Conditions and morphogenetic role of the 2018 and 2021 debris flows in Starorobociański Cirque, Western Tatra Mts.

63--73

In this study we used geomorphologic mapping, precipitation analysis and archival photomaps to study debris flows in the Starorobociański Cirque, which were renewed in 2018 and 2021. Debris flow in 2021 was most likely the largest single flow recorded in the Polish Western Tatras in the twenty first century. It reached a length of about 870 m and it covered an area of 0.62 to 0.65 ha. We set July 14, 2021, as the date of debris flow initiation and 52.1 mm·d−1 as its threshold value. This is one of the lowest values provided in the literature for such flows in the Western Tatra Mts. On the contrary, debris flow which occurred July 18, 2018 was linked to threshold value of 150.5 mm·d−1. On the basis of former debris flow occurrence as well as precipitation analysis we interpret the appearance of debris flow in 2021 as an effect of short and intense rainfall.

Geomorphologic effects of human impact across the Svydovets Massif in the Eastern Carpathians in Ukraine

Contemporary changes in the natural environment in many mountain areas, especially those occurring above the upper tree line, are related to tourism. The Svydovets Massif, located in the Eastern Carpathians in Ukraine, is a good example of an area that is currently experiencing intense degradation. The highest, NE part of this area is crisscrossed with numerous paths, tourist routes, and ski trails. The strong human impact the area experiences is occurring simultaneously with the activity of natural geomorphologic processes. The processes occur with the greatest intensity above the upper tree line. The development of the discussed area has been occurring gradually since the early 20th century. It started when the region belonged to Austria-Hungary, then Czechoslovakia, and subsequently the USSR. Now that it belongs to independent Ukraine the level of tourism-related development has sharply increased. Comparing it to other mountain areas, such as the Tatras, the Alps, or the Monts Dore Massif in France, the Svydovets Massif is being reshaped much more rapidly due to the damage caused by human impact.
