Integrated monitoring in small wooded catchments in Lithuania

Abstract

In the background monitoring areas (small wooded catchments) agricultural pollution is negligible and the atmosphere is the only source of widescale pollution. We review the chemical compositions in the soil profiles of Aukstaitija, Dzukija and Zemaitija  in Lithuania. We describe also trends in groundwater level fluctuations, the chemical composition of groundwater in 1994–1999, compare the chemical and physical properties of runoff water and show results of the simulation of successive data series of soil water flow and soil moisture saturation at different depths by the SOIL model. The simulation results may be used to evaluate water movement and element mobility  in the soil.
