چکیده

Abstract. Beach erosion at the unprotected downdrift end of a groin is common with waves approaching structure obliquely. This phenomenon has often occurred on side natural groins east coast South Korea during high in winter months. The resulting planform assumes distinctive crenulate shape maximum indentation point landward erosion. An analytical model employed to study beach rock Jeongdongjin Korea, using mathematical equations derived from parabolic for headland-bay beaches static equilibrium, predict control and eroded shoreline. These are solved prevailing wave height, angle breaking direction analyzing NOAA's data over 40 years longshore sediment transport rate calculated data. location also verified shoreline video monitoring compared result one-line numerical change. limitation proposed discussed as effect bypassing groin.

Economic Valuation of Beach Erosion Control Programs

In this study, we employ a choice-based conjoint survey design to elicit individual choices of beach erosion control programs that can potentially cause multiple effects on beach environment. Two empirical choice models which incorporate individual heterogeneity, are used to analyze and compare the elicited individual choices of erosion control programs. Our results show that to a typical indiv...

Environmental Impact of Beach Nourishment: A Case Study of the Rio San Pedro Beach (SW Spain)

The beaches on the left bank of Rio San Pedro (SW Spain) are in a regressive state because of the human activities of recent decades. With the objective of minimizing the effects of the erosion, the Spanish Coastal Department (Ministry of the Environment) decided that the most suitable solution was to provide sand nourishment. Previously, an environmental impact study (EIS) was carried out on t...

An holistic approach to beach erosion vulnerability assessment.

Erosion is a major threat for coasts worldwide, beaches in particular, which constitute one of the most valuable coastal landforms. Vulnerability assessments related to beach erosion may contribute to planning measures to counteract erosion by identifying, quantifying and ranking vulnerability. Herein, we present a new index, the Beach Vulnerability Index (BVI), which combines simplicity in cal...
