Abstract (in english)
   Comparison of the annual bulk precipitation in the Lesní potok experimental catchment (Central Bohemia, Czech Republic) in the hydrological year 2007 (758.8 mm) with the average annual value between the years 1995 and 2006 (737.4 mm) indicates almost similar values, whereas the stream water discharge in 2007 amounts to only 38.2% of the average annual value of the comparable time span. It has been found that the low discharge in 2007 resulted from the extremely temperate winter and from the anomalous distribution of the precipitation events throughout the year. These factors, together with higher pH values of stream water in 2007, reduced the output of elements from the catchment. The output of dissolved Al, Be, Cd, Mn, Ni, Pb, and Zn through the stream water in 2007 is amounted to only 15 to 20% of their annual output in 1995?2006. The unusually low output of the elements distinctly affected their budgets in the catchment changing towards more positive mass balance values.
