21. Siltation and sedimentation problem in Mosul reservoir dam
Sammanfattning : 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. LÄS MER
22. Sedimentation and Its Challenge for Sustainability of Hydraulic Structures : A Case Study of Mosul Dam Pumping Station
Sammanfattning : 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. LÄS MER
23. Optimization methods for sedimentation and denitrification in activated sludge
Sammanfattning : Denitrification on readily biodegradable carbon compounds and separation of biological sludge from effluent water are examples of critical sub-processes for nitrogen removal in activated sludge. The aim of this thesis was to find operational strategies and newmethods to optimize these processes. LÄS MER
24. Numerical modelling of diapirism : influence of topography, sedimentation, erosion and viscoelastic-plastic rheologies
Sammanfattning : .... LÄS MER
25. Eulerian Numerical Study of the Sedimentation of Fibre Suspensions
Sammanfattning : Sedimenting suspensions exist in a varity of natural phenomena and industrial applications. It is already observed in experiments that the dilute fibre suspensions experience a hydrodynamics instability under gravity at low Reynolds numbers. Initially well-mixed suspensions become inhomogeneous and anisotropic due to this instability. LÄS MER
