Abstract Watershed of Dodokan in Lombok, Indonesia, is one of the strategic watersheds on the island of Lombok, and is a priority for rehabilitation of forest and land. This paper aims to analyse ecological water conditions in Dodokan watershed, Lombok, Indonesia, and recommends policy for improving the ecological conditions of the watershed. The results of this analysis are expected to be useful in implementing policies and programs to improve the ecological condition of this watershed, as well as to provide greater benefits for the communities around or related to this watershed. The watershed analysis focuses on five aspects, including flow regime coefficient, annual flow coefficient, sediment load, flood, and water use index. The results of the analysis show that the ecological condition of water management in the Dodokan watershed is poor, and can threaten the continuity of water resources in the Dodokan watershed. Therefore, rehabilitation activities are urgently needed.

Crete, located in the South Mediterranean Sea, is characterized by long coastal areas, varied terrain relief and geology, and great spatial and inter-annual variations in precipitation. Under average meteorological conditions, the island is water-sufficient (969 mm precipitation; theoretical water potential 3284 hm3; and total water use 610 hm3). Agriculture is by far the greatest user of water (78% of total water use), followed by domestic use (21%). Despite the high average water availability, water scarcity events commonly occur, particularly in the eastern-south part of the island, driven by local climatic conditions and seasonal or geographical mismatches between water availability and demand. Other critical issues in water management include the over-exploitation of groundwater, accounting for 93% of the water used in agriculture; low water use efficiencies in the farms; limited use of non-conventional water sources (effluent reuse); lack of modern frameworks of control and monitoring; and inadequate cooperation among stakeholders. These deficiencies impact adversely water use efficiency, deteriorate quality of water resources, increase competition for water and water pricing, and impair agriculture and environment. Moreover, the water-limited areas may display low adaptation potential to climate variability and face increased risks for the human-managed and natural ecosystems. The development of appropriate water governance frameworks that promote the development of integrated water management plans and allow concurrently flexibility to account for local differentiations in social-economic favors is urgently needed to achieve efficient water management and to improve the adaptation to the changing climatic conditions. Specific corrective actions may include use of alternative water sources (e.g., treated effluent and brackish water), implementation of efficient water use practices, re-formation of pricing policy, efficient control and monitoring, and investment in research and innovation to support the above actions. It is necessary to strengthen the links across stakeholders (e.g., farmers, enterprises, corporations, institutes, universities, agencies, and public authorities), along with an effective and updated governance framework to address the critical issues in water management, facilitate knowledge transfer, and promote the efficient use of non-conventional water resources.

The use of software agent systems and technologies to simulate water resources management scenarios and improve the engagement of stakeholders in policy making is gaining paramount importance. Such importance originates from two main concerns or change agents. Firstly, the context of water management is becoming highly complicated due to the intensity of connections with other systems, the diversity of stakeholders and the multiplicity (and sometime conflicting) objectives of decision partners. Moreover, the domain used for capitalizing on water management issues is becoming planetary (as it is the case of shared basins) rather than being local (watershed, watercourse, scheme, etc.). As a result, the concern is not limited to the optimization of the utility matrix of stakeholders but additional attention is required to incorporate many emerging issues such as the maintenance of financial sustainability, functional mainstreaming and improving engagement to promote reconciliation and change of water use behaviors. Secondly, the recent technological developments have improved the processing capacity of hardware, software functionalities and the accessibility of telecommunication platforms. Such developments have been reflected in the improvement of the capacities of decision makers to address complex problem domains. Software agents' technologies possess the qualities that make them useful for the provision of decision support in water management domains. As it is the case of irrigated agriculture, software agents' technology can be used for the design of farm surface irrigation systems, the improvement of irrigation systems management and the enhancement of the involvement of farmers in the processes of integrated water management. This paper is concerned with the use of agent based systems to facilitate the engagement of farmers in Al Ahsaa area in the management of water resources. The government of the Kingdom is adopting a demand management approach for the management of irrigation water by discouraging the cultivation of water-consuming crops such as wheat and dates. Improving the ability of farmers to analyze alternative cropping patterns significantly affects their water use behavior.

