  2. 6. Sedimentation and Its Challenge for Sustainability of  Hydraulic Structures : A Case Study of Mosul Dam Pumping Station

    Author : Mohammad Ezz-Aldeen Mohammad; Sven Knutsson; Nadhir Al-Ansari; Jan Laue; Rafid Al Khaddar; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : A successful management and operation of water resources projects are essential to maintain their functions. Dams and reservoirs are one of the largest worldwide infrastructures. They serve one or more functions; reliable store and release of water for different purposes, hydropower generation and   flood and draught controls. READ MORE

  4. 7. Building a coherent hydro-climatic modelling framework for the data limited Kilombero Valley of Tanzania

    Author : Alexander Koutsouris; Steve W. Lyon; Jan Seibert; Mekonnen Gebremichael; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Precipitation; Recession analysis; End - member mixing analysis; EMMA; GLUE; HBV; down scaling; Quantile mapping; CFSR; CMORPH; CRU; GPCC; ERA - i; MERRA; TRMM; UDEL; Satellite; Reanalysis; Kilombero; Tanzania; Eastern Africa; Africa; Physical Geography; naturgeografi;

    Abstract : This thesis explores key aspects for synthesizing data across spatiotemporal scales relevant for water resources management in an Eastern Africa context. Specifically, the potential of large scale global precipitation datasets (GPDs) in data limited regions to overcome spatial and temporal data gaps is considered. READ MORE

  5. 8. Observational Uncertainties in Water-Resources Modelling in Central America : Methods for Uncertainty Estimation and Model Evaluation

    Author : Ida Westerberg; Sven Halldin; Jan Seibert; Lars-Christer Lundin; Chong-Yu Xu; Deliang Chen; Alberto Montanari; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Central America; Discharge; Flow-duration curve; Fuzzy regression; GLUE; Model evaluation; Non-stationarity; Observational uncertainty; Precipitation; Quality control; Rating curve; Regionalisation; Uncertainty estimation; Ungauged basins; Water resources; Avbördningskurva; Centralamerika; GLUE; icke-stationaritet; kvalitetskontroll; modellutvärdering; nederbörd; observationsosäkerheter; avrinningsområden utan vattenfö-ringsdata; oskarp regression; osäkerhetsuppskattning; regionalisering; varaktighetskurva; vattenföring; vattenresurser; Hydrology; Hydrologi; Hydrology; Hydrologi;

    Abstract : Knowledge about spatial and temporal variability of hydrological processes is central for sustainable water-resources management, and such knowledge is created from observational data. Hydrologic models are necessary for prediction for time periods and areas lacking data, but are affected by observational uncertainties. READ MORE

  6. 9. Hydrophysical processes governing brownification : A case study of Lake Bolmen, Sweden

    Author : Clemens Klante; Avdelningen för Teknisk vattenresurslära; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Natural organic matter NOM ; Hydrodynamics; Lake; Hydrology; Drinking water production; Ecosystem;

    Abstract : Access to water of good quality and quantity has become more challenging because of a changing climate, as well as an increase in the use of natural resources, which has lead to altered water chemistry. One of these changes is known as brownification, resulting from a higher organic matter content causing a yellow-brown color of surface waters. READ MORE

  7. 10. Climate Change Effects on Rainfall and Management of Urban Flooding

    Author : Arun Rana; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Climate Change; Extreme Events; Intensive Rainfall; Urban Drainage; Intensity-Duration-Frequency; Statistical analysis; Flood Management;

    Abstract : Flooding in urban basins is intensifying due to increasing urbanization and climate change and variability. This thesis presents how the effects of climate change and high-intensive rainfall on the urban drainage system and management of flooding in urban areas of were studied in Mumbai, India and Southern Sweden, including Skåne and Gothenburg.
