The increased probability of occurrence of various hazards to water supply systems due to climate change requires the strengthening of their resilience through effective emergency preparedness planning. This paper introduces a method for the assessment of the resilience of water supply systems, including emergency supply measures. With 20 uniquely defined emergency situations, the technical constellations for possible impairments of the water supply are documented. The system analysis developed for each emergency situation is then used to determine and prioritise all suitable supply measures to reduce the supply deficit. Based on the data of a water utility close to Frankfurt, Germany, the developed system dynamics model was used to examine the resource utilisation for the respective emergency situations and to estimate the amount of water provided. The model allows us to scrutinize and compare emergency water supply measures as well as to identify required resources. Furthermore, the method helps us to prioritize measures as well as to make decisions when planning and providing emergency water supply (EWS).

会有足够的水吗?研究有效利用有限资源进行应急供水的系统动力学模型

气候变化给供水系统带来各种危害的可能性增加,这需要通过有效的应急准备计划来增强其适应能力。本文介绍了一种评估供水系统弹性的方法,包括应急供水措施。在20种独特定义的紧急情况下,记录了可能损害供水的技术星座。然后,针对每种紧急情况开发的系统分析将用于确定所有优先的供应措施并确定其优先级,以减少供应不足。根据靠近德国法兰克福的自来水公司的数据,所开发的系统动力学模型用于检查相应紧急情况下的资源利用情况,并估计所提供的水量。该模型使我们可以审查和比较紧急供水措施以及确定所需的资源。此外,该方法可帮助我们在计划和提供紧急供水(EWS)时确定措施的优先级并做出决策。
