The magnitude and extent of fluvial, tidal and storm surge flooding in coastal Bangladesh are quantified using hydrodynamic numerical models under a series of climate and sea-level rise scenarios to 2100. Fluvial floods occur from July to October and are confined to the northern part of the ...
The duration offloodingand the salinities of the sediments andtidal waterscontrol the mix of higher vegetation. Competitive interactions between plants and interactions between plants and animals further determine plant distributions. Duration of flooding duration controls how saturated the sediments will be...
Coastal tidal wetlands produce and accumulate significant amounts of organic carbon (C) that help to mitigate climate change. However, previous data limitations have prevented a robust evaluation of the global rates and mechanisms driving C accumulation. Here, we go beyond recent soil C stock estima...
The generation and evolution of tidally-induced vortices in coastal and estuarine regions can influence water quality and sedimentary processes. These effects must be taken into consideration in the development of coastal reservoirs, barrages and lagoons, among other environmental flow applications. Results...
9. At this site the currents are flood dominated, pealung at 33 cm B - S ~ t e3 in June S-' within 30 min of flooding, and then declining rapidly to slack water. This coincided with a peak in the SPM of 500 mg 1-' in the shallow flood water, a depth comparable to that of...
levels and Storm surge penetration into NSW for an OEH research project on Tidal Limits and Flooding Tailwater Levels at NSW Coastal Entrances (Stage-I and II). That study has identified that significant losses in tidal amplitude occur at or within the estuary entrances for a range ...
Our projection methodology captures how observed flood rates depend on how storm surges coincide with tidal extremes. We show that higher flood rates and earlier emergence of chronic flooding are associated with larger sea‐level rise rates, lower flood thresholds, and increases in tidal...
Storm surgeSevern BarrageThe proposed Severn Barrage is a controversial but widely discussed proposal to generate clean and renewable energy. A key concern with this technology is that such structures may cause other environmental problems. However, such structures might also have beneficial environmental...
We now show that the loss of tidal flats may have resulted in harmful impacts of coastal storm flooding. Using the foreshore profiles measured before and after reclamation (i.e., wide vs. narrow tidal flat), we determined the long-term changes in flood risk using a numerical model that ...
Stress is placed upon the complex interaction of economic and environmental factors in determining the response to the threat of marine flooding.James A. GallowayJournal of Medieval HistoryGalloway, J. , ‘ Storm Flooding, Coastal Defence and Land Use Around the Thames Estuary and Tidal River c....
