"The present study is carried out to evaluate water regime of the shallow hillslope soils. Overland flow and shallow saturated subsurface flow are two important components of the watershed response to intensive rainfall. The interaction between surface water, ground water and streamflow during a storm event is an important issue in the watershed hydrology. One of the possible approaches to study this relationship is based on monitoring the content of the stable oxygen isotope in water as one of the available natural tracers. We evaluate the transport of natural tracer in the variably saturated soil profile by means of a one-dimensional numerical model. Vegetation season 2007 was analyzed with respect to tensiometric data and tracer content in the suction cups. In overall, a good agreement with observed values was achieved. It is further hypothesized that even better correspondence with observations would be attained if preferential flow and transport is considered."@en . "P(GA205/06/0375), P(GA205/08/1174)" .
