Feasibility of the Erosion Protection Concepts

Project by Irene Cantoni, Camilla GaidoTessa Jonker, and  Laurie van Gijzen

Project team includes Kees Lokman, Tugce CongerDoug DoyleAmir Taleghani, and David Gill


The problem

The cliffs consist of sand with an unconsolidated nature and consequently a low shear strength, which makes them prone to instabilities and erosion. The erosion of the Point Grey cliffs threatens key infrastructure and buildings at the University of British Columbia’s Vancouver campus as well as important cultural and social assets of the local and regional community.

Overtime, several studies have investigated the causes of the cliff’s erosion. But studies on understanding what adaptation options can be implemented, and the feasibility of the range of these adaptation options have been missing.

The objectives

The project had five main objectives:

  • Provide an overview of the study area and the factors contributing to cliff erosion;
  • Give an outline of the stakeholders involved and present a legislative framework for possible erosion solutions;
  • Identify a toolkit of measures to tackle cliff erosion with hard, hybrid and soft solutions;
  • Develop four concepts for dealing with cliff erosion, and conduct a feasibility study for each of them in terms of technical, environmental, economical, legislative and social aspects; and
  • Give insight in the existing knowledge gaps and missing data
