Deterministic watershed models are often used to estimate the probable maximum flood (PMF). An approach for investigating the uncertainty in extreme flood modeling is proposed. Using different calibration objectives, several automatic calibrations of the University of British Columbia Watershed Model (UBCWM) are conducted and the resulting collection of optimal combinations of parameter values are used to simulate the extreme event. An application to the Coquitlam River watershed above Coquitlam Dam in southwestern British Columbia shows that the variability amongst the PMF estimates is relatively small in comparison with the potential uncertainties in estimating extreme events, with coefficient of variation values for peak flow, event volume, and time to peak of 4%, 1%, and 1%, respectively. The PMF-based simulations

Purpose – Universities can provide a leadership role to develop and mobilize knowledge to meet societal needs. In fulfilling this mission, universities can also serve as agents of sustainable development on campus and in communities they serve. The purpose of this article is to describe the drivers that have advanced the University of British Columbia Okanagan campus' operational and academic sustainability objectives; the initiatives and partnerships developed on campus and in the community in response to these drivers; and the outcomes and lessons learned. Design/methodology/approach – This article summarizes the experience of the University of British Columbia Okanagan campus in leveraging key drivers to develop sustainability initiatives and partnerships for greater operational efficiencies, cost savings, environmental stewardship and applied research. The university's leadership commitment to sustainability, economic opportunities and provincial legislative requirements are among the drivers discussed. This paper also provides an innovative partnership framework to support sustainable community development. Findings – Drivers of sustainability in higher education can contribute to the development of sustainability initiatives and partnerships that benefit institutions and communities and achieve operational and academic sustainability mandates. Practical implications – This article provides information that can be applied by institutions of higher education to advance sustainability within the context of current economic conditions and societal needs. Originality/value – The experience of the campus and the partnership framework presented in this paper is original. The framework provides a mechanism to engage students, faculty and the community in sustainable community development research. Key insights from multiple perspectives and lessons learned are shared.
