Abstract Global mean sea-level rise (SLR) has accelerated since 1900 from less than 2 mm yr −1 during most of the century to more 3 1993. Decision-makers in coastal countries, however, require information on SLR at regional scale, where detection an acceleration is difficult, because long-term signal obscured by large inter-annual variations with multi-year trends that are easily one order magn...

[1] The rate of sea level rise and its causes are topics of active debate. Here we use a delayed response statistical model to attribute the past 1000 years of sea level variability to various natural (volcanic and solar radiative) and anthropogenic (greenhouse gases and aerosols) forcings. We show that until 1800 the main drivers of sea level change are volcanic and solar radiative forcings. F...

Sea level rise could alter the boundary conditions of tidal rivers. This in turn would modify the hydrodynamic behaviour of coastal rivers and consequently their backwater rise. This paper presents the effect of modified boundary conditions on river peak stage and flow resulting from probable levels of sea level rise on the west coast of Peninsular Malaysia. The study site is a tidal affected r...

Sea-level rise is a major effect of climate change. It has drawn international attention, because higher sea levels in the future would cause serious impacts in various parts of the world. There are questions associated with sea-level rise which science needs to answer. To what extent did climate change contribute to sea-level rise in the past? How much will global mean sea level increase in th...

Since the Mid-Holocene, some 5000 years ago, coral reefs in the Pacific Ocean have been vertically constrained by sea level. Contemporary sea-level rise is releasing these constraints, providing accommodation space for vertical reef expansion. Here, we show that Porites microatolls, from reef-flat environments in Palau (western Pacific Ocean), are ‘keeping up’ with contemporary sea-level rise. ...

many studies since 1977, in the southern coast of caspian sea revealed that the law-setback and low-lying coastal zone have been severely and increasingly impacted by rising sea-level. this rising continued until 1995. the rate of rising was nearly 13cm per year in this period (1977-1995). the general concept of setback determination is tended to introduce a buffer area between human activities...
