Study Of Geo-Morphodynamic Processes In Cultivated Vineyards On Slopes In Ruwer Valley (Germany)

The present work pretends to examine the erosive soil response of vineyards on the high steeps in the Ruwer Valley (Germany) with different methods. The experiments were developed between September and December along three different land management situation of the soil: before, during and after vintage. Firstly, with geometrical rill monitoring we quantify the lateral (7 to 13 cm) and vertical (1 to 4 cm) erosion. The high variability on the hydro-geomorphological process along the steep slopes is confirmed by the soil transport. Elevated infiltration rates were noted using the runoff curve number and rainfall simulations; however, the final results were different. Finally, the negative impact of the erosion by anthropic activities was confirmed with two methods: RUSLE (Revised Universal Soil Loss Equation) and using botanic marks on the grape-vines. With the first techniques, 11.28 t ha(-1) and respectively with the second 3.4 t ha(-1) soil erosion rate was calculated.
