物理含水层模型是水文教育的一种非常有效的教学工具，但它们具有固有的局限性，包括购买成本高，模型材料的静态配置，可视化水文地质现象所需的时间，以及随着时间的推移重置和清洁它们的努力。为了解决这些问题和其他限制，我们已经开发了一个交互式的计算机模拟的物理含水层模型称为ParFlow砂缸。在这个游戏化的界面中，用户在学习真实的水文概念的同时，使用熟悉的网络应用程序（如带有滑块和按钮的界面）运行模拟。我们的用户界面允许参与者深入水文世界，了解有关模型参数（例如水力传导率）的假设，对地下水含水层系统的输入（例如抽水率）做出决策，可视化输出（例如溪流流量、运输和饱和度），并探索影响气候变化等真实的环境系统的各种因素。ParFlow Sandtank已被用于各种教育环境，每年有超过9，000名用户，我们认为这种新兴的教育工具可以广泛用于教育环境，并且可以扩大规模，为学生和教育工作者提供更大的可访问性。在这里，我们介绍了ParFlow Sandtank的功能和工作流程，两个用例，以及为支持和增强ParFlow Sandtank的覆盖范围而开发的其他工具和自定义模板。
Physical aquifer models are a highly effective teaching tool for hydrology education, however they come with inherent limitations that include the high cost to purchase, the static configuration of the model materials, the time required to visualize hydrogeological phenomena, and the effort to reset and clean them over time. To address these and other limitations, we have developed an interactive computer simulation of a physical aquifer model called the ParFlow Sandtank. In this gamified interface, users run the simulation using a familiar web-app like interface with sliders and buttons while learning real hydrologic concepts. Our user interface allows participants to dive into the world of hydrology, understanding assumptions about model parameters such as hydraulic conductivity, making decisions about inputs to groundwater aquifer systems such as pumping rates, visualizing outputs such as stream flow, transport, and saturation, and exploring various factors that impact real environmental systems such as climate change. The ParFlow Sandtank has already been used in a variety of educational settings with more than 9,000 users per year, and we feel this emerging educational tool can be used broadly in educational environments and can be scaled-up to provide greater accessibility for students and educators. Here we present the capabilities and workflow of the ParFlow Sandtank, two use cases, and additional tools and custom templates that have been developed to support and enhance the reach of the ParFlow Sandtank.
