Flux Fluxes in the Amphibolite Basin On the Green at the Marianske Lazne Water Works
 Krám, Pavel ; Veselovský, F. ; Čuřík, Jan ; Myška, Oldřich
The paper is about hydrology and hydrochemistry of the Na Zelenem catchment forested by spruce stands which growso n substrate formed by Cambisol on amphibolite. This catchment is characterized by fairly favorable hydrochemical conditions for terrestrial and aquatic biota. The catchment is able to effectivetely neutralize incoming acidic atmopheric deposition mainly due to chemical weathering reactions involving divalent base cations, calcium and magnesium. Mean average precipitation to the Na Zelenem catchment was 790 mm/yr based od 5 year studied period and mean surface runoff was 193 mm/yr in the last two years. Runoff was between 24 and 27% of annual precipitation input to the catchment in the last two years. The catchment accumulated less than 20% of total nitrogen input in bulk precipitation. About 36% of nitrogen left the catchment via surface runoff. About half of the nitrogen output was in the form of nitrate and about half in the form of dissolved organic nitrogen.