The advantages of the basin approach in the study of regional water use are justified in the article, water management areas according to the water management division of the Russian Federation were used as territorial units of the study. A universal methodic for the integrated assessment of the region’s water management activities was developed, based on geo/information technology. Stages of the study are described, including water management of the area, ranking based on the total anthropogenic load on water bodies and river basins, zoning of the territory to optimize the target use of water resources. The GIS of water use of the Lake Baikal basin is developed on the basis of governmental statistics, mass media examples of organization of water management data, as well as the results of automated mapping of water bodies. The results of water management regionalization are presented and spatial regularities of water use organization in the investigated territory are revealed. The ranking of river basins and water bodies according to the degree of anthropogenic load has been carried out, ecological problems of the region have been identified and their spatial localization has been fixed, the exact locations of pollution sources and their influence on water management have been established. Zoning of the territory under study for targeted use of water resources was proposed, five unique zones were identified, differentiated according to the special conditions for the formation of water resources and the specific use of water bodies, as well as the nature and intensity of the current and forecasted water use. A set of measures to optimize water use within the zones of targeted use of water resources is proposed.

For integrated water management in river basins in Ukraine, there is no toolkit for system modeling and selection of management structure in river basins according to environmental and economic criteria, which corresponds to the creation of water management systems under conditions of sustainable development. Therefore, the urgent task is to develop a system model of integrated water management on the example of the Ingulets River basin. The purpose of the work is to create a system model of integrated water resources management in Ingulets River basin, which provides scenario modeling of technological solutions, their evaluation and optimization of economic criteria for efficient water use under environmental constraints and criteria for achieving a good or excellent ecological status of the river basin. The system model is used as a toolkit, the method of decomposition of the river basin into subsystems, analysis of subsystems and their composition into a holistic model of integrated management by the basin principle. Telecommunication methods are proposed to improve monitoring. A method of scenario analysis is proposed, which performs simulation modeling of prospective management scenarios at the first level of the hierarchy, and at the second level - options are evaluated according to the criteria of cost-effective water use with environmental objectives and regulatory restrictions. For simulation modeling, a system of balance difference equations for the dynamics of water masses, mixing and spreading of pollution in rivers and reservoirs is formalized. A system of combined control for the impulse method of river washing was developed. Multicriteria optimization of variants of the control structure is carried out on the Pareto principle. A system model has been developed for integrated water resources management in the Ingulets River basin that meets the requirements of the EU Water Framework Directive on the establishment of cost-effective water use while ensuring good or excellent ecological status of rivers. The structural and functional diagram of the system model includes the subsystems: the water supply subsystem of the Dnipro-Ingulets canal; a subsystem for flushing the Ingulets River from the Karachunivske reservoir and displacing the saline prism into the Dnipro River; subsystem of environmental safety when discharging pollution into the river Ingulets; subsystem of water supply for irrigation in the Ingulets irrigation system, prevention of soil salinization. A system of technological, economic and environmental criteria for evaluating integrated management by the basin principle has been developed. They include maintaining the water level in reservoirs, displacement of salt water prism and limitation on water quality, ensuring the ecological condition of the river, and the dynamics of water resources consumption. Technological criteria determine the maintenance of water levels in reservoirs. Cost-effective water use is estimated on the basis of the dynamics of water consumption for river washing and irrigation. The formalized integrated management system in the Ingulets River basin includes operational water resources management and structure management. Integrated management is carried out according to subsystems, types of management and a system of criteria. For operational management the balance differential equations of water exchange in reservoirs are formalized. A two-layer model of water masses dynamics, pollutants distribution and mixing when flushing rivers from reservoirs is used. Scenario analysis is offered to select the optimal structure of the management system. Simulation scenarios are being simulated. Scenario optimization is performed on the Pareto principle. An example of evaluating the effectiveness of the proposed system and its comparison with the existing regulations for Ingulets River flushing is given.

