“…The Black Forest catchments are relatively remote; long-range transport of air-pollutants is more important than emissions from local sources and the inputs are very similar to the levels measured in southern Scandinavia (Feger et al, 1990). Average SO 4 concentrations in streamwater (1988-1995/ 1996) were 75 (Schluchsee) and 115 (Villingen) µmol c SO 4 l 1 ; these levels are similar to those of the Norwegian streams Birkenes, Langtjern and Storgama (same time period) and are much lower than in streams of other low mountain ranges in Germany, e.g.…”

“…In general, four major processes can be responsible for S release from soil: (i) desorption of inorganic SO 4 , (ii) oxidation of reduced S species, (iii) excess mineralisation of organically bound S, and (iv) weathering of S-containing minerals. Feger et al (1990) and Mayer et al (1995) assumed that oxidation and weathering are negligible (max. 0.013 mmol c SO 4 m 2 yr 1 ; Prietzel, 1998b) in the two catchments.…”

“…Research in the catchments started in 1988 (Feger, 1993a) and deposition and stream chemistry data has been collected from 1988 until 1995 and 1996 at Villingen and Schluchsee, respectively. A detailed description of the catchments is given in Feger et al (1990), Feger (1993a, and Mayer et al (1995).…”

“…S pools and SO 4 dynamics of the Black Forest, Germany, catchments Schluchsee and Villingen (Table 1a) have been analysed by Feger et al (1990), Feger (1993a, Armbruster (1998) and Prietzel (1998a). These detailed data, the proximity of the catchments to each other (same deposition history), and their differences in soil S pools and S release make these catchments well-suited for this attempt to model the past and future concentrations of SO 4 in streamwater.…”

“…Feger et al (1990) suggested that mineralisation of the S org pool is the most likely SO 4 source at Schluchsee. Furthermore, a comparison of soil S pools (forest floor and 0-80 cm) with the cumulative SO 4 net release (19881995) showed that the release at Schluchsee cannot be explained by losses from the inorganic SO 4 pool (Alewell, 2001 …”

The sulphate (SO 4 ) released by mineralisation and desorption from soil can play an important role in determining concentrations of SO 4 in streams. The MAGIC model was calibrated for two catchments in the Black Forest, Germany (Schluchsee and Villingen) and SO 4 concentrations in the streams for the years 2016 and 2030 were predicted. Special emphasis was placed on the dynamics of soil sulphur (S) pools. At Schluchsee, 90% of soil S is stored in the organic S (S org ) pool, whereas at Villingen, 54% is in the inorganic (S inorg ) pool. The Villingen stream chemistry was modelled successfully by measured Langmuir isotherm parameters (LIPs) for S inorg . Schluchsee data could not be modelled satisfactorily using measured or freely adapted LIPs only, as the S inorg pool would have to be more than five times larger than what was measured. With 60.5 mmol c SO 4 m -2 yr -1 as internal soil source by mineralisation and the measured LIPs, stream data was modelled successfully. The modelling shows that in these two catchments pre-industrial concentrations of SO 4 in runoff can be reached in the next two decades if S deposition decreases as intended under currently agreed national and international legislation. S org is the most likely dominant source of SO 4 released at Schluchsee. Mineralization from the S org pool must be included when modelling SO 4 concentrations in the stream. As the dynamics and the controlling factors of S release by mineralisation are not yet clear, this process remains a source of uncertainty for predictions of SO 4 concentrations in streams. Future research should concentrate on dynamics of S mineralisation in the field, such that mathematical descriptions of long-term S-mineralisation can be incorporated into biogeochemical models.

Sulfur and nitrogen input±output budgets were estimated for ®ve forested Appalachian Plateau basins in Pennsylvania for the period October 1988 to March 1990. Wet and dry deposition inputs were determined on a weekly basis from data collected at atmospheric deposition monitoring stations located near the study sites. Stream export was estimated from intensively sampled stream chemistry and continuous discharge data collected on all ®ve basins. On four of the ®ve basins, deposited sulfur was essentially in balance with stream¯ow export of sulfur (92±120% exported) for the 1989 water year. The ®fth basin had net retention of deposited sulfur, with only 42% exported. All ®ve basins retained the vast majority of deposited nitrogen (only 3±18% exported). The fraction of atmospherically deposited sulfur exported in stream¯ow was greater by a mean factor of 14 versus nitrogen, implying that sulfur dominates base cation leaching processes on these non-carbonate-based catchments. Although basins in the study were relatively homogeneous in terms of topography, climate, geology and land use, local basin conditions caused signi®cant dierences in input±output budgets, pointing to the need for replicated basin studies in a region.
