Ice cascades in the Krkonoše Mountains
Švec, Matěj ; Engel, Zbyněk (advisor) ; Šťastná, Petra (referee)
The objective of this bachelor thesis is to obtain and present basic knowledge of the icefall on the Krkonoše Mountains. Localization has been made by field surveys in selected areas. Height was measured using a laser rangefinder. Criteria for icefalls was fixed at least 4 m height and 4 m wide. Values for the altitude, the inclination of the surrounding slopes, orientation and height difference on the surface were calculated using morphometric analysis in ArcGis. The values were compared and discussed with regard to the relief. Another objective was to make a research of recent publication about the icefall theme and make regional physical characteristics connected to the ice forms. The number of detected icefalls is 49. The biggest concentration is in glacial trough the Labské údolí valley (30). Another areas are in glacial trough the Obří důl valley, around glacial lakes- Wielki and Mały Staw (7) and in the Velká Kotelní jáma cirque (2). Icefalls are located between 904 and 1345 m above mean sea level (average 1172 m). The maximum height of the icefall is 100m (average 36 m). The height difference on the surface range from 583 m to 740 m (avarage 637 m). The inclination of the surrounding slopes ranged from 18ř to 39ř. Icefalls are located on east- facing sites with two branches east-northeast...

THE TECHNIQUE AND TACTICS OF SAFELY RUNNING VARIOUS WATERFALL TYPES ON KAYAK
Klaus, Jan ; Novotný, Petr (advisor) ; Bílý, Milan (referee)
Title: THE TECHNIQUE AND TACTICS OF SAFELY RUNNING VARIOUS WATERFALL TYPES ON KAYAK Purposes: The purpose of this thesis is to introduce the proper technique and tactics of running technical sections of rivers to intermediate and advanced kayakers, focusing especially on waterfalls and other river features with a significant vertical drop. The aim is to familiarize readers with this topic in a complex manner; to present them comprehensive information in order to have a better understanding of running technical sections of rivers on a kayak with an emphasis on safety and prevention of undesirable situations. Methods: This bachelor thesis is based on a literature review, and does not contain experimental suggestions. It is a qualitative research that has been tested and completed by the author and other active kayakers. The conclusions were made without any quantitative experiments or statistical analysis. This work was created by gathering relevant information from other professional and experienced sources and documenting it. Key words: Kayak, technique, tactic, kayak stroke, waterfall, water hole, slide, safety, whitewater, wildwater, boof, plugin, stomp

Characterisation of waterfalls in Krkonoše (Czechia) with the use of airborne laserscanning data
Hájek, Robert ; Lysák, Jakub (advisor) ; Janata, Přemysl (referee)
Characterisation of waterfalls in Krkonoše (Czechia) with the use of airborne laser scanning data Abstract This thesis deals with the possible use of airborne laser scanning data for the characterisation of waterfalls in Krkonoše Mountains. Data, which are used, was provided by The Krkonoše mountains national park administration. The objective of the thesis is a description of a new method how to locate the waterfall, measure its height, calculate basin area and create a longitudinal profile. The main research method is the analysis of the digital terrain model, derived from ALS data. The analysis is based on the use of ArcGIS 10.4.1 hydrological tools to detect the position of watercourses and to find optimal visualizations for locating crests and bases of the waterfalls. The characteristics of 28 selected waterfalls were obtained by using the proposed method. The end of the work presents the results and there are also discussed imperfections that were detected during application of the method. Keywords: airborne laser scanning, waterfall, Krkonoše