Статья посвящена проблемам водных ресурсов и водопользованию в аридных районах на примере древнего и современного Израиля. При анализе истории водопользования обращается внимание и на рельеф и морфоструктуру территорий, определяющих месторасположение водоисточников и место развития древних городов. Большинство источников воды расположены вдоль зон линеаментов. Рассмотрены водные системы, приуроченные к Иорданской впадине, и, в частности, водные системы конца ханаанских времён (XIV–XIII вв. до н.э.) и начала древнего Израильского царства; эллинский период в истории создания водных систем; система водопользования в древнем Иерусалиме; искусственные водные системы конца старой эры (I в. до н.э.). Выдающиеся достижения инженерной и строительной практики древних израильтян в области водопользования опираются на их хорошее знание местных условий (в первую очередь особенности геологического строения) и умение при остром дефиците пресных вод собирать и сохранять её до следующих зимних дождей, бережно расходуя её в течение года. Опыт древних инженеров и поныне может служить достойным примером продуктивных отношений человека и природы. The article is devoted to problems of water resources and water use in arid regions at the example of ancient and modern Israel. When analyzing the history of water management also drew attention to the relief and morphological structure, defining the location of water sources and development of ancient cities. Most water sources are located along zones of lineament. Discussed the water system, dedicated to the Jordan basin, and in particular, the water system of the late Canaanite era (XIV–XIII centuries BC) and the beginning of the ancient Kingdom of Israel; the Hellenistic period in the history of the water systems; the system of water in ancient Jerusalem; artificial water system of the end of the old era (I century BC). Outstanding achievements of engineering and construction practices of the ancient Israelites in the area of water management based on their good knowledge of local conditions (primarily the features of the geological structure) and ability in acute shortage of fresh water to collect and keep it until the next winter rains, carefully spending it during the year. Experience ancient engineers today can serve as a worthy example of the productive relationship between man and nature.

The article focuses on the current topic of public water resources management. Globalization presents new challenges and demands for sustainable development for society. The current problem of modern humanity is the rational use of limited water resources. Water management is closely linked to the harmonization of social, economic and environmental requirements. The domestic water use system cannot meet European requirements for effective water supply due to moral and physical wear. An inadequate regulatory framework reduces the effectiveness of management processes and requires finding ways to attract investment to the industry, including in public-private cooperation. The analysis of the main problems of water management development, including non-compliance with European standards, moral and physical wear, lack of effective systems of water resources planning, monitoring and control of use of water resources, showed that these problems are primarily the result of an imperfect system of public water management. Based on commercialization processes, the water supply system through the implementation of public-private partnership mechanisms, provided that private entities are clearly monitored by public authorities, can produce significant socio-economic and environmental results. The research developed an algorithm for implementing an effective water management system at the state level by developing and implementing public-private partnership projects in accordance with the requirements of an effective water management system. The mathematical model of information and analytical support of processes of monitoring of rational water use in conditions of implementation of public-private partnership projects is defined.

Abstract. Drought is a function of both natural and human influences, but fully characterizing the interactions between human and natural influences on drought remains challenging. To better characterize parts of the drought feedback loop, this study combines hydrological and societal perspectives to characterize and quantify the potential for drought action. For the hydrological perspective, we examine historical groundwater data, from which we determine the decadal likelihoods of exceeding hydrologic thresholds relevant to different water uses. Stakeholder interviews yield data about how people rate the importance of water for different water uses. We combine these to quantify the Potential Drought Action Index (PDAI). The PDAI is demonstrated for a study site in south-central Oklahoma, where water availability is highly influenced by drought and management of water resources is contested by local stakeholders. For the hydrological perspective, we find that the historical decadal likelihood of exceedance for a moderate threshold associated with municipal supply has ranged widely: from 23 % to 75 %, which corresponds well with natural drought variability in the region. For the societal perspective, stakeholder interviews reveal that people value water differently for various uses. Combining this information into the PDAI illustrates that potential drought action increases as the hydrologic threshold is exceeded more often; this occurs as conditions get drier and when water use thresholds are more moderate. The PDAI also shows that for water uses where stakeholders have diverse views of importance, the PDAI will be diverse as well, and this is exacerbated under drier conditions. The variability in stakeholder views of importance is partially explained by stakeholders' cultural worldviews, pointing to some implications for managing water when drought risks threaten. We discuss how the results can be used to reduce potential disagreement among stakeholders and promote sustainable water management, which is particularly important for planning under increasing drought.
