“…As discussed by Arnaez et al (2004), roads often impede infiltration and also concentrate surface runoff with enough energy, resulting in occurring different erosion types. The results also are in line with the findings of Galia et al (2017) that splashing on the compacted roadbed and roadsides is unable to detach the particles but concentrated runoff can rapidly cause gullies in downstream sites, especially where culverts release water onto unprotected and steep slopes.…”

“…Changes in the SDS resulted from incorporation of small in size natural and man-origin incisions may contribute to erosion and fragmentation of the hillslopes (e.g., Luce and Wemple 2001;Kroczak et al 2015-review;Galia at al. 2017), delivery of the sediment material and its transportation to the river channel (e.g., Dietrich et al 1987;Batalla et al 1995;Froehlich and Słupik 1986;Froehlich and Walling 1997;Motha et al 2004;Croke et al 2005;Roy and Sahu 2017;Wemple et al 2017).…”

A surface drainage system (SDS) controls catchment hydrology and acts as an indicator of geomorphologic processes. In this study, a field-based and GIS-integrated approach enabling reconstruction of a surface drainage system, which operates during heavy rainfall in small flysch catchments, has been proposed. The reconstruction is based on the ALS-LIDAR data. The reconstruction of the SDS gave the opportunity for analysis of the changes between the river system and the SDS operating during heavy rainfalls. Results have revealed that the SDS operating during heavy rainfalls is several times better developed than the river system. The density has increased from c.a. 1.5 to 13.7 km·km − 2 . Moreover, the structure of the SDS has changed, what was confirmed by the parameters of the Hortonian type of the analyses. The most significant changes were related to the first-and second-order streams. These streams were, the most frequently, the man-origin incisions and natural-origin incisions/concavities on the hillslopes conditioned by micro-relief. The man-origin sub-system reached up to 35% of the SDS functioning during heavy rainfalls, whereas the sub-system composed of incisions/concavities conditioned by micro-relief reached up to 24% of this SDS. Smaller lateral valleys included to the SDS during heavy rainfalls constitute up to 37% of the SDS. The permanent streams constitute the remaining part of the SDS. Changes in the SDS have the influence on the drainage pattern, hydrological response of a catchment, and intensity of geomorphological processes; therefore, the changes in the SDS and their consequences have been discussed.

“…Among different types of roads, those that are unpaved or unsealed/unmetalled, tend to have the most significant contributions to sediment yield (Motha et al, 2004, Thomaz et al, 2014). In general, unpaved roads generate substantial amounts of sediment due to accelerated in situ erosion of unmetalled surfaces, destabilisation of side-cast material and the extension of the stream network and associated increased connectivity (Galia et al, 2017). Accordingly, much previous research has reported the importance of unpaved roads as major sediment sources in rural catchments (Bravo-Linares et al, 2017, Froehlich, 1995, Froehlich and Walling, 1992, Froehlich and Walling, 1997, Hoover, 1952, Ramos-Scharrón, 2018, Sheridan and Noske, 2007, Swift, 1984, Wemple et al, 2001, Ziegler and Giambelluca, 1997, Ziegler et al, 2000).…”
