“…Soil erosion assessment is taking into consideration high dependencies and interactions between hydrogeomorphic processes and vegetation. Stoffel and Wilford (2012) highlighted the role of vegetation in the initiation of hydrogeomorphic processes and its impact on stream morphology.…”

Use of models in the research of soil erosion processes is at the moment a standard practice and models are necessary tool for better understanding of sediment production and runoff, although their interpretation is limited by large uncertainties, including model parameter uncertainties. In this research we studied the main ecological factors and anthropogenic influences in sediment yield on the Provala basin of Montenegro analyzing the relationships between the physical-geographical, geological, soil, land use, climate characteristics and soil erosion intensity. Real soil losses, G yr , were calculated on 7541 m 3 yr -1 , specific on 597 m 3 km -2 yr -1 . The value of Z coefficient was calculated on 0.482 what indicates that the river basin belongs to the 3 rd destruction category; erosion process is medium. There is a possibility for large flood waves to appear in the studied basin. The results presented in this paper can provide decision support for watershed managers about where the best conservation measures can be implemented effectively and at low cost in the studied area. The methods we used in this study can also be of interest in sediment modeling for other basins in the Region.

“…Individual working steps included drying and sanding of the samples, counting of tree rings and measuring ring widths. Subsequently, growth curves were cross-dated with local reference chronologies to correct faulty tree-ring series from disturbed samples and to separate natural variability (e.g., climate, insect breaks or damage caused by forest work) from growth disturbances (GD) induced by torrential processes Stoffel and Wilford, 2012). A reference chronology was built from 20 trees (2 cores per tree) growing within the study area but obviously not influenced by geomorphic processes.…”

Debris-flows are infrequent geomorphic phenomena that shape steep valleys and can represent a severe hazard for human settlements and infrastructure. In this study, a debris-flow event chronology has been derived at the regional scale within the Gesäuse National Park (Styria, Austria) using dendrogeomorphic techniques. Sediment sources and deposition areas were mapped by combined field investigation and aerial photography using an Unmanned Aerial Vehicle (UAV). Through the analysis of 384 trees, a total of 47 debris-flows occurring in 19 years between AD 1903 and 2008 were identified in five adjacent gullies. Our results highlight the local variability of debris-flow activity as a result of local thunderstorms and the variable availability of sediment sources.

“…Long-term records of flash flood activity are often missing in remote environments, which in turn prevent the study of their impacts as well as a rational analysis of their drivers and ultimately meteorological triggers. On forested slopes, trees growing next to mountain streams can be used as a biological proxy and thus provide valuable proxy records to define the spatio-temporal patterns of past process activity with sometimes up to seasonal accuracy (Ballesteros-Cánovas et al, 2015a;Stoffel and Wilford, 2012;Stoffel et al, 2005Stoffel et al, , 2010. Intense flash flood events often cause damage to multiple trees (Ballesteros-Cánovas et al, 2015a;Sigafoos, 1964), which will respond with different growth disturbances, hereafter referred to as GD (Shroder, 1978;Stoffel and Corona, 2014).…”

• Flash floods represent a regional natural hazard in Guadarrama range.• Dendrochronology allows fill the lack of systematic data in mountain environments.• Regional studies and quality samples allow reducing the number of collected samples.• We complement existing records with 8 events covering the last~200 years.• Forest management could limit the amount of proxy evidence of flash flood events. Flash floods are a common natural hazard in Mediterranean mountain environments and responsible for serious economic and human disasters. The study of flash flood dynamics and their triggers is a key issue; however, the retrieval of historical data is often limited in mountain regions as a result of short time series and the systematic lack of historical data. In this study, we attempt to overcome data deficiency by supplementing existing records with dendrogeomorphic techniques which were employed in seven mountain streams along the northern slopes of the Guadarrama Mountain range. Here we present results derived from the tree-ring analysis of 117 samples from 63 Pinus sylvestris L. trees injured by flash floods, to complement existing flash flood records covering the last~200 years and comment on their hydro-meteorological triggers. To understand the varying number of reconstructed flash flood events in each of the catchments, we also performed a comparative analysis of geomorphic catchment characteristics, land use evolution and forest management. Furthermore, we discuss the limitations of dendrogeomorphic techniques applied in managed forests. G R A P H I C A L A B S T R A C T a b s t r a c t a r t i c l e i n f o
