### Spatial Diversity of Catchment Susceptibility
These catchments are located in central and eastern parts of the municipality. There are also many catchments with low susceptibility (202) dispersed across the region. In Szczebrzeszyn municipality, most of the catchments are located on the slopes of the Wieprz valley. Moderately susceptible catchments (359) are the most numerous, and these are chiefly found in the central area. High-susceptibility catchments (161) are concentrated on the left side of the Wieprz. In this municipality, very highly susceptible catchments also occur (12). They occupy small areas on the strongly dissected slope to the left of the Wieprz river valley. In Trzydnik Duzy municipality, two big groups of catchments prevail: moderately (300) and highly (124) susceptible. They occur mainly on the slopes of the Karasiowka river valley (eastern part) and in the northwest (Figure 5). Very highly susceptible small catchments (16) occur in upper parts of the Karasiowka and Tuczyn valleys. In Urzedow municipality, susceptible catchments are located on the slopes of the Urzedowka and Podlipie river valleys. \begin{table}

Table 7: The number of catchments in municipalities by class of flash flood susceptibility (susceptibility classes according to Table 3). Moderately susceptible catchments (302) are the most common. These are located in the central area of the municipality. Highly susceptible catchments (102) are located mainly in the lower part of the Urzedowka valley. Wolka municipality is located in the northern, lower part of Lublin Upland. Moderately susceptible catchments are the most common (207), located in the municipality's central part, followed by low-susceptibility catchments (165). In Zakrzew municipality, moderately susceptible catchments prevail (241). They are located in the central and western parts. The second most common group is the high-susceptibility catchments (81), which mainly occur in the east. The greatest number of very highly susceptible catchments occur in this municipality (19). Zamosc municipality is located in an extensive depression, which is reflected in the distribution of susceptibility. The most dominant type is moderate susceptibility (604), which occurs throughout the municipality.
