21. Water in roads: Flow paths and pollutant spread
Sammanfattning : For better road construction and maintenance while minimising damage to the environment and groundwater, it is essential to monitor and model hydrological impacts on roads and consider pollution of groundwater. Water content in unbound material in road layers changes continuously and water flow usually occurs along pathways that are the main corridors for pollutant spread to groundwater. LÄS MER
22. Heat and water flows in freezing and thawing soils : numerical modelling, laboratory and field observations
Sammanfattning : A laboratory study of infiltration rates into frozen and unfrozen fine sand, including temperature effects of both soil and infiltration water, is reported. The average infiltration rate varied from about 10.6 mm/min for unfrozen conditions, to about 1-2 mm/min for frozen conditions. LÄS MER

25. Oceanographic studies of the Baltic Sea with emphasis on sea ice and mixing processes
Sammanfattning : This thesis comprises of model estimates of the water and heat budgets, re-estimating of the budget of deep-water mixing energy, model studies of generation mechanisms for internal waves, sea ice dynamermics and finally sea ice monitoring. Common site for all the studies are the Baltic Sea. LÄS MER
