Reading the Reach: A Novel, Systematic, GIS-Based Approach to Erosion Hazard Mapping in Asset Management

Wednesday March 27, 2024 | 3:15 to 3:45 p.m. | Hall F


The Regional Municipality of Peel, like many other municipalities, faces the challenge of improving their asset management programs. With rapidly growing communities and the necessity of increasing climate change resiliency, implementing effective asset management strategies is imperative.

There are over 56,000 sanitary maintenance holes and nearly 2,000 kilometers of regulated watercourses located within the Region. As a result of the quantity of maintenance holes and the density of regulated watercourses within the Region, many of these maintenance holes are susceptible to erosion as a result of ongoing geomorphological processes.

Managing such a large asset portfolio can prove daunting, with each maintenance hole being exposed to a variety of influences that result in a varying degrees of erosion risk.

This presentation will discuss a novel approach to identify, screen, and prioritize the maintenance holes facing risk of erosion as a result of fluvial geomorphological processes. The methods used for analysis will be discussed, along with their effectiveness, and it will be shown how the results were then used to develop a Multicriteria Analysis Tool to rank and prioritize the maintenance holes for mitigation.

It is desired that this presentation stimulates discussion of how the integration of geomorphology into asset management can aid municipalities in improving their resilience to climate change and the efficiency of their asset management programs.
