  2. 1. Subsurface dams in water resource management : methods for assessment and location

    Author : Imran Ali Jamali; Bo Olofsson; Stephen Foster; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Subsurface dams; Groundwater; GIS; Regolith thickness; Groundwater; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Natural groundwater storage can be improved by constructing a subsurface barrier that is a subsurface dam, in order to capture the subsurface flows and raise the groundwater levels (GWLs) in the sediment layers. Subsurface dams are preferable to surface dams because of lower evaporation, higher functionality, lower cost of construction, lessened risk for contamination and the possibility of utilizing land over the dam.

  4. 2. Siltation and sedimentation problem in Mosul reservoir dam

    Author : Issa E. Issa; Ian Foster; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Iraq depends on the Rivers Tigris and Euphrates for its water resources. Recently the flow of these rivers decreased drastically. In view of this situation the true storage capacity of the dams are to be evaluated to ensure prudent water resources management strategies. READ MORE

  5. 3. Sedimentological and Hydrological Investigation of Mosul Dam Reservoir

    Author : Issa E Issa; Ian Foster; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Area-storage capacity curves; Area reduction method; Bathymetric survey; Losing storage capacity; Mosul dam; Reservoir bottom morphology; Reservoir sedimentation; Sediment trap efficiency; Useful life of dam; Soil Mechanics; Geoteknik;

    Abstract : Reservoir sedimentation is the main problem that directly affects the performance of dams due to the reduction in the storage capacity of their reservoirs. Monitoring the storage capacity of reservoirs is an important issue for the planners, designers and operators of the dams. READ MORE
