“…This pattern of parallel rills (Ludwig et al, 1995;Sánchez-Moreno et al, 2012) shows the degradation processes on the vineyards. Vandekerckhove et al (1998) observed that erosion rates are enhanced by incorrect land practices by vine growers, and they are especially high after heavy and concentrated rainfall events.…”

Abstract. 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).

“…Effect of land cover combination and soil moisture Changes in the type of land cover and land cover combinations can also change the hydrological structure (Ludwig et al 1995), influencing the biological and geomorphological pulse processes. Ludwig et al (2005) studied the interactivity of the mosaic of land cover and runoff erosion for land use in arid and semiarid areas and concluded that local water and sediment redistribution was due to the existing vegetation pattern.…”

Soil moisture pulses are a prerequisite for other land surface pulses at various spatiotemporal scales in arid and semi-arid areas. The temporal dynamics and profile variability of soil moisture in relation to land cover combinations were studied along five slopes transect on the Loess Plateau during the rainy season of 2011. Within the 3 months of the growing season coupled with the rainy season, all of the soil moisture was replenished in the area, proving that a type stability exists between different land cover soil moisture levels. Land cover combinations disturbed the trend determined by topography and increased soil moisture variability in space and time. The stability of soil moisture resulting from the dynamic processes could produce stable patterns on the slopes. The relationships between the mean soil moisture and vertical standard deviation (SD) and coefficient of variation (CV) were more complex, largely due to the fact that different land cover types had distinctive vertical patterns of soil moisture. The spatial SD of each layer had a positive correlation and the spatial CV exhibited a negative correlation with the increase in mean soil moisture. The soil moisture stability implies that sampling comparisons in this area can be conducted at different times to accurately compare different land use types.

“…The observed substrata were: Colluvial deposits (D), Coarse-grained tonalithic granodiorites (Gg), Compact microcristalline granites (Gm), Metamorphites, low metamorphic degree (M). Following a well tested methodology [2,8,9], length, width and depth of Gullies were measured. The channels were split up in uniform segments of variable length but characterised by approximately constant cross-sectional shape.…”

“…The average slope of the Gully bed along each segment was also measured. Channels volume was evaluated by multiplying the length of each segment by the average section [2,3,8,9]. Data analysis was mainly focused on: length-volume relationship, Gullies morphology and Gullies frequency, calculation of the topographical threshold.…”

Soil erosion is one of the main causes of desertification in the Mediterranean basin. Recently, the role of channelled erosion in sediment delivery has been underlined by several studies. Rheological studies of debris flows, which provide information on the properties of the mixture, are essential for improving prediction and designing mitigation for potential hazardous areas. The paper has two aims: describing a simplified experimental methodology, set up for studying the relationships between Gully erosion and land use, applied to an experimental hilly site threatened by desertification in Central Eastern Sardinia (Italy); showing a debris flow model, based on a dimensional analysis and calibrated with experimental data, to identify the causes for momentum transport in the process. The results show a very significant impact of agricultural activities on Gully intensity and density, while the debris flow model proves to be capable of satisfactory predictions of actual events.
