Erosion Risk Assessment of Active Coastal Cliffs in Temperate

The potentially negative consequences resulting from cliff recession are a matter of serious concern in many coastal areas worldwide. The assessment of these kind of processes has traditionally been performed by calculating average cliff recession rates and projecting them into the future, without taking into consideration the diverse factors affecting cliff dynamics and stability. In this work...

Operationalization of Sar Polarized Data for Assessment of Coastal Erosion

This study introduces a new approach for operationalization of SAR polarized data on coastal erosion studies. Polarized TOPSAR and ERS-1 data are used for this purpose. ERS-1 data was acquired on the 8 August 1993 and polarized TOPSAR data was acquired on the 6 December 1996. A quasi-linear model and a new model based on the Canny algorithm were used to model shoreline changes. Digitized vector...

Reliability, return periods, and risk under nonstationarity

Water resources design has widely used the average return period as a concept to inform management and communication of the risk of experiencing an exceedance event within a planning horizon. Even though nonstationarity is often apparent, in practice hydrologic design often mistakenly assumes that the probability of exceedance, p, is constant from year to year which leads to an average return p...

A Decision Support Framework for the Risk Assessment of Coastal Erosion in the Yangtze Delta

Coastal erosion is an issue of widespread concern. As one of the most important economic regions in China, the coast of the Yangtze Delta has been showing a trend towards erosion with global warming and the increasing human activities in the catchment and its estuary. Currently, most published studies about coastal erosion in the area focused on the causes and types of erosion. This paper prese...
