Geomorphological settings and tufas and travertine location inventarisation in the east part of the Slovak karst

Tufas and travertine sedimentation is the main expression of young processes on the karst surface. There were published a few researches in the Slovakia mainly in the context of water chemistry and palynologi-cal research. We focused on the inventarisation of the know and new localities in the eastern part of the Slovenský kras Karst in this article. We are presenting 14 localities in the Háj, Miglinc, Šugov, Teplica, Zádiel and Baksov valleys with the presence of the slope and valley tufas accumulations that we catego-rized after morphological type, structural type, locality etc. The most of the springs/tufa depositions are situated on the observed or inferred faults of the N-S and W-E directions. The most occurring are slope formations with the occurrence of small barriers, dams and pools on the slope with the inclination higher than 20°. Higher inclination is one of the important geomorphological settings for tufas deposition be-cause of the CO2 leakage from the water. Other important setting is the occurrence of some roughness (leaves, roots, debris etc.). The most of inventarised locations were never described as tufa depositions. Geomorphological mapping results is inventory of the locations, geomorphological settings overview, longitudinal geomorphological profiles and photo documentation.
Key Words: tufa sedimentation, mix corrosion, Slovak karst, Ca2+ content, tufas microfoms, karst springs
History, present and charakteristics of radar satellite interferometry InSAR – as a perspective monitoring method of slope deformations
Geomorphologia Slovaca et Bohemica, 17, 2017, 1, 22 - 42.
12 figs., 1 tab., 97 refs.
The aim of this work is to present the method of satellite radar interferometry (InSAR) as a method suita-ble for monitoring slope deformations. At present, we are confronted with a number of scientific works in foreign literature on the subject but in the Slovak scientific community there has been a significant amount of scientific work. In the paper we describe the problem of slope deformations and various current and perspective monitoring methods. The core focus of the work is the historical development and contempo-rary state of the art, characteristics and the principle of radar satellite interferometry. The persistent scat-terer interferometry (PS InSAR) method is also explained. Current space satellite InSAR missions are also described. Finally, we describe the source of errors due to the sensing of the Earth's surface at a certain angle, and we note the advantages and disadvantages of the technique and the suitability of applying the method in various locations currently threatened by slope deformations in Slovakia, where positive results of the scientific community could be expected with the InSAR and PS InSAR methods.
