Water is often used for a variety of conflicting purposes. Furthermore, as water is a dynamic resource, its equitable allocation across boundaries often poses problems for involved stakeholders. Integrated water resource management (IWRM) aims to promote the coordinated management of water across all boundaries. In theory IWRM is an effective solution to address multiple conflicting uses: however, in practice it is difficult to implement. This paper presents a case-study of an IWRM initiative in which the key component of participatory modelling is played out. Other important processes are integrated as well, such as problem structuring, social learning, and stakeholder engagement. In 2016-2017, approximately 30 stakeholders representing industry, municipalities, environmental NGOs, and federal/provincial government collaborated in order to explore opportunities to achieve sustainable watershed management in the Athabasca River Basin, Alberta Canada. Stress scenarios (including potential changes in climate, land use, and water use) were developed and used to test a series of water management strategies throughout the basin. These strategies were simulated within an integrated modelling tool in a live setting. Through this interactive process, promising strategies for sustainable water management were explored, and a series of recommendations for policy makers were identified. Recommendations include, but are not limited to, identifying areas for land conservation and reclamation priority, establishing in-stream flow need targets, and reducing water navigation limitations in the lower basin. Outlined through this paper, this case-study shows that examples of real-world participatory modelling efforts are in fact possible.

水经常用于各种冲突的目的。此外，由于水是一种动态资源，因此跨界的公平分配常常给参与的利益相关者带来问题。综合水资源管理（IWRM）旨在促进跨越所有边界的水的协调管理。从理论上讲，IWRM是解决多种冲突用途的有效解决方案：但是，在实践中很难实现。本文介绍了IWRM计划的案例研究，其中发挥了参与式建模的关键组成部分。其他重要流程也已集成，例如问题结构，社会学习和利益相关方参与。在2016-2017年，大约30个利益相关者，代表行业，市政当局，环保非政府组织，与联邦/省政府合作，以探索在加拿大艾伯塔省阿萨巴斯卡河流域实现可持续流域管理的机会。制定了压力情景（包括气候，土地利用和用水的潜在变化），并用于测试整个流域的一系列水资源管理策略。这些策略是在实时环境中的集成建模工具中进行仿真的。通过这一互动过程，探索了可持续水管理的有希望的战略，并为政策制定者提出了一系列建议。建议包括但不限于确定优先保护土地和开垦土地的区域，确定河内流量需求目标以及减少下流域的水域航行限制。通过本文概述，
