“…They found that the time lag of the sediment load is shorter than that of the discharge and that there is a strong linear correlation between them. A similar temporal dynamic was also found by Bezak et al [24], who made their conclusions based on diagrams' peaks.…”

“…Suspended sediment monitoring results in the study catchment also showed that the suspended sediment transport is more intensive during the rising limbs of the hydrographs [25]. Namely, the most important element of the suspended sediment transport is surface runoff formation and displacement of the sediment along the preferential surface runoff pathways [24].…”

Understanding the temporal variability of the nutrient transport from catchments is essential for planning nutrient loss reduction measures related to land use and climate change. Moreover, observations and analysis of nutrient dynamics in streams draining undisturbed catchments are known to represent a reference point by which human-influenced catchments can be compared. In this paper, temporal dynamics of nitrate-nitrogen (NO3-N) flux are investigated on an event basis by analysing observed lag times between data series. More specifically, we studied lag times between the centres of mass of six hydrological and biogeochemical variables, namely discharge, soil moisture at three depths, NO3-N flux, and the precipitation hyetograph centre of mass. Data obtained by high-frequency measurements (20 min time step) from 29 events were analysed. Linear regression and multiple linear regression (MLR) were used to identify relationships between lag times of the above-mentioned processes. We found that discharge lag time (LAGQ) and NO3-N flux lag time (LAGN) are highly correlated indicating similar temporal response to rainfall. Moreover, relatively high correlation between LAGN and soil moisture lag times was also detected. The MLR model showed that the most descriptive variable for both LAGN and LAGQ is amount of precipitation. For LAGN, the change of the soil moisture in the upper two layers was also significant, suggesting that the lag times indicate the primarily role of the forest soils as the main source of the NO3-N flux, whereas the precipitation amount and the runoff formation through the forest soils are the main controlling mechanisms.

“…A comparison of topographic changes and bedload transport has previously been suggested by using both sets of data (Lucia et al, 2013). A valuable attempt to study channel shape changes between events with DoDs and to relate them to field observations has recently been undertaken in the Italian Gadria and the Strimm basins (Cavalli et al, 2017) and in a steep forested torrent in Slovenia (Bezak et al, 2017). These studies differ from ours in that we isolate data for single events.…”

“…The effect of changing channel shape on sediment transport has been studied (e.g., Williams et al, 2015;Bezak et al, 2017). Seasonal patterns have been identified in other natural channels such as the Pasing-Potrero (Gran, 2012).…”

“…In the context of landslide protection "green infrastructure" is thus of high importance, i.e., the large-scale protective function of intact forest cover (Papathoma-Köhle and Glade, 2013Schmaltz et al, 2017Jaboyedoff et al, 2018. Protective forests can thus be seen as ecosystem-based solutions for disaster risk reduction (Eco-DRR), as many studies highlight the regulating function of forests on runoff (Beschta et al, 2000Wang et al, 2012 and slope stability (Bathurst et al, 2010Bezak et al, 2017Moos et al, 2016.…”

Climate change and disturbance regimes will alter the forest protective function against shallow landslides. • Climate change generally increased landslide risk in our simulations. • Only when future warming coincided with drying, the landslide risk decreased. • The adaptation of tree species to future climate change conditions has a direct effect on the stability of forested slopes. • Canopy disturbances reduce the risk of landslides, outweighing possible negative effects on the water cycle.
