    The thesis presents a complex approach for modelling of a complex reservoir systems for water drainage management. The model has been built over a segment of a river with a certain parameters of water inflow, water outflow, required power production and max possible flood occurrence. Then the segments may be replicated with specific parameters to simulate whole system of the river. The model has been optimized in order to obtain the water drainage operation policy with regards of current and expected water volumes in the reservoirs ratio, required power production revenue, and minimal flood occurrence. Model has been verified on a walk-through basis on Valle D'Aosta river system and Volga-Kama river system. Flood propagation has been modelled in HEC-RAS software, while post-processing and impact analysis were performed in QGIS 3.0. The results show that proposed management approach allows to decrease the impact caused by inundation at Volga-Kama river basin by two times compared to the one implemented by the operator management approach. This result is achieved due to mitigation of the flood in highly populated areas and allowing additional water discharge among water management facilities in the areas with low population. Thus developed approach provides optimal water drainage for minimum flood occurrence and desired power production revenue

    What resources underpin the development of a territory? What does territorial management of resources mean? What specific characteristics and opportunities does territorial organization offer for agricultural production, regulation of sectors, and services? How are territorial public policies conceived and applied? But also, what are the limits of the territorial approach? How does a territorial approach refashion the frameworks of intervention for development? How do we implement and reinvent mechanisms to provide support, build skills, and promote production and good governance? How do we mobilize information systems, apprehend territorial dynamics, and encourage decentralized planning? Using a wide diversity of case studies, the book explores how actors, scales and scopes of intervention interact in the development of rural spaces in the countries of the Global South, both at the local level and in the global perspective of the objectives of sustainable development. The book brings together the experiences and views of more than 150 researchers and experts from CIRAD, AFD and their partners. It is aimed at researchers, engineers, professionals in the countries of the Global South, as well as students and the wider public

    Wadi Flash Floods

    Get PDF
    This open access book brings together research studies, developments, and application-related flash flood topics on wadi systems in arid regions. The major merit of this comprehensive book is its focus on research and technical papers as well as case study applications in different regions worldwide that cover many topics and answer several scientific questions. The book chapters comprehensively and significantly highlight different scientific research disciplines related to wadi flash floods, including climatology, hydrological models, new monitoring techniques, remote sensing techniques, field investigations, international collaboration projects, risk assessment and mitigation, sedimentation and sediment transport, and groundwater quality and quantity assessment and management. In this book, the contributing authors (engineers, researchers, and professionals) introduce their recent scientific findings to develop suitable, applicable, and innovative tools for forecasting, mitigation, and water management as well as society development under seven main research themes as follows: Part 1. Wadi Flash Flood Challenges and Strategies Part 2. Hydrometeorology and Climate Changes Part 3. Rainfall–Runoff Modeling and Approaches Part 4. Disaster Risk Reduction and Mitigation Part 5. Reservoir Sedimentation and Sediment Yield Part 6. Groundwater Management Part 7. Application and Case Studies The book includes selected high-quality papers from five series of the International Symposium on Flash Floods in Wadi Systems (ISFF) that were held in 2015, 2016, 2017, 2018, and 2020 in Japan, Egypt, Oman, Morocco, and Japan, respectively. These collections of chapters could provide valuable guidance and scientific content not only for academics, researchers, and students but also for decision-makers in the MENA region and worldwide

    Irrigation district sustainability

    Presented at Irrigation district sustainability - strategies to meet the challenges: USCID irrigation district specialty conference held on June 3-6, 2009 in Reno, Nevada.Fresno Irrigation District (FID) serves irrigation water to approximately 245,000 acres including the Cities of Fresno and Clovis, in California's Central San Joaquin Valley. As Clovis has developed they have looked for ways to diversify their water supply portfolio. Until recently, this mainly consisted of groundwater wells with some surface water supplies coming from FID. Clovis, in an effort to increase their dry year supplies, partnered with FID to develop the Waldron Banking Facilities. Through the agreement developed between Clovis and FID, Clovis provided half of the capital to develop the project in return for half of the project yield. Clovis also has the first right of refusal, on an annual basis, for any yield developed from the project. The Waldron Banking Facilities are comprised of three groundwater banking facilities located in the western portion of the District. In exchange for the banked supplies, FID then provides an equivalent amount of surface water to Clovis (in the eastern portion of FID). To develop a new water supply for the City and FID, during wet years and other times when surplus surface water supplies are available these supplies are routed to the groundwater recharge basins. In dry years, these banked supplies are then recovered from the aquifer, and delivered to FID growers. Two of the recharge basin sites were existing regulation basins, which were significantly expanded to add recharge capabilities. One of the sites is new, and placed at the bifurcation of one of FID's laterals. The recharge basin sites were strategically selected in order to provide an added benefit as regulation and storage basins that could be utilized during the irrigation season. The project was built over the course of three years, in phases. Now complete, the project includes approximately 250 acres of recharge basins, new measurement and control sites, seven recovery wells, and a network of monitoring wells. This paper will discuss the financial aspects of the project, project planning issues, design considerations, and how the twelve construction contracts were developed, managed and executed
