Hydrologic simulation of storm water detention storage in an urbanizing flood-plan
Emerging concepts of urban flood control consider the use of storage detention, especially where channel capacities are being overtaxed by urban runoff. Particular problems exist where high rainfall intensities and low topographic relief combine with rapid urban development to produce potential …

An Evaluation of a Hydrological Model Used to Predict the Impact of Flow Attenuation on Downstream Flood Flows
… high magnitude events have shown that fluvial flooding has increasingly detrimental impacts on people and properties. There is a perception that flood risk is increasing due to several factors, including urbanisation of floodplains and climate change. This has created a need to assess the …

Transient Seepage Analysis for Levees and Dams: Numerical and Monitoring Approaches
An investigation into the transient impacts of flood loadings on earthen embankments was conducted. Two embankments were instrumented and monitored over a period of four years. One of these embankments was a levee located along the Mississippi River just north of Cairo, Illinois. The other …

An assessment of tidal energy and the environmental response to extraction at a site in the Pentland Firth
… such as displacement and misalignment of peak flood and ebb tides, which must be considered when contemplating the exploitation of this energy resource. Tidal stream turbines were simulated in the hydrodynamic model. Artificial energy extraction was parameterised at the sub-grid-scale via …

The effects of future extreme precipitation events on stream hydrology and hydraulics of stream crossing structures
… training and extreme storm events and associated flooding risks can temporarily limit access to training lands and other training features such as water crossings. If an increase in intensity and incidence of extreme precipitation events is realized, installations associated with river systems are …

Hydroclimate Drivers and Atmospheric Dynamics of Floods
… survey showed that most of the recent flood-related studies did not formally explain the physical mechanisms of long-duration and large-peak flood events that can evoke substantial damages to properties and infrastructure systems. These studies also fell short of fully assessing the …

Lion population status and ecology in a seasonally-flooded wetland, the Okavango Delta
… ecological change in response to an annual flood pulse, the extent of which is determined by both short-and long-term climatic variation. The resulting fluctuations in landscape structure and resource availability affect all trophic levels. However, their effects on apex predators are not …

Hypsometric and geometric controls on hydrodynamics, tidal asymmetry, and sediment connectivity in shallow estuarine systems
… small bed shear stress values and high rates of flood-directed tidal velocity asymmetry in the sheltered basin centres. These results suggest substantial potential for sediment deposition of larger particles. Moreover, slack water asymmetry within these basins was weakly ebb-directed, indicating …

Application of open-access and 3rd party geospatial technology for integrated flood risk management in data sparse regions of developing countries
Floods are one of the most devastating disasters known to man, caused by both natural and anthropogenic factors. The trend of flood events is continuously rising, increasing the exposure of the vulnerable populace in both developed and especially developing regions. Floods occur unexpectedly in …
