This article presents a novel installation for the development of hybrid physical-numerical flood models in an augmented reality environment. This installation extends the concept introduced by the well-known Augmented Reality-SandBox (AR-Sandbox) module, which presents a more educational, and less research-based and professional application. It consists of a physical scale topography built in a sandbox into which other elements (such as buildings, roads or dikes) can be incorporated. A scanner generates, in real time, a Digital Terrain Model (DTM) from the sandbox topography, which serves as a basis for the simulation of overland flow using professional hydraulic software (Iber+). The hydraulic and hydrological parameters (surface roughness, inlet discharges, boundary conditions) are entered with a simple Graphical User Interface (GUI) developed specifically for this project, as indeed was the entire system that allows the visualization of the simulation results. This allows us to obtain quantitative results of flood extension and magnitude, which are represented directly over the physical topography, yielding a realistic visual effect. This installation is conceived for both educational and professional uses. An example of its use is presented, through which its accuracy can be appreciated, and which also illustrates its potential.

运行混合物理-数值洪水模型的增强现实设施

本文介绍了一种用于在增强现实环境中开发混合物理-数值洪水模型的新装置。该装置扩展了著名的增强现实沙盒 (AR-沙盒) 模块引入的概念，该模块提供了更具教育性、更少基于研究和专业的应用程序。它由一个建立在沙箱中的物理比例地形组成，其他元素（如建筑物、道路或堤防）可以合并到其中。扫描仪根据沙箱地形实时生成数字地形模型 (DTM)，作为使用专业水力软件 (Iber+) 模拟地表流的基础。水力和水文参数（表面粗糙度、入口流量、边界条件）是通过一个专门为该项目开发的简单图形用户界面 (GUI) 输入的，实际上整个系统允许模拟结果的可视化。这使我们能够获得洪水扩展和大小的定量结果，这些结果直接在物理地形上表示，产生逼真的视觉效果。该装置设计用于教育和专业用途。提供了一个使用示例，通过该示例可以了解其准确性，并说明其潜力。产生逼真的视觉效果。该装置设计用于教育和专业用途。提供了一个使用示例，通过该示例可以了解其准确性，并说明其潜力。产生逼真的视觉效果。该装置设计用于教育和专业用途。提供了一个使用示例，通过该示例可以了解其准确性，并说明其潜力。
