BEACH AND DUKE EROSION TESTS

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...

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...

Numerical modelling of concentrated leak erosion during Hole Erosion Tests

This study focuses on the numerical modelling of concentrated leak erosion of a cohesive soil by a turbulent flow in axisymmetrical geometry, with application to the Hole Erosion Test (HET). The numerical model is based on adaptive remeshing of the water/soil interface to ensure accurate description of the mechanical phenomena occurring near the soil/water interface. The erosion law governing t...
