is an arch centrepiece of the Multipurpose Project. It impounds the River Guadiana, on the border of Beja and Évora Districts in the south of Portugal. The takes its name from the town of its right bank. It creates a large reservoir with an inter-annual regulation capacity from which water may be distributed throughout the region.

This study investigates the potential impacts of climate change on water management within the Aral Sea basin. By analyzing a wide range of literature the study reviews the anticipated climate change and hydrological patens on water resources in the region. Providing an overview of the current situations and potential scenarios and solutions in the context of changing hydro-climatic ...

Managing transboundary river basins requires balancing tradeoffs of sustainable water use and coping with climate uncertainty. We demonstrate an integrated approach to exploring these issues ...

This review study investigated the response of low-inflow estuaries (LIEs) to releases as this type of estuary is particularly sensitive to freshwater inflow modification. LIEs occur in arid and semi-arid regions and are subject to periods of little to no freshwater inflow. Case were used to identify ecological health and societal benefits associated with flow releases. Successful ...

This result is in line with a number of regarding climate change impact on water temperature (e.g., Hari et al., 2006, Morrill et al., 2005), implying progressive heating of the river water. We also found that the strength of trends in water temperature relative to air temperature weakened for postdam periods ( Table 3 ), pointing to the role that these play in this regard.

Grand Ethiopian Renaissance (GERD) is located on the Blue Nile, as shown in Figure 1, which is a major tributary of the Nile River contributing up to 85% of its water, despite the fact that its contribution is seasonal (Hamada, 2017).The Blue Nile originates at Lake Tana in north-western Ethiopian Highlands and runs for approximately 1,450 km to meet another major tributary the White Nile.

Reservoirs and have complex , regional, and global connections with the environment and climate. construction and related hydropower development can trigger regional climate changes and significantly alter the availability of water resources. Simultaneously, climatic and changes alter water cycle characteristics, thereby affecting the design and operation ...

This has resulted in the downstream impacts of the being even worse than they could have been if the was being operated following an flow regiment, where water releases are managed to mimic pre- downstream hydrological conditions (Baird and Quastel 2015). people have a clear understanding of the various types of downstream impacts, those related to the ...

Water-based recreation and ecotourism at the were seen as the main vehicle for economic opportunities; it was envisaged that these would not only create employment but would also improve ...

irrigation project involves the largest reservoir in Europe and an irrigation network to cover 110000ha of land, with three main goals: water management, regional development and promotion of agriculture. This paper reviews the major impacts and assessment procedures of the project.

Research is needed to better understand how these complex interactions may develop over the coming decades and the associated social, political, and . Clearly, water issues will become even more important in the lives and activities of people [Cosgrove and Rijsberman, 2000; Grayman et al., 2012]. 1.1 Freshwater Stress

With , operating since 2002, the total volume of water retained in the Guadiana River and not reaching the estuary and coastal area is estimated to be 13,000 hm 3 year −1 (Dias et al., 2004). The resulting regulation of the freshwater discharge affects the frequency and style of the floods in the river basin.

Understanding and predicting the complex interactions between climate, hydrology, processes, water quality and biodiversity form the basis for a future sustainable management of Mediterranean systems and are important to: Study the climate Improve the representations of lakes in NWP models (improve weather

historical need for water storage in the Guadiana Basin led to the construction of a large scale creating a reservoir with capacity of 4,000 million m 3 and maximum flooded area of 25,000 ha. The is a large multi‐purpose project (irrigation, hydro‐electricity production, domestic supply, recreation) that answers to the old expectations of water storage in the dry ...

Analysis was based on a compilation of data on climate (temperature, precipitation, and drought index), water management (water depth and discharge volume and frequency), survey data on C ...

However, it is the beginning of the operation of the , in February 2002, that by doubling the volume of water already stored in the Guadiana River to approximately 8,000 hm 3, will be responsible for most changes in the downstream. The decrease in freshwater discharge and nutrient loading affects the primary productivity of the estuary and coastal zone (Sklar and ...

Abstract The paper impact of the Multi-Purpose Alentejo region (Portugal), focusing on tourism development. In 2002, the originated the largest artificial lake in Europe and was widely believed to bring a great number of benefits for the region by creating conditions for intensive irrigated farming and enhancing a new tourism destination in interior ...

In the past decade brought a tremendous landscape change in all three sectors-, social and economic. While the reservoir was a project which was carefully executed, there are certain issues which need to be monitored/rectified as the reservoir goes into 5th straight year with full capacity.

Our results reveal two responses to the implementation: 1) ... of a reservoir on the climate. normally assess the ... management of water resources, by ...
