Rapid urbanization, as observed in many regions of the world, poses special challenges, among them the diminution of flood risks and the protection against flash flood hazards. In order to evaluate flood risks, it is eligible to construct flood maps and necessary to update them regularly. For such purpose, advanced flood simulation tools are available that deliver accurate results in a short time with high-resolution information and advanced capabilities to model hydrodynamic processes. The hydrodynamic model 3Di is served from a GIS environment. This enables users to construct flash flood scenarios and run them in a cloud environment. A case study is presented for a district of the city of Muscat, Sultanate of Oman. The site is characterized by rapid urbanization, which thus requires an a priori use of a flood simulation tool and the option for a regular update.

正如世界许多地区所观察到的那样，快速的城市化带来了特殊的挑战，其中包括洪水风险的减少和山洪灾害的防护。为了评估洪水风险，有资格构造洪水地图，并且有必要定期对其进行更新。为此，可以使用高级洪水模拟工具，这些工具可以在短时间内提供准确的结果，并具有高分辨率信息和对流体动力学过程进行建模的高级功能。流体动力学模型3Di由GIS环境提供。这使用户能够构建Flash Flood场景并在云环境中运行它们。提出了针对阿曼苏丹国马斯喀特市区的案例研究。该地区的特点是快速的城市化进程，
