Stantec releases new landslide runout software to help protect communities and infrastructure from destructive mountain hazards
DebrisFlow Predictor helps landslide professionals predict runout and potential impacts from debris flows and debris avalanches
EDMONTON, AB; NEW YORK, NY (July 6, 2021) TSX, NYSE:STN
Global design firm Stantec has developed a new software program that can reasonably predict the path – and potential impacts – of landslides. Designed by Stantec experts, DebrisFlow Predictor, is a cost-effective solution to help the firm’s landslide professionals protect people, the environment, and infrastructure from the threat of debris flows and debris avalanches.
Dr. Richard Guthrie is the lead scientist behind DebrisFlow Predictor. He calls the predictive software a new solution to an old problem.
“Our team designed DebrisFlow Predictor to complement expert judgment,” says Guthrie. “This software predicts a landslide’s path, the depth along the path, and the total area and volume of the debris flow. Better yet, it is efficient to deploy, works with limited data inputs, and can be applied to a very large surface area. To date, there is no other program like DebrisFlow Predictor.”
Formerly known as LABS, DebrisFlow Predictor operates on the principles of sediment balance using cellular automata, a set of cells or agents that act on a grid that evolves over a series of discrete time steps according to a set of rules and the state of neighboring cells. In this manner, relatively simple rules that underlie the program produce complex dynamic behavior. DebrisFlow Predictor estimates the sediment volume along a landslide path by deploying 5-metre-sized agents over a digital elevation model of the same resolution.
“Debris flows are a type of avalanche that are most often triggered by rainstorms and earthquakes,” says Guthrie. “If the ground has been preconditioned for debris flows – such as during the wildfires in the state of California, which removed vegetation and created hydrophobic soils, the danger increases considerably.”
DebrisFlow Predictor will benefit:
- Communities and municipalities. If you live or work in, or adjacent to, mountainous terrain, DebrisFlow Predictor can help you better understand your hazards and your risk. Using the new technology can help protect vulnerable infrastructure through increased awareness, development of or improvements to your zoning by-laws, and by providing mitigation solutions where the hazard warrants.
- Linear Infrastructure. Telecommunications, pipelines, roads, fiberoptic. Linear infrastructure frequently crosses debris-flow paths and is threatened by scour (e.g., exposing the pipeline, destroying the road) and deposition (e.g., blocking and closing the road). The Predictor can help identify where this will occur and develop plans to reduce the impact.
- Mines. Debris flows from waste piles and mountainous terrain can threaten infrastructure and block access to mine facilities. We can help you navigate the hazard.
- Environmental. Whether due to fires, human activity, or natural causes (e.g. hurricanes and earthquakes), regional debris flow events can have serious impacts on the environment. Stantec’s team uses DebrisFlow Predictor to quantify the actual sediment transfer from slopes to streams or lower positions on the landscape.
