Billions of dollars of new infrastructure will be built in steep terrain in Canada over the coming decade due to population growth and new natural gas, oil, and mining developments. People living or working near steep rock slopes and the associated infrastructure are exposed to geohazards. The long-term objectives of the research program are to improve geohazard assessment techniques and to build the missing links between geohazard assessment and the design of appropriate risk mitigation measures to reduce losses associated with rock falling from steep rock slopes. The short-term objectives address three deficiencies in the current risk management for steep rock slopes. Existing geohazard assessment methods can take too long and can expose geotechnical engineers doing the assessment to unsafe fieldwork. Overly simplistic geometric formulae (in current building codes) are used to define areas where it is safe to build; these formulae do not consider important factors such as the rock mass quality and the infrastructure vulnerability. New technologies such as slope meshing have been introduced in Canada but design methods are needed for specifying how these should be used.  The research objectives are to:

由于人口增长以及新的天然气、石油和采矿开发，未来十年加拿大将在陡峭的地形上修建数十亿美元的新基础设施，在陡峭的岩石斜坡和相关基础设施附近生活或工作的人们将面临地质灾害。该研究计划的长期目标是改进地质灾害评估技术，并建立地质灾害评估与设计适当的风险缓解措施之间缺失的联系，以减少与陡峭岩石斜坡上的岩石掉落相关的损失。​短期目标解决三项不足当前陡峭岩石斜坡的风险管理可能需要很长时间，并且可能使进行评估的岩土工程师面临不安全的现场工作，用于定义安全建设的区域；这些公式没有考虑岩体质量和基础设施脆弱性等重要因素，加拿大已经引入了斜坡网格划分等新技术，但需要设计方法来指定如何使用这些技术。研究目标是：
