Urban water system is the lifeblood of urban development and it has special effects in the urban landscape structure and function. In urban Planning and construction, water system should be carefully constructed under the water decides urban concept and the principles of overall coordination, ecological priority and local characteristics to realize the harmony of human and nature. The master plan of Dolon-nuur Town discusses the strategy of constructing urban water system in north winter city, and put forward to build perfect urban water structure, rich waterfront function, pay attention to flood control and detention, conform the monsoon, waterfront greening collocation, make full use of resources of ice and snow and avoid the pollution, in view of the cold city features.

The natural features and patterns of "Eight water Chang'an" is one of important symbols of the Tang Dynasty Culture,This paper discusses from the urban planning level the necessity of constructing the " Chang'an eight water" and its basic principles and methods, explores ways and means to achieve the objective from two levels of the long-term planning strategy and the gradual implementation.The paper propose in the course of restoration "Chang'an eight water" urban landscape basal, an overall planning must be developed from the perspective of urban water environment to change the linear metabolic pattern, and to construct the urban water system recirculating network.With the existing situation of urban water environment, trying to solve on-site problems of urban rain, sewage purification from the self-circulation. Considering the integrated relations among urban water catchment, water storage, water diversion projects and making them penetration with each other, from the point to surface progressively recovering the city "metabolic function" as a basic ecological node to improve the urban living environment.

The urban water system is a complex and dynamic for planning of an integrated framework. This paper illustrates Analytical Hierarchy Process (AHP) technique as a decision-making tool for the municipality’s urban water based on four different criteria i.e. economic, environmental, social, and sustainability to support stakeholders and water utility experts. Due to insufficient funds for the urban water planning, prioritization problems arise and for this hierarchical network represents with prioritization criterion to implement an alternative solution. Saaty’s analytical hierarchy process (AHP) hypothesis is explaining in the study with Multi-Criteria Decision Analysis (MCDA) and adoptable the alternatives through highest priority value. According to the AHP theory, all required criteria are ranking and preparing the list of alternatives to select the most prioritized solution to carry out in the plan of the urban water policy. Along with a consistency, a check of the final judgment is still carrying out by sensitivity evaluation of the synthesis model even if there are changes in decisions. The study find out the best workable solutions for existing issues in the urban water structure by promoting an interface between water users and stakeholders to reach a sustainable strategy in the city. AHP technique not only finds the important of each criterion but still comparing the criteria weights regarding objectives and alternatives. This application of AHP will ease the policymakers and stakeholders in the governing process for next-generation urban water system planning and designing by providing a framework and support to prepare a city master plan.

Abstract As one of the large ecological infrastructures, urban water system connectivity project is an important part of urban ecosystem construction. It has a variety of effects, such as conserving biodiversity, enriching urban landscape and increasing land value. It is helpful for the scientific planning and construction of the project to systematically evaluate the effects. However, due to the complex and various effects of urban water system connectivity project, there is no complete effect system and quantitative method. In this paper, the composition and mechanism of positive and negative effects of ecological economics of urban water system connectivity project were deeply analyzed to improve the composition system of eco-economic effects. At the same time, the emergy theory was used to put forward the quantification method of eco-economic effect system. Taking the urban water system connectivity project in Xuchang as an example, it’s ecological, social and economic effects were evaluated. The result showed that the average eco-economic effect of the project is 57.8 million dollars/year. Economic effect and ecological effect are significant, accounting for 88.83% and 9.77% of total effect, respectively. The former is mainly due to land value increment, and the latter is principally owing to biodiversity conservation. It showed that the water system connectivity project in Xuchang can promote the economic development of the surrounding areas and create a good ecological environment, which will bring huge eco-economic effect to the region.

When water utilities establish water loss control programs, they traditionally focus on apparent loss rather than real loss when considering economic feasibility in the water sector. There is an urgent need for new management approaches that can address complex relationships and ensure the sustainability of natural resources among different sectors. This study suggests a novel approach for water utilities to manage water losses from the water-energy (WE) Nexus perspective. The Nexus model uses system dynamics to simulate twelve scenarios with the differing status of water loss and energy intensities. This analysis identifies real loss as one of the main causes of resource waste and an essential factor from the Nexus perspective. It also demonstrates that the energy intensity of each process in the urban water system has a significant impact on resource use and transfer. The consumption and movement of resources can be quantified in each process involved in the urban water system to distinguish central and vulnerable processes. This study suggests that the Nexus approach can strongly contribute to quantifying the use and movement of resources between water and energy sectors and the strategic formulation of sustainable and systematic water loss management strategies from the Nexus perspective.

Optimizing the design and operation of an Urban Water System (UWS) faces significant challenges over its lifespan to account for the uncertainties of important stressors that arise from population growth rates, climate change factors, or shifting demand patterns. The analysis of a UWS’s performance across interdependent subsystems benefits from a multi-model approach where different designs are tested against a variety of metrics and in different times scales for each subsystem. In this work, we present a stress-testing framework for UWSs that assesses the system’s resilience, i.e., the degree to which a UWS continues to perform under progressively increasing disturbance (deviation from normal operating conditions). The framework is underpinned by a modeling chain that covers the entire water cycle, in a source-to-tap manner, coupling a water resources management model, a hydraulic water distribution model, and a water demand generation model. An additional stochastic simulation module enables the representation and modeling of uncertainty throughout the water cycle. We demonstrate the framework by “stress-testing” a synthetic UWS case study with an ensemble of scenarios whose parameters are stochastically changing within the UWS simulation timeframe and quantify the uncertainty in the estimation of the system’s resilience.
