Abstract
Thispaperpresentsagenericframeworkforassess- ing inherent climate change hazards in coastal environments through a combined coastal classification and hazard evalua- tion system. The framework is developed to be used at scales relevant for regional and national planning and aims to cover all coastal environments worldwide through a specially designed coastal classification system containing 113 generic coastal types. The framework provides information on the degree to which key climate change hazards are inherent in a particular coastal environment, and covers the hazards of ecosystem disruption, gradual inundation, saltwaterintrusion, erosion and flooding. The system includes a total of 565 individual hazard evaluations, each graduated into four differ- ent hazard levels based on a scientific literature review. The framework uses a simple assessment methodology with lim- ited data and computing requirements, allowing for applica- tion in developing country settings. It is presented as a graphical tool—the Coastal Hazard Wheel—to ease its appli- cation for planning purposes.
Highlights
The growing concern for global climate change has spurred research into methods for assessing climate-related vulnerability of coastal environments at local, regional and national scale
This paper presents a generic framework for simple assessment of climate change hazards in coastal environments without the need for excessive data collection or computer processing capacity
The framework aims at covering virtually all coastal environments worldwide through a specially designed coastal classification system building on key bio-geophysical parameters. It provides information on the climate change hazards considered most relevant for coastal management (Zhu et al 2010)
Summary
The growing concern for global climate change has spurred research into methods for assessing climate-related vulnerability of coastal environments at local, regional and national scale. Since the effect of tidal range on the inherent hazards of sloping soft rock coasts, sloping hard rock coasts and coral islands is considered to be minor, the any tide category has been applied to these layouts for simplification purposes. Coastlines with a flat geological layout such as coastal plains, barriers, deltas and coral islands generally have a higher inherent hazard level.
