### Spatial Diversity of Catchment Susceptibility
The highest susceptibility was found in municipalities characterized by varied topography (Krasnobrod, Szczeprzeszyn, Zakrzew), but it is important to keep in mind the role of this factor in the assessment--several criteria result from the morphometry of the area. \begin{table}

Table 5: Values of subindices in catchments located in the studied municipalities. In Dzierzkowicz municipality, all studied catchments are located on the slopes of the Wyznica river valley. Moderately susceptible catchments (203) are the most numerous group, forming larger clusters in western and eastern parts of the municipality (Figure 5). Highly susceptible catchments (125) are located in the central, steeper part of valley. Glusk municipality is located in the northern, lower part of Lublin Upland; hence, catchments of moderate susceptibility (387) prevail. These are located on gently sloping river valleys in the central and eastern parts of the municipality. Low-susceptibility catchments (194) are located in the northwest and west of the municipality. In Krasnobrod municipality, moderately susceptible catchments are the most common (167) and are concentrated in the west. Most are located on moderate slopes. High-susceptibility catchments (108) are situated on steeper slopes, mainly in central and northeastern areas of the municipality. In Poniatowa, moderately susceptible catchments are the most numerous (209).
