“…The transport of pollutants in the river and related floods might impact ecosystems and endanger food production (Yang et al, 2015;Ouyang et al, 2017;Franqueville et al, 2018;Bento et al, 2019;Yang et al, 2019). The amount of water trasported in the river channel is also crucial for aquatic life and energy (Marquès et al, 2013).…”

Floods are recognized among Earth's most common and destructive natural hazards (Hirabayashi et al., 2013;Winsemius et al., 2015). A flood is defined as a large amount of water that overflows onto normally dry land (Merriam-Webster dictionary). Depending on the location and triggers of the flood occurrence, there is the distinction among coastal floods, flash floods and river floods (Berz et al., 2001;Jonkman, 2005;Kron, 2005). Coastal floods are usually led by strong tides and winds from the sea or big lakes, occasionally triggered by earthquakes in the ocean (Blöschl et al., 2015). Flash floods can be initiated by excessive rainfall, dam breach or glacier lake outburst that generally happens in relatively small areas (Hapuarachchi et al., 2011). A river flood, however, can involve multiple factors, occur in small or big catchments, and evolve more slowly than e.g. flash floods (Blöschl et al., 2015;Kron, 2005). This thesis focus on better understanding of typical river floods.Three types of factors influence flood occurrence: meteorological factors, biophysical factors and anthropogenic factors. Meteorological conditions might cause intensive rainfall, leading to surface runoff, which can be partially offset by evaporation depending on the temperature, wind and solar radiation conditions (Beven, 2012;Lindsey and Farnsworth, 1997;Nkemdirim, 1991). Biophysical factors, such as elevation, slope, vegetation and soil conditions will determine whether intensive rainfall and runoff will result in the development of a flood. Soil saturation and high intensity rainfall enhance runoff and flood development (Brocca et al., 2008;Chifflard et al., 2018;Saini et al., 2016). Channel formation of the flood plain and sedimentation-induced river bed elevation can also cause floodings Reisenbüchler et al., 2019;Wyzga, 2001). Anthropogenic factors like expansion of built-up areas and increasing arable land at the expense of nature reserves and forested areas impact the hydrological processes in watersheds distinctly, often increasing risks and frequency of floods at the end (
