Landslide problems in Winnipeg

Abstract

Winnipeg is built on lacustrine, swelling, plastic clays, and is intersected by two major rivers, and other smaller rivers. The riverbanks are used for commercial, residential, and public utility purposes, and many are unstable. This paper reviews the conditions of topography, river flooding, and soil properties which have produced sliding in the riverbanks. The framework of legislation which governs riverbank development is reviewed, and procedures for stability analyses are outlined. The paper concludes by discussing current design practices, and their application to stabilising measures for common practical problems in the city.
