To study water and solute movement in a stony sloping (35%) soil, two tracers were applied to a Rendoll soil under a beech forest. From May to November, the movement of the tracers (Cl- and Br-) induced by natural rainfall was monitored by soil water sampling. Although the soil water transported the tracers mainly vertically, part of them flowed parallel to the soil surface within the topmost 15 cm. At the end of the experiment, the peak concentrations reached depths between 65 and 105 cm. These values, together with the measured mean water content, showed that about 40% of the throughfall was evaporated by the understory vegetation.
