A little overview of drought history of the Punkva River, focusing on the year 2018
Lejska, S. ; Kuda, František ; Kněžínek, K.
Since 2012, one can observe a decreasing trend in the water level of underground karst water in the Punkva River basin. In 2018, the discharge at LG Skalní Mlýn dropped to the lowest value in the last 60 years (75 l.s-1). This permitted a dry entry to the Lake Dome forming the inflow sump of the Punkva River to Bludiště Milana Šlechty (Milan Šlechta Labyrinth) in the confluence area of the Sloup Creek and the Bílá voda Creek, in the central part of the Amatérská Cave. The sump is adjacent to the Jezerní propast (LAke Abyss) The connection between these two locations had not been surveyed at that time, so our work group „Lake Abyss – inflow sump of the Punkva River“ scanned this section using a 3D scanner in August 2018.

Searching for springs of the river Punkva
Kněžínek, K. ; Kuda, František ; Lejska, S.
The paper is devoted to exploration of hydrological conditions in the confluence area of streams Sloupský creek and Bílá voda creek, which is located in the Amateur Cave in the Moravian Karst. Somewhere in this complex part of the Amateur Cave arises river Punkva. The research attempting to connect hydrological data from water level gauges placed at selected locations and 3D model of the cave created by using laser scanning. The result should be hydrological model of studied part of the cave, but acquired data have potential for further research.
