General Secretary Xi Jinping proposed to take water resources as the maximum rigid restriction, emphasize using water resources as its capacity permits, and actively explore new ways of high-quality development with regional characteristics. Yongkang is a water shortage county in the southern water-rich area. The contradiction between insufficient water supply and rapid economic and social development and continuous improvement of ecological environment is more prominent. In this paper, industrial water users are taken as the key control objects, and the added value of unit water consumption is taken as the rigid constraint index of water resources. It is incorporated into the reform of “heroes per acre” and integrated with the existing water resources management system to design the collaborative promotion mechanism framework of general rigid constraint of water resources. Then, the application practice in Yongkang is carried out, and the responsibilities of various administrative departments are clarified.

A major objective of the optimization of water resources allocation is to ensure the supply an adequate amount of water to users at the right time and maximize the utilization of water resources. However, in case of insufficient water supply, water shortage is likely to occur intensively for specific water users or in specific periods, referred to as a “concentrated water shortage”. The risk of a concentrated water shortage should be shared across a wider range of users and periods, so that it would have a less severe impact on each calculation unit in each period, which we refer to as the “wide-mild water shortage”. In this study, the nonlinear weight of the water supply objective function can be converted into a piecewise linear weight based on the law of diminishing marginal utility, making it possible to reduce or even eliminate the concentrated water shortage and thus making the allocation of water resources more reasonable. The case study in the Nen River basin in northeast China shows that the improved method results in a significant increase in water shortage units but a significant reduction in water shortage range. As a consequence, water shortage is more uniformly distributed from April to June, which contributes to solving the concentrated water shortage problem in May. However, it should be noted that to what extent the wide-mild water shortage can be realized depends not only on the marginal utility of water demand, but also on the available water supply and the regulative capacity of water supply projects. In spite of this, the improved method enables water to be supplied more suitably for users at the appropriate time, which contributes to improving the utilization of water resources and helping decision-makers better address the problem of concentrated water shortage.

RESUMO: O presente trabalho tem a proposta de avaliar a eficácia de duas metodologias de avaliação de risco de uma barragem no Nordeste Brasileiro no intervalo de 10 anos, baseando-se na inspeção e no nível de ameaça. Utiliza-se a metodologia Nível de Perigo da Barragem (NPB) para cálculo do nível de ameaça (Fontenelle, 2007) e para o cálculo do risco as metodologias da Companhia de Gestão dos Recursos Hídricos do Ceará (COGERH) e do Conselho Nacional de Recursos Hídricos (CNRH). Observa-se que o crescente número de barragens soma-se a preocupação com a segurança destas. Face a isto, utiliza-se a avaliação de risco como forma de priorizar ações de manutenção e recuperação. O estudo de caso ocorreu na Barragem Malcozinhado, localizada no município de Cascavel, no estado do Ceará. Com base na inspeção, calcula-se o nível de ameaça e o risco, compara-se estes com os resultados de 2006. Assim, observou-se o aumento no nível de ameaça, no entanto, o risco permaneceu, em geral, baixo, semelhante aos resultados de 2006. Este resultado se deve ao fato de que o número de anomalias aumentou, porém trata-se de uma barragem jovem, de pequeno porte e inspecionada regularmente.ABSTRACT: The present study has the proposal of evaluating the effectiveness of two methodologies of risk Assessment of a Brazilian Northeast dam in a range of 10 years, based on the inspection and the level of hazard. The methodology used for calculating the hazard level is the Dam Hazard Level (NPB). In addiction, in order to evaluate the risk is used the methodology of the Water Resources Management Company of Ceará (COGERH) and the methodology of National Resources Council Water (CNRH). The number of dams is increasing with to the concern for their safety. In view of this, risk assessment is used as a tool to prioritizing maintenance and recovery actions. The case study occurred in the Malcozinhado Dam, located in the municipality of Cascavel, in the state of Ceará. Based on the inspection, the level of hazard and risk is calculated, compared to the results for 2006. Thus, the increase in the level of hazard was observed, but the risk remained generally low, similar to 2006 result. This result is due to the fact that the number of anomalies has increased, but it is a young, small and regularly inspected dam.

Experience of the Central Asia countries in the sphere of reorming of institutional structures responsible for water resources management has been investigated. The outcomes of the works aimed at studying of the results of the integrated management principles application in order to improve structures and methods of water resources management are presented. These outputs enable to reveal special features of the approaches to the management problems solution in the conditions of available water resources abundance and lack in countries with different economic and natural/climatic conditions. The experience was summed up and the typical trends in the water sector management improvement accumulated in the Central Asia countries, as well as the date from other countries with the similar problems including NICs with centralized administrative systems, regions with the many-century traditions of irrigation farming, as well as the countries of transitional economy were revealed. Studying of many countries’ experience concerning adiption of the water resources integrated management allows us to state that there is no sungle ideal or universal model of transition from spatial/territorial management to basin management, no model which can be applied to any country. Analysis of the water resources management systems and institutions enables to formulate the main conditions for effective application of water resources integrated management principles. The paper notes that in spite of substantial progess in water resources management attained in the Central Asia countries many problems including practical application of water legislation, taking into account interest of all sectors of national economy, better coordination between ministeries and agencies involved in water resources management, participation of all stakeholders in taking decisions concerning water supply projects, distribution of juridical and financial obligations between water users and government, and insufficient coordination and agreement in actions at international, national andregional levels stay unsolved.

An inventory-theory-based inexact multistage stochastic programming (IB-IMSP) method is developed for planning water resources systems under uncertainty. The IB-IMSP is based on inexact multistage stochastic programming and inventory theory. The IB-IMSP cannot only effectively handle system uncertainties represented as probability density functions and discrete intervals but also efficiently reflect dynamic features of system conditions under different flow levels within a multistage context. Moreover, it can provide reasonable transferring schemes (i.e., the amount and batch of transferring as well as the corresponding transferring period) associated with various flow scenarios for solving water shortage problems. The applicability of the proposed IB-IMSP is demonstrated by a case study of planning water resources management. The solutions obtained are helpful for decision makers in not only identifying different transferring schemes when the promised water is not met, but also making decisions of water allocation associated with different economic objectives.

Abstract Integrated water resources management (IWRM) is being implemented all over the world, considering its wide area of applications and flexible spatial scale. Scientists have found IWRM useful in an Indian context also where a coordinated development of water and land resources is sought as part of complete economic, social and environmental welfare. The paper presents the concepts of ‘Local IWRM’ planning applied to water conservation and management in a case study of Ur river watershed in Tikamgarh district of Madhya Pradesh (India). The Plan considers effective utilization of land, water and other available natural resources, linked to the vulnerabilities and livelihood opportunities in the geographical area. The IWRM Plan, designed in three sections – (1) water management, (2) land management, and (3) livelihood management – provides specific suggestions on the activities under these three themes as useful inputs to the District Irrigation Plan (DIP) of the Government. The proposed IWRM Plan intends to promote the component of water demand management in district level planning and is envisioned to be an ‘implementable’ planning document for district level government. Acceptability of the IWRM plan is potentially enhanced as the plan was developed through a participatory process, wherein all relevant stakeholders were consulted at different stages of development.
