6. The role of subsoil properties for phosphorus leaching in agricultural soils
Sammanfattning : Phosphorus (P) leaching from agricultural land is a large contributor to eutrophication of many surface waters and the Baltic Sea. Better knowledge of P sorption and release in the subsoil could enable the development of effective mitigation strategies for P leaching. LÄS MER
7. Sustainable Arsenic Mitigation A Strategy for Scaling-up Safe Water Access : A Strategy for Scaling-up Safe Water Access
Sammanfattning : In rural Bangladesh, the drinking water supply is mostly dependent upon manually operated hand pumped tubewells, installed by the local community. The presence of natural arsenic (As) in groundwater and its wide scale occurrence has drastically reduced the safe water access across the country and put tens of millions of people under health risk.

8. Experiments with sand slurries pumped in 0.1 to 0.5 m diameter pipeline loops
Sammanfattning : The overall objective was to investigate the effectiveness of using high solids concentrations when transporting sand slurries in pipelines with centrifugal pumps. In detail, the aims are to present large-scale experimental pipe friction loss results and how head, efficiency and net suction head performance are influenced by the solid particles in large pumps and to compare friction loss data with a design model.

9. Seismic Investigations at the Ketzin CO2 Injection Site, Germany: Applications to Subsurface Feature Mapping and CO2 Seismic Response Modeling
Sammanfattning : 3D seismic data are widely used for many different purposes. Despite different objectives, a common goal in almost all 3D seismic programs is to attain better understanding of the subsurface features. LÄS MER
10. Stabilization-solidification of high water content dredged sediment : Strength, compressibility and durability evaluations
Sammanfattning : Dredging activities at ports and harbors are inevitable for safe navigation of ships and vessels. The outcomes of dredging are huge volumes of dredged materials, which can range from very fine and contaminated sediments to sands and gravels. The coarse sands and gravels can be directly used in civil engineering applications. LÄS MER
