Modelling the effects of excavation pits on fringing reefs

Many small island developing states (SIDS) are among the most vulnerable to climate change (e.g. sea level rise) and seasonal to inter-annual climate variability, and subsequently experience flooding due to swell waves and wind waves, coastal erosion and salinisation of freshwater lenses. To counteract this, reef flat mining for sand and...

Upscaling coastal flood risk assessment - Insight into the uncertainty of a continental-scale model

During the last years, flood risk assessments at continental and global scales are emerging as useful tools for risk hotspot identification, support for international policy-making and harmonization of strategies for climate change adaptation. The emergence of these models comes to cover the growing demand for integrated, large-scale risk...

Modelling of Grain Sorting Mechanisms in the Nearshore Area for Natural and Nourished Beaches

In this study a modelling approach was investigated that takes into account the effect of short wave grouping on long wave motions, calculating sediment transport and morphology with multiple fractions and a layered bed stratigraphy. After extensive testing and validating this model using data collected in a wave flume in Hannover this model was...
