Transport of waste leakage in stratified formations
نویسنده
چکیده
Contaminant transport in a strongly heterogeneous stratified formation whose log hydraulic conductivity distribution has a variance greater than unity is investigated. Four kinds of waste leakage scenario are studied. They are: (1) continuous waste leakage from landfills; (2) temporal waste leakage from landfills; (3) continuous deepwell injection wastes; and (4) temporal deep-well injection wastes. Ensemble average concentrations and variances of concentration distributions are calculated for the four scenarios. The results in this paper show that when heterogeneity of a formation increases, transport in this formation differs significantly from the linear solutions which assume that the variances of log hydraulic conductivity are less than unity. q 1998 Elsevier Science Limited.

Assessment of Waste Production and Heavy Metal Emission from Energy Production Sector of Zahedan City
Background and purpose: Due to the lack of accurate statistics on the amount of waste generated in the energy production sector in Zahedan, before any planning, one should identify all waste producing centers associated with the energy sector and also the quantity and quality of their waste in Zahedan. Materials and methods: This research is a cross-sectional descriptive study. It examined the ...

The water supply networks have always been of significance to researchers as a hydraulic system of transferring and distributing water. The pressure gradient is the main reason of water transfer in networks, and in case of non-standard pressure increase, the undesirable phenomenon of leakage occurs in the network. Leakage in urban water distribution networks causes water waste and enormous fina...
متن کاملOn Leakage from the Near-surface Radioactive Waste Storage Facility
Maisiagala RADON type radioactive waste storage facility was commissioned in 1963 in a marshy, ecologically sensitive locality, where soluble radionuclides easily can penetrate and migrate with groundwater. To assure the requirements of radiation safety, the analysis of radionuclide leakage from the radioactive waste storage facility is performed continuously. H (tritium, T1/2=12.33 years) is o...
متن کاملModel Calculations and Assessment of the Importance of the Colloidal based Radionuclide Transport in a Waste Repository in Granite
Highly compacted bentonite buffers are planned to be used as engineered barriers in the near-field of nuclear waste repositories in crystalline formations. The erosion of these bentonite buffers at the boundary to the surrounding Excavation Disturbed Zone (EDZ) can be a source of colloids leading to a notable concentration of colloids in the EDZ water, which is high above the natural colloid co...
