1. Hydraulic Conductivity of Saturated Sand-Bentonite mixtures
Sammanfattning : The implementation of the EC directive concerning landfill liners and covers sets stricter technical and environmental requirements for landfill barriers. It is therefore essential to identify suitable materials that fulfil these requirements. LÄS MER
2. Climate and geographical influence on the performance of infiltration-based facilities for managing runoff – Temporal and spatial variability
Sammanfattning : Climate change is expected to lead to more intense and severe rainfall events in the future, significantly increasing the risk of urban flooding. This change, characterized by spatial and temporal shifts in precipitation patterns, presents a challenge to the capacity of existing urban drainage systems, which may lead to higher runoff volumes than they were initially designed to handle.

3. Transport Coefficients during Drying of Solids containing Multicomponent Mixtures
Sammanfattning : This study investigated the transport coefficients involved in mass and heat transfer during the drying of a porous solid partially saturated with multicomponent mixtures. It included the coefficients governing liquid transport through the solid, the matrix of multicomponent diffusion coefficients in the liquid phase, and the effective thermal conductivity. LÄS MER
4. Maturation of Clay Seals in Deep Bore Holes for Disposal of Radioactive waste : Theory and Experiments
Sammanfattning : KBS-3 and very deep borehole (VDH) concepts are two major types of long-term geologicaldisposal methods for high-level radioactive waste (HLW) isolating from the biosphere. TheKBS-3V concept for isolating the HLW at the depth of 400-500 m, is the officially proposedoption in Sweden and has been the subject of considerable research in the past few decades,while the VDH concept was considered as an option in the 1950s but later became discouragedbecause of insufficient experience in drilling technology.

5. Solid Waste Landfills in an Arid Environment : Site Selection and Design
Sammanfattning : Selecting landfill sites is considered a complicated task because its whole process is based upon several factors and restrictions. This study shows the present status of solid waste management, sources, collection personnel, machinery and equipment that are involved in the waste collection process, financing and financial management for the major cities of the Babylon Governorate in Iraq (Al-Hillah, Al-Qasim, Al-Mahawil, Al-Hashimiyah and Al-Musayiab).
