| Zusammenfassung |
Vineyards are one of the eco-geomorphological systems most conditioned by
human activity in Germany. The vineyards of the Ruwer Valley (Germany) are
characterized by high soil erosion rates and rill problems on steep slopes
(between 23 and 26°) caused by the increasingly frequent heavy
rainfall events as well as deterioration due to incorrect land use
managements.
The objective of this paper is to determine and to quantify the hydrological
and erosive phenomena in one vineyard in Germany during different seasons
and under different management conditions (before, during and after
vintage).
For this purpose, a combined methodology was applied. Climatic (rainfall
depth distributions and return periods), pedological (soil analysis and
classification), geomorphological (sediment movements and rills evolution)
and biological (botanic marks on the vines) variables were used on the
two experimental plots in the village of Waldrach (Trier, region of
Rhineland-Palatinate).
The results showed high infiltration rates (near 100 %) and subsurface
flow which were detected by rainfall simulations performed at different
times of the year (between September and December). The highest variations
of the monitored rills (lateral and frontal movements) were noted before and
during vintage, when footsteps occurred concentrated during a short period
of time (between September and October). Finally, two maps of soil loss were
generated, indicated by botanic marks on the graft union of the vines. 62.5 t ha−1 yr−1 soil loss was registered in the experimental plots
of the new vineyards (2 years), while 3.4 t ha−1 yr−1 was recorded in the old
one (35 years). |
