Adapting the Robust Effect Size Cliff’s Delta to Compare Behaviour Profiles

Cliff’s Delta is a non-parametric effect size that is based on data observations. In this paper, we elaborate on an adaptation of Cliff’s Delta in order to compare behaviour profiles. Behaviour profiles are density distributions in which survey answer behaviour is summarized for specific groups of respondents or items. Such profiles are...

Marine erosion of the Point Grey cliffs: A nearshore hydrodynamic, sediment transport and budget study

At the edge of Vancouver and the Strait of Georgia the Point Grey cliffs experience marine and subaerial erosion. The retreat of the cliffs will eventually result in losing university assets, infrastructure and archaeological treasures. Wave-induced sediment transports are supposed to be the main marine erosion mechanism. This report presents...

Cliff Erosion at Point Grey UBC: A feasibility study of preliminary concepts to deal with erosion

Erosion of the cliffs at the Point Grey Peninsula threatens important infrastructure and buildings at UBC. In order to tackle this problem, UBC launched a comprehensive project called Living Breakwaters. This project is part of Living Breakwaters and aims to act as a transversal element among different expertise, integrating these...

Monitoring Cliff Erosion with LiDAR Surveys and Bayesian Network-based Data Analysis

Cliff coasts are dynamic environments that can retreat very quickly. However, the<br/>short-term changes and factors contributing to cliff coast erosion have not received as much attention as dune coasts. In this study, three soft-cliff systems in the southern Baltic Sea were monitored with the use of terrestrial laser scanner technology over a...

Cliff Retreat Induced by Series of Storms at Miȩdzyzdroje (Poland)

In Miȩdzyzdroje, a coastal town in Poland, significant cliff retreat has been observed in recent times. It used to be considered mainly a response to storm events with particularly high water levels and wave energy. However, morphology of cliff coasts is shaped not only by the most extreme storm surges or by a number of accompanying processes...

Process data analysis: Using a Bayesian Network approach to model processes in the Marine Contracting practice

Marine contractors deal with processes that are understood qualitatively but are hard to quantify. The amount of data available for these processes is ever growing, and so too the intrinsic value that lies within this data. Several data driven model approaches can be used to analyse this process data, one being a Bayesian Network (BN) approach....

English and Dutch Method of Shore Protection

Discusion between van Veen and Minikin on the effectivity of groynes. Reading this discussion one should realise that at that time there was no clear understanding of wave driven longshore currents.
