Radioactive Seepage through Groundwater Flow from the Uranium Mines, Namibia
The study focused on the seepage of uranium from unlined tailing dams into the alluvial aquifer in the Gawib River floodplain in Namibia where the region solely relies on groundwater for its economic activities as a result of arid climatic condition. The study reviewed previous works besides water sample collection and analyses for major ions, metals and environmental isotopes in addition to fi...
متن کاملNumerical Simulation of Free Seepage Flow on Non-matching Grids
A new domain decomposition technique on non-matching grids for free boundary problems is considered. An iterative DD scheme is used to reduce the original free boundary problem to a sequence of problems on two sub-domains, one of which includes the free boundary and is described by a variational inequality and the other includes the remainder of the problem and is described by a second order pa...
متن کاملThe Gas Seepage and Migration Law of Mine Fire Zone under the Positive Pressure Ventilation
A fire developing tendency mathematical model of mine fire zone under positive pressure ventilation was established and was validated based on the particularly serious fire accident of Fuhua “9.20” in Heilongjiang province. Then the law of positive pressure ventilation influence on the fire zone developing tendency and its enlightenment to work safety were obtained. Under positive pressure vent...
متن کاملGranular flow in the marginal ice zone.
The region of sea ice near the edge of the sea ice pack is known as the marginal ice zone (MIZ), and its dynamics are complicated by ocean wave interaction with the ice cover, strong gradients in the atmosphere and ocean and variations in sea ice rheology. This paper focuses on the role of sea ice rheology in determining the dynamics of the MIZ. Here, sea ice is treated as a granular material w...
متن کاملSlipping zone location in squeeze flow
In squeeze flow rheometry, the main problem is the boundary condition between the squeezed material and the plates. So, the crucial assumption is to know the location and the shape of the sample part where wall slip may or may not occurs. This question is investigated from experimental results. For this, squeeze flow experiments are carried out to visualize the flow pattern at the walls. Influe...
