Erosion with the subsequent loss of soil and fertility is one urgent environmental problems worldwide. On grassland slopes from montane to alpine elevation zones European Alps, shallow erosion a widespread regionally increasing phenomenon. This group mechanical denudation processes includes landslides nival abrasion (i.e., by snow gliding avalanches), which are displacing patches vegetation, unconsolidated material. The resulting bare ground areas as well dislocated material susceptible...
In small Alpine catchments, floods are mostly triggered by surface runoff generation during convective heavy precipitation events. Their magnitude also depends on the antecedent soil moisture content, which was shown in several previous studies. This study aims at understanding (a) sites change their response to rainfall events with high intensity under very moist pre-conditions what extent and (b) site characteristics this on. Therefore, we conducted repeated simulation experiments (40-80...
Floods and debris flows in small Alpine torrent catchments (<10 km2) arise from a combination of critical antecedent system state conditions mostly convective precipitation events with high intensities. Thus, climate change may influence the magnitude–frequency relationship extreme twofold: by modification occurrence probabilities hydrological event characteristics. Three different altitudes Western Austria (Ruggbach, Brixenbach Längentalbach catchment) were investigated both field...
Pre-rain-event soil moisture (preSM) plays a crucial role when evaluating runoff formation during heavy rainfall. Using sprinkling experiments and numerical modeling, this study investigates the impact of preSM on at small hillslope scale (≤100 m2). Sprinkling were conducted three sites in Austrian Alps observed hydrological behavior was simulated by using model HILLFLOW. For each site, modeled with different scenarios, covering whole range between permanent wilting point saturation....
Structural properties of undisturbed soils are critical for water retention and the reduction peak flows after heavy rainfall events. Forest commonly show high infiltration rates that can be attributed to a organic content formation larger pores through biological activity. Though soil disturbances, especially compaction, due timber logging considered rare event, impacts may long lasting. The productive, often fine textured Alpine Flysch belt particularly susceptible posing challenge...
Abstract The Brixenbach valley is a small Alpine torrent catchment (9.2 km 2 , 820–1950 m a.s.l., 47.45°, 12.26°) in Tyrol, Austria. Intensive hydrological research the since more than 12 years, including hydrogeological survey, pedological and land use mapping, measurements of precipitation, runoff, soil moisture infiltration as well conduction rainfall simulations, has contributed to understand response catchment, its subcatchments specific sites. paper presents synthesis form runoff...
Temperate forests are a substantial sink for the greenhouse gases (GHG) methane (CH4), carbon dioxide (CO2) and soil emissions of nitrous oxide (N2O) low. However, most these managed with ground-based harvesting systems causing severe disturbance. Soil displacement compaction has long-term effect on microbial community structure alters respiration, CH4 uptake, nitrogen turnover. This significantly reduces ecosystem services extraction tracks landings. disturbance is particularly persistent...
Soil compaction in forests, often a result of logging activities, poses significant threat to soil functioning and ecosystem services. Root systems their symbiotic relationships with mycorrhizae are particularly affected. Given the vital role that sustainably managed forest ecosystems play for climate change resilience mitigation,&#160;understanding effects on belowground is critical. To address knowledge gaps interactions between compaction, root growth, mycorrhizal associations under...
<title>Abstract</title> The hydrological effect of forests on reducing surface runoff and therefore mitigating flood hazards is well recognized in theoretical concepts, however its quantification for practical applications remains a challenge. Changes the due to changes forest can be measured but hardly predicted, which makes it difficult assess impact disturbances management protections against hazards. Game browsing as problematic disturbance protection that protective gravitational long...
Abstract Heavy rain on snow often leads to disastrous damages in torrent watersheds. In January 1998 a project was started investigate “runoff and infiltration characteristics of different alpine soil/vegetation units under cover”. One aim determine the runoff rates from snow-covered, differently cultivated (pastures, dwarf-shrub stands, forests), especially conditions sparse cover frozen soil. Differences formation between artificially snowed skiing areas plots with natural were also...
