Coastal hazard management involves the assessment of vulnerability in natural and human environments. Indices incorporating a diversity indicators have therefore been used extensively to provide spatial analyses degree vulnerability. Such indices are typically applied at global national scales, they involve varying degrees simplification aggregation information. The that is desirable depends on scale, higher resolution required local compared scale. To investigate implications scale...
Today's understanding of sea-level change developed through a combination process-based physical modelling and observational data. Observational data derives from coral reefs in the far-field former ice sheets where geographically variable relative signal is expected as response earth to ocean loading. Given this variability limited geographical distribution reefs, there need explore other, non-coral based markers further understand and, for example, 'fingerprint' melt-water. Here, we...
Abstract A Late Quaternary sea-level curve for South Africa is presented on the basis of new and published data from a range sea level indicators variety locations. Available evidence suggests that in broadly follows described Caribbean but deviations occur during highstands. During last interglaciation (oxygen isotope stage 5) late Holocene, coastal emergence produced higher levels than those identified same time intervals. This tentatively ascribed to predicted lithospheric deformation...
The debate surrounding the sustainability of urban areas and need to reduce dependency upon car as primary mode transportation has rekindled interest in relationship between accessibility, price location owner occupied housing. Traditionally, attempts at quantification have used hedonic analysis employing straight-line distance measurements focal points such CBD an indicator accessibility. This paper focuses factors affecting structure residential property Belfast Urban Area, examining...
In the context of global climate change and sea-level rise, coastal dunes are often important elements in response to storm wave surge impacts on lowlands. Vegetation cover, turn, has profound dune morphology storm-buffering function; it binds existing sediment, promotes fresh sediment accumulation thereby increases volume crest elevation where a sediment-plant interaction plays out with vegetation growth attempting out-pace vertical accumulation. A analysis shows that cover increased...
It has been asserted by Vousdoukas et al., that climate change, in particular global sea-level rise (SLR), poses a threat to the existence of sandy beaches. The authors used data bases beaches, bathymetry, wave conditions and SLR drive simple model based on ‘Bruun Rule’ quantitatively evaluate shoreline retreat. To this modelled retreat, they add background ambient trend dynamics response an extreme storm, together contribute c. 20% When retreat was more than 100 m 2100, declared those...
Most previously developed coastal vulnerability/sensitivity indices acknowledge that the addition of socio-economic variables would assist in defining vulnerable areas. This study investigated incorporation into a GIS based vulnerability index for wave-induced erosion Northern Ireland.In this application, sub-index was to contribute potentially one third overall score; other components consisted forcing and characteristic sub-indices. All were ranked on an arbitrary 1–5 scale with 5 being...
Most of the world's shorelines are in a state erosion, prompting search for ways to predict future rate shoreline retreat. In their Perspective, [Pilkey and Cooper][1] claim that simple mathematical relationship called Bruun rule is not suitable means calculating retreat except under limited range environmental circumstances.

The concept of ‘working with natural processes’ has wide currency in coastal zone management. It is one eight principles for integrated management listed a recent EU Recommendation. From geomorphological perspective, the concept, however, range imparted meanings that from (1) direct human intervention processes using ‘hard engineering’ structures causes alteration wave patterns, through (2) variety ‘soft approaches to (3) non‐intervention and proactively taking steps enable coastline...
ABSTRACT The Mgeni Estuary on the wave dominated east coast of South Africa occupies a narrow, bedrock confined, alluvial valley and is partially blocked at by an elongate sandy barrier. Fluvial sediment extends to barrier marine deposition restricted small flood tidal delta. Sequential aerial photography, sampling topographical surveys reveal cyclical pattern sedimentation that mediated severe fluvial floods which exceed normal energy thresholds. During (up 10x 10 3 m s −1 ), lateral...
The behaviour of offshore-directed winds over coastal dune and beach morphology was examined using a combination modelling (3-D computational fluid dynamics (CFD)) field measurement. Both model simulations measurements showed reversal offshore flows at the back creation an onshore sediment transport potential. influence flow reversals on beach-dune system foredune growth patterns has previously received little attention. Detailed wind were made extensive array mast-mounted, 3-D ultrasonic...
