Continuous, near-real time predictions of winter flooding are critical to balancing the protection of life and property with providing water resources for consumptive use in California’s northern Sierra Nevada. Rain-on-snow (ROS) events are a major cause of floods in the region …

From 1959 – 2009, Texas has annually led the nation in the number of flood fatalities. On average the number of deaths in Texas was three times the amount of the second leading state (Sharif, Hossain, Jackson & Bin-Shafique, 2012). Quantitative studies have attempted to cons…
Riparian zones are areas along waterways that are typically covered by woody vegetation, herbaceous plants, and grasses. Flooding is an important process in riparian habitats as it continuously causes net gains and losses of substrates in riparian communities that determine the …
In this thesis, a complex depth-averaged model is developed for simulating heat and fluid flows in vegetated channels, with a capability to simulate dam-break and flooding phenomena. The model is able to simulate both laminar and turbulent flows, it can take the secondary flow e…
The importance of gubernatorial discretion in managing major disasters cannot be overstated. The role of the state governor, as the state government's chief elected official, is central to effective disaster response and recovery operations. More importantly, the latitude of dis…
Flooding is the most frequently occurring natural hazard on Earth; with catastrophic, large scale floods causing immense damage to people, property, and the environment. Over the past 20 years, remote sensing has become the standard technique for flood identification because of …
Black spruce (Picea mariana (Mill) B. S. P.), an evergreen conifer and tamarack (Larix laricina (Du Roi) K. Koch), a deciduous conifer, are the predominant tree species of boreal peatlands of northern Alberta, Canada. The harsh boreal environment is characterized by low nutrient…
Flooding has the potential to have significant impact on the value of properties depending on the level of inherent vulnerability. Experts argue that it is not the actual risk but the perception of risk among property holders that influences vulnerability of value. The hypothesi…
Amazonian tropical forests account for 20-50% of global primary productivity and up to 40% of carbon stored in terrestrial biomass (Phillips et al., 1998). The Amazon is also home to the Earth’s largest river system, accounting for approximately 20% of the world’s total river di…
Enhanced oil recovery (EOR) screening is considered the first step in evaluating potential EOR techniques for candidate reservoirs. Therefore, as new technologies are developed, it is important to update the screening criteria. Many of the screening criteria for steam flooding t…
Malaysia has a monsoon climate and most areas receive more than 2,500 mm of rainfall every year. For the past five years, the frequency and magnitude of floods in Malaysia have been relatively high. Floods have become the most significant type of natural disaster for Malaysia in…
The use of gas in alkaline-surfactant flooding (Alkaline-Surfactant-Gas (ASG) process) can be an alternative to the use of polymer, especially in carbonate reservoirs that generally have low permeability and contain vugs and fractures, for improving the displacement efficiency. …
This study aims to develop models predicting the depth, extent and volume of flooding in the Hadejia-Nguru wetlands of Nigeria from satellite sensor images. In subregions representative of the entire wetlands over 1,500 rigorously coordinated and geocoded depths were observed, s…
Flood events occur annually causing damage to communities and transportation networks. A loss of performance can greatly affect populations socioeconomically many years post-event. Restoring these damages as efficiently and effectively as possible is imperative. Quality asset ma…
Tropical cyclones (TCs) pose a persistent threat to North Carolina. The state’s coastal plain and outer banks lie between 78 and 75 degrees W, farther east than any other southeastern state. In the last 150 years there have been more than 400 tropical and subtropical cyclones th…
Fort Collins, Colorado, home to over 150,000 people along the northern Front Range, is prone to flood. This natural disaster threat is not a recent development nor a strictly natural problem. Rather, flooding in Fort Collins is informed by the interaction of the local environmen…
