Four concepts are defined for water resources systems: comprehensive management, integrated management, area horizons and time horizons. Five phases in development of water resources are: initial phase of modest demand (water transferred only in space), intense developmental phase (water transferred in both space and time), water transfer among the adjacent areas, water re-allocation phase, and the phase of developmental maturity. The comprehensive management incorporates the external social, economic, environmental, financial and political influences by specifying the goals to be attained. The concept of water resources supersystem, as a set of dependent systems, is introduced. The integrating management means incorporating a set of purposes as the internal aspects of resource management. They are realized by economic, social, environmental and other optimizations of the well defined objective functions. Objectives are fulfilled by matching supply and demand. Thus a triad of goals-purposes-objectives is defined. Three basic area horizons for a system are: the main system area, the adjacent physically-interacting area, and the surrounding areas interacting through water or power demand. Five time horizons of effects on systems are: period of economic life, period of physical life, horizon of obsolescence, period of full allocation of available water, and period during which significant climatic changes have occurred.

Abstract. Integrated Water Resources Management (IWRM) recommends, among other things, that the management of water resources systems be carried out at the lowest appropriate level in order to increase the transparency, acceptability and efficiency of the decision-making process. Empowering water users and stakeholders transforms the decision-making process by enlarging the number of point of views that must be considered as well as the set of rules through which decisions are taken. This paper investigates the impact of different group decision-making approaches on the operating policies of a water resource. To achieve this, the water resource allocation problem is formulated as an optimization problem which seeks to maximize the aggregated satisfaction of various water users corresponding to different approaches to collective choice, namely the utilitarian and the egalitarian ones. The optimal operating policies are then used in simulation and compared. The concepts are illustrated with a multipurpose reservoir in Chile. The analysis of simulation results reveals that if this reservoir were to be managed by its water users, both approaches to collective choice would yield significantly different operating policies. The paper concludes that the transfer of management to water users must be carefully implemented if a reasonable trade-off between equity and efficiency is to be achieved.

Abstract. With the increasing trend of water-related disasters such as floods and droughts resulting from climate change, the integrated management of water resources is gaining importance recently. Korea has worked towards preventing disasters caused by floods and droughts, managing water resources efficiently through the coordinated operation of river facilities such as dams, weirs, and agricultural reservoirs. This has been pursued to enable everyone to enjoy the benefits inherent to the utilization of water resources, by preserving functional rivers, improving their utility and reducing the degradation of water quality caused by floods and droughts. At the same time, coordinated activities are being conducted in multi-purpose dams, hydro-power dams, weirs, agricultural reservoirs and water use facilities (featuring a daily water intake of over 100 000 m3 day−1) with the purpose of monitoring the management of such facilities. This is being done to ensure the protection of public interest without acting as an obstacle to sound water management practices. During Flood Season, each facilities contain flood control capacity by limited operating level which determined by the Regulation Council in advance. Dam flood discharge decisions are approved through the flood forecasting and management of Flood Control Office due to minimize flood damage for both upstream and downstream. The operational plan is implemented through the council's predetermination while dry season for adequate quantity and distribution of water.

<div> <p>Once the human technology develops, the study of its influence over the environment, the soil, the water, the flora and the fauna is becoming increasingly important. In communism, due to the lack of integrated management of water resources, the quality of the waters in Romania has constantly worsened. In the same time, the quality of the waters of the Jiu River has worsened. After 1990, especially after Romania&#39;s EU accession, our country was obligated to pass a rigorous environmental control which also includes legislation according to the international norms. Our work aims to analyze if the integrated management of water resources is applied to the Jiu River course and also, aims to analyze the evolution of the concentration of heavy metals in Jiu River course in the coming years using a mathematical forecasting model.&nbsp;</p> </div> <p>&nbsp;</p>

Ecohydrology is an approach to integrated water resources management that offers a sustainable development approach in understanding the environment and water resources systems. In this case the conditions where clean water and food can be created to reduce the number of stunting in an area. The concept of ecohydrology can also prevent the spread of disease through water. The introduction of this concept is intended to reduce stunting and overcome the lack of clean water in the future. In this case the concept of Ecohydrology is offered with the existing water purification plan to produce clean water that is ready to use and utilizes materials that are easily available and have low prices. Keywords: Stunting, ecohydrology concept

Purpose – The purpose of this paper is to focus on the assessment of water resources in the Seybouse middle sub-basin. Analyses of water and various current uses are used to draw attention to the necessity of implementing water resources integrated management into a plan aiming at a rational exploitation. Design/methodology/approach – Any sustainable management of water resources is closely dependent on the ability to accurately assess the quantity and quality of available water resources that are used as water supply for the population, agricultural production, industrial or energy. The analyzed and processed available data serve as database for integrated water resources management. Findings – Analysis shows that the annual water supply is represented by 71 percent of the surface water resources and 29 percent of groundwater. The total volume of water used in the middle Seybouse basin is estimated at 36.22 hm3/yr. The predicted water needs are estimated to 79.19 hm3/yr in 2030. The groundwater of the Guelma alluvial aquifer exhibits a calcium chloride-facies general trend. The evolution of the chemical elements is related mainly to the geological nature of the reservoir lithologies. The heavy metals do not exhibit clear anomalies, but the surface water of the majority of streams is heavily infected with bacterial germs. Practical implications – The obtained results show that the Seybouse middle sub-basin needs twice as much water by 2030 for the different uses. This requires a better management of water resources for a sustainable development in this specific region of Eastern Algeria. Originality/value – This paper is devoted to the management of water resources in a specific region (the middle Seybouse basin) which constitutes an interesting example of considerations to be taken for a sustainable development.
