RisUrSim是EUREKA框架下的欧洲研究项目，其总体目标是开发一种综合规划工具，以实现城市排水系统的成本效益管理。该项目财团由工业数学和水利工程研究所、市政排水工程以及一家保险公司组成。本文涉及欧洲标准en752的监管背景和更详细的方法来模拟城市洪水的需要。对城市排水系统中污水附加物引起的城市洪涝进行分析，提出了双重排水模型的必要性。基于地表流和管道流的水力路由程序，建立了详细的双排水仿真模型。在附加条件下，为了最准确地计算地面上的水位，作为进一步评估可能的损害成本的基础，特别考虑了地表和下水道水流之间的相互作用。从数据需求、模型验证和首次仿真结果等方面介绍了该模型在一个小型案例研究中的应用。
The European research project in the EUREKA framework, RisUrSim is presented with its overall objective to develop an integrated planning tool to allow cost effective management for urban drainage systems. The project consortium consisted of industrial mathematics and water engineering research institutes, municipal drainage works as well as an insurance company. The paper relates to the regulatory background of European Standard EN 752 and the need of a more detailed methodology to simulate urban flooding. The analysis of urban flooding caused by surcharged sewers in urban drainage systems leads to the necessity of a dual drainage modeling. A detailed dual drainage simulation model is described based upon hydraulic flow routing procedures for surface flow and pipe flow. Special consideration is given to the interaction between surface and sewer flow during surcharge conditions in order to most accurately compute water levels above ground as a basis for further assessments of possible damage costs. The model application is presented for a small case study in terms of data needs, model verification and first simulation results.
