Assessing the ecological vulnerability of natural flood defences and risks to agricultural land following seawater flooding
… the frequency and severity of storm surge flooding in low-lying coastal regions is projected to increase under future climate scenarios. There is a growing need to understand how these events will impact coastal ecosystems, and the measures that can be taken to mitigate against these …

Probabilistic deterioration modelling and time-dependent reliability analysis of coastal defences
The prediction of coastal flood defence performance deterioration in the future plays an essential role in the reliability analysis and management process of these structures. The climate change effects and sea level rise will increase the hydraulic loads and frequency of the future extreme events, …

MPM study of water wave interaction with porous seawalls
Flood defences are becoming increasingly vital for protecting key coastal infrastructure from rising sea levels and storm surge waves. Waves attenuate rapidly as they propagate through porous media, corresponding to significant energy dissipation. The ability of porous armour layers to absorb wave …

A reliability rating system for flood embankments in the United Kingdom
The probability of structural failure of flood defences is an important component in the modelling of flood risk. Flood embankments are a very common type of defence whose reliability assessment shows some problematic aspects. In particular it is difficulty to model the process of piping through …

The potential alternative uses of dredged material in the Humber Estuary
… by the Environment Agency (EA) has having flood defences in less than favourable condition. These locations were characterised by the sediment type, quantity of material needed to ensure protection, average flow velocities at the sites and distance from the dredge site.By disposing of this …

Salt marsh substrate composition and responses to applied stress
… implementation of both nature-based coastal flood defences, and coastal restoration schemes.

Battle for the Floodplains: An Institutional Analysis of Water Management and Spatial Planning in England
Dramatic flood events witnessed from the turn of the century have renewed political attention and, it is believed, created new opportunities for the restoration of functional floodplains to alleviate the impact of flooding on urban development. For centuries, rural and urban landowning interests …

Challenges of Transformative Adaptation: Insights from Flood Risk Management
… fails, using two case study locations of flood risk management in Ireland as examples of adaptation in practice (Clontarf, County Dublin and Skibbereen, County Cork). Employing in-depth qualitative and quantitative research methods, this thesis finds that i) barriers to transformative …

Statistical models for extreme weather events
… which typically take the form of windstorms or flooding. The storm Desmond brought strong winds and heavy rain to Ireland, northern England and Scotland in December 2015, resulting in an estimated $500 million worth of damage and extensive flooding, particularly in the region of Cumbria. …

An Assessment into the issues created by surface water flooding within the Rhondda Cynon Taf County Borough, Wales
Recent flooding events including the February Storm Dennis and June 17thfloodshave shown that the situation faced by the RCT County Borough will only worsen with the advent of climate change, increasing the frequency and damage caused by the occurrence of repeated winter storms. One of the key …

Impacts of anthropogenic activities on the fisheries of the Don, Rother and Dearne catchments
… channels have been modified for navigation, flood defences and hydro-electric power generation. These modifications to the river system disrupt the fabric of the aquatic ecosystem and diminish its integrity, affecting equally the capacity of fish and other organisms to survive. Fish depend on …

Exploring fine sediment dynamics and the uncertainties associated with sediment fingerprinting in the Nene river basin, UK
… of; sediment yield, sediment provenance, floodplain sediment accumulation and channel bed sediment storage. A mean difference of 24.1% between the predicted contributions of sediment originating from channel banks was found when using nine different tracer groups to fingerprint the river …
