canal Brook is a small stream east of Rochester, NY, and a tributary to Irondequoit Creek, where erosion and flooding events have seen a recent rise that has disturbed the local ecology and …

Survival and space use of riparian muskrats (Ondatra zibethicus) within an agroecosystem
… times of radiomarked individuals during flooding events in relation to landscape position. I used known-fate models and an information-theoretic approach to examine effects of age, season, hydrology, and riparian width on weekly survival rates. As expected, muskrats positioned farther …

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 …

Tropical cyclones within the sedimentary record : analyzing overwash deposition from event to millennial timescales
… overwash frequency, the magnitude of these flooding events has remained relatively constant. Stochastic simulations of hurricane overwash show that breaks in activity at Vieques are extremely long and unlikely to occur under the current hurricane climatology and the present barrier …

Spatial and temporal variability in floodplain sedimentation during individual hydrologic events on a lowland, meandering river: Allerton Park, Monticello, Illinois
… systems, vertical accretion dominates. Overbank flooding and floodplain inundation are dependent on bank height and local topographic variability and this leads to highly variable deposition both spatially and temporally. In order to better understand the dynamics of flooding, single flooding …

NUMERICALLY MODELING FLOODING SUSCEPTIBILITY OF THE UNITED STATES NAVAL ACADEMY
Urban flooding affects many of the world’s low-lying, coastal cities today. Whether induced by prolonged periods of rainfall, storm surge, or river overtopping, these issues pose as a hazard to human life as well as a source of damage to urban infrastructure. The United States Naval Academy is one …

Establishing uranium migration parameters for the Indian Springs Range
… of motile playa layers subject to sporadic flash flooding events. Using these values in the Residual Radiation (RESRAD) computer code resulted in an individual's first year total dose of 35 mrem under a resident farmer scenario. A sensitivity analysis was performed on several parameters, …

Enhancing Community Risk Preparedness for Flooding Emergencies: A System Dynamics Approach for the U.S. Army Corps of Engineers
Flooding events pose a significant and growing threat to communities in the United States, particularly as climate change alters weather patterns and sea levels continue to rise. This thesis examines how the U.S. Army Corps of Engineers (USACE) can enhance community preparedness for flood …

Development of flood prediction models using machine learning techniques
"Flooding and flash flooding events damage infrastructure elements and pose a significant threat to the safety of the people residing in susceptible regions. There are some methods that government authorities rely on to assist in predicting these events in advance to provide warning, but such …
