This paper develops a decision support framework that assists managers in the urban water industry to analyse a mix of water service options, at the whole-of-city scale. The decision support framework moves decision-making in urban water systems from traditional command and control approaches that tend to focus on an outcome at a point in time to a more sustainable, inclusive and dynamic decision-making process driven by social learning and engagement. While available models and evaluation techniques provide valuable input to decision-making, the complex nature of urban water systems requires more than just social and economic criteria to be considered as part of decision support frameworks. The authors believe that current decision support frameworks need to be presented in a way that incorporates adaptive management and integrated urban water management strengths at the strategic and operational level. The inclusion of social learning and engagement is necessary to achieving this end.  相似文献

This paper presents the conceptualisation, design and implementation of an online course on the topic of Decision Support Systems in River Basin Management. The need for development of such a course has been recognised, as activities in the field of water resources planning and management increasingly depend on decision support methods such as simulation, optimisation and Multi Criteria Analysis (MCA). The online learning approach is particularly needed for continuous professional development and life-long learning of professionals active in this field, and especially for those coming from developing countries. The course was developed and implemented following the competence-based learning approach, supported by the EU FP 7 educational research project named TenCompetence, which also provided the learning platform for deploying and delivering the course. The paper presents the course design, implementation and evaluation by the course participants, with special focus on the course content and the developed learning resources. Participants’ evaluations show high appreciation for the course, but they also highlight areas for future improvements.  相似文献

Successful implementation of integrated water resources planning and management (IWRM) requires delineation of regions that are relatively homogeneous with respect to multiple criteria, including hydrographic, physical-environmental, socioeconomic, and political-administrative aspects. The water resources planning and management (WARPLAM) DSS is presented as tool for regionalization in support of IWRM through: (1) GIS processing of spatial data related to multiple criteria for defining the homogeneity of clustered base units (e.g., catchments) with respect to multiple criteria; (2) application of fuzzy set theory to development of composite measures of homogeneity over all criteria for alternative clustering of adjacent base units; and (3) development of a modified dynamic programming clustering algorithm that guarantees consistent optimal solutions based on user preferences on the relative importance of the suite of criteria considered for regionalization. The viability of WARPLAM DSS as a tool for regional delineation in support of IWRM is demonstrated through a case study application to the Tocantins-Araguaia River Basin, the second largest in Brazil.  相似文献

Climate change adaptation (CCA) has recently emerged as a new fundamental dimension to be considered in the planning and management of water resources. Because of the need to consider the already perceived changes in climate trends, variability and extremes, and their interactions with evolving social and ecological systems, water management is now facing new challenges. The research community is expected to contribute with innovative methods and tools to support to decision- and policy-makers. Decision Support Systems (DSSs), have a relatively long history in the water management sector. They are usually developed upon pre-existing hydrologic simulation models, providing interfaces for facilitated use beyond the limited group of model developers, and specific routines for decision making (e.g. optimization methods). In recent years, the traditional focus of DSS research has shifted away from the software component, towards the process of structuring problems and aiding decisions, thus including in particular robust methods for stakeholders’ participation. The paper analyses the scientific literature, identifies the main open issues, and proposes an innovative operational approach for the implementation of participatory planning and decision-making processes for CCA in the water domain.  相似文献

The Conchos basin is the largest tributary to the lower part of the Rio Grande/Rio Bravo basin. During recent years a severe drought has affected México’s ability to deliver water from the Conchos basin as required by the 1944 Treaty. In addition, it has generated not only economic problems in the USA and México but also political frictions between these two countries. The Mexican Conchos river has historically contributed with the highest amount of water to USA as established on the water treaty. A Decision Support System (DSS) was developed for the Conchos basin in order to gain a better understanding of the water resources management process in the basin, and to identify the alternatives to improve the cited process. The DSS is a semi-distributed model, based on System Dynamics, and developed using Powersim software. The DSS has been used to evaluate 25 long and short tem water resources allocation alternatives for the two main basin’s users: Irrigation Districts and Water Treaty. Some of the most important factors being tested on the 25 water management alternatives include National Commission of Water’s yearly water allocation policy, reservoir operation rules, improvement on water distribution efficiencies, etc. The DSS model shows that the historic water resources allocation implemented by the Federal government produces adequate results as compared with the other tested water management alternatives. However, for short term drought scenarios, it is showed that there could be other management alternatives that could perform better than the current water management allocation. In general, the DSS shows what we already expect of dynamic models of systems to provide that understanding the effects of multiple interacting variables in necessary to develop good natural resource management policies.  相似文献

Abstract

One challenging issue in flood planning and management is to design and apply integrated approaches to estimate likely future economic, social, and other human vulnerabilities to (and impacts of flood), and to identify desirable options that could be used to reduce these vulnerabilities. Given the uncertainties in flood management, it is difficult to decide which options are effective and desirable. Research on developing well-designed flood management strategies can provide the information and understanding necessary for identifying more effective options and better plans for ensuring regional sustainability. This paper focuses on methodology development for the multi-criteria evaluation of flood management options using the Great Lakes Basin as an example. It starts wivh an introduction of some major concerns about flood management in a context of watershed sustainability. This is followed by an indication of the importance of flood management option evaluation to sustainable water resource development. Then, it presents an integrated assessment (IA) approach to evaluate the performance of alternative flood management options, and to identify more effective and desirable policies. Application of the IA in the case study shows how the approach can be used for identifying the more desirable and effective options  相似文献

可持续的黄河水资源管理   总被引:1,自引:0,他引:1  
黄河是中华民族的母亲河,在中国经济社会可持续发展格局中具有重要的战略地位。随着工业化、城镇化的快速发展,黄河水资源供需矛盾日趋尖锐,开发利用程度已超过其承载能力,同时流域整体用水效率偏低、废污水排放量大,造成下游河道断流频繁,水污染日趋严重,水生态系统受到严重威胁。面对上述问题,黄河水利委员会通过开展黄河可供水量分配、实施水资源统一管理与调度、探索建立水权制度、推进节水型社会建设、强化水资源保护等一系列措施,保障多方取用水权,最大限度地满足了各方用水需求,使黄河水环境和生态功能得到改善。黄河实施水资源统一管理的探索和实践证明,对于资源型缺水的黄河流域而言,实施最严格的水资源管理制度是势在必然、当务之急。水资源管理与流域经济发展必须相互协调,应在顶层设计、制度建设、协调监督、管理能力建设等方面做好工作,以水资源的可持续利用支撑流域及相关地区经济社会的可持续发展。  相似文献

To manage water more effectively, a new approach is necessary, incorporating a balanced set of policies and in stitutional reforms. Its core is the adoption of a comprehensive framework for water management that recognizes the interactions among the elements of a river basin's ecosystem and incorporates cross-sectional and environmental considerations in the design of investments and policies. The new approach also calls for water to be treated as an economic good, for decentralized management and delivery stru ctures, greater reliance on pricing, and fuller participation by stakeholders.  相似文献

Natural variations in the global climate are governed by complex interactions among the atmosphere, oceans, and land cover. Modern climate models suggest that these variations will continue, but with larger magnitudes and greater variability due to human influences. This is expected to increase the risk of flood disaster events. To improve flood risk management, a flood decision support system architecture is proposed that capitalizes on the latest advances in remote sensing, geographic information systems, hydrologic models, numerical weather prediction, information technology, and decision theory. Specifically, the dynamic climate prediction system developed by the Institute of Atmospheric Physics, Chinese Academy of Sciences, is discussed in the context of flood management and planning in the Yangtze River valley, China.  相似文献
