“…Due to high precipitation rates, the area of Sfakia may be vulnerable to floods (presence of steep river basins and narrow gorges), as presented here and elsewhere [63]. Moreover, a potential increase in temperature due to climate variability may cause additional impacts on ecosystems functioning and overall water balance in the area.…”

“…At the same time, it is also very crucial to maintain the quality of landscape and preserve the underground and surface water resources [59]. These goals are challenged further by climate variability [60][61][62] and the mountainous terrain of the area [63], stressing further the biodiversity and the status water resources [64,65] and, subsequently, the economic development of the area (e.g., agricultural production) [66][67][68]. Finally, there are recorded chronic problems in water management, either regional or local scale, such as the legislation, bureaucracy and severe barriers in implementation of the existing water-management plans [56,69], which urgently need to be addressed [23].…”

Sfakia is a mountainous municipality located in the southwestern area of the island of Crete, including the southern part of the Lefka Ori mountain, with an elevation ranging from sea level to over 2400 m. The mountainous massif mainly consists of carbonate rocks and intense karstic phenomena can be observed. The part of the area exceeding over the elevation of 600 m is characterized by high amounts of precipitation (1500 mm). Despite this high precipitation, the water availability in the area is low. This work aims to identify the factors that affect the water-resources availability in this area. In addition, issues related to proper water management are presented and discussed that will allow areas with similar characteristics to adapt to climate change. Our study identified the complex geological setting of the area that redirects water away of the hydrological basin (karsts) and the geomorphology that favors precipitation loss through runoff as the most important factors for the low availability of water resources. This paper attempts to create a base of discussion for similar cases worldwide by providing a framework of approaching scientifically analogous problems.

“…Subsequently, we tried to evaluate the uncertainty that can be caused by different roughness values in real conditions. Ruman et al (2021) also faced a similar problem in their work. They proceeded by choosing a method of repeated modelling with 6 different values of the Manning roughness coefficient (differing by one hundredth) and then determining a range of peak flows at individual roughness values, which differed by up to 40% in total.…”

The geological environment is undoubtedly one of the basic factors that influence the formation of surface runoff. The extent to which this factor can also affect the hydrodynamic characteristics of flash floods, which is also indirectly associated with flood risk, is the main topic of this study. In two geologically different areas of the Bohemian Massif (crystalline rocks predominate) and the western Carpathians (flysch rocks predominate), a total of 40 watersheds characterised by sharing a certain hydrological analogy were selected (20 watersheds from the Massif and 20 from the Flysch zone). In each of these watersheds, 1-year, 10-year and 100-year flash flood return periods were constructed using the two-dimensional hydrodynamic model Iber. The outputs from this model included raster datasets of areas, depths, and flow velocities during inundations. Subsequently, these rasters were analysed and compared with an emphasis on differences within the individual geological study areas. The outputs showed clear differences in the individual hydrodynamic characteristics (e.g. the average inundation area during Q100 was 29.07% larger in the Flysch than in the Massif). Overall, the Flysch zone appeared to be far riskier in terms of flash floods than in the case of the Bohemian Massif.
