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).

In order to meet the projected water needs of Shandong Province in the future, the system dynamics model of water cycle system is designed. The system dynamics model of water cycle system consists of three sub-models: population growth model, water demand model and water supply model. We use the logistic growth model to forecast the population in population growth model, use the water price elasticity of water demand to show how water usage responds to price change, and analyze the desalinization rate and the purification rate of water to meet water supply. In addition, by using System Dynamics modeling software, various types of models for water cycle analysis can be simulated. The model output shows this effect clearly..
