Eutrophication causes structural changes to the ecosystem of a water body such as increased production of algae and aquatic plants, depletion of fish species, and a general deterioration of water quality. We discuss the development of an Augmented Reality (AR) application (App) based on a generalised system dynamics model of chemical and biological processes involved in the development of algal blooms. The objective was to generate user-based decision-making scenarios that could be visualised in real-time ‘to see what cannot be seen in real life’, for agricultural and environmental management training. Visualisation of the modelled processes is an important part of enhancing learning outcomes. This was achieved by transposing the system dynamics (SD) model into C# and the game engine Unity for the development of a hands-on learning environment through an AR App called Affluent Effluent on the Microsoft platform ‘Hololens’. Conceptual and technological challenges and solutions associated with the App development are discussed, as is a brief evaluation.

富营养化会导致水体生态系统发生结构性变化，例如藻类和水生植物产量增加、鱼类数量减少以及水质普遍恶化。我们讨论了基于藻华发展所涉及的化学和生物过程的广义系统动力学模型的增强现实 (AR) 应用程序 (App) 的开发。目标是生成基于用户的决策场景，这些场景可以实时可视化“看到现实生活中看不到的东西”，用于农业和环境管理培训。建模过程的可视化是提高学习成果的重要部分。这是通过将系统动力学 (SD) 模型转换为 C# 和游戏引擎 Unity 来实现的，以便通过 Microsoft 平台“Hololens”上名为 Affluent Effluent 的 AR 应用程序开发动手学习环境。讨论了与应用程序开发相关的概念和技术挑战和解决方案，并进行了简要评估。
