Seasonal groundwater turnover in the north and south of Sweden
2007 (English)Conference paper, Presentation (Other academic)
Nutrient leakage from agricultural areas in Sweden mainly occurs during the autumn in the south and during the spring in the north. The infiltration of nutrients also reaches greater depths in the south. An occurring “seasonal groundwater turnover” similar to that in lakes is the suggested mechanism. This thermal convection results from changing temperatures (densities). The 10oC groundwater in southern Sweden becomes denser as it is cooled from the surface in the autumn, while the corresponding convection in the North occurs during the spring. Performed simulations show how seasonal temperature variations, under certain conditions, initiate and drive thermal convection.
