To distribution of Quaternary sediments on the Červený kopec (Red Hill) in Brno.
Demek, J. ; Havlíček, M. ; Kirchner, Karel ; Nehyba, S. ; Lisá, L.
Complex of Quaternary sediments was exposed on the SE slope of the Červený kopec (Red Hill) in the southern part of the Brno city. The Hill bedrock is composed of red quartzose conglomerates and arkoses of Lower Devonian age (“Old Red”). The authors found several bodies of fluvial gravels and sands in the exposure deposited as river terraces by the Svratka river. The highest gravel body (surface cca 241 m, base cca 235 m a.s.l.) can be compared with Tuřany terrace of the Svitava R. dated paleontologically into Danubian Period.

Influence of land-sliding on the relief of the NE part of the Vizovická vrchovina Highland
Kirchner, Karel ; Roštínský, Pavel
Altogether, 10 maps in a scale of 1:10.000 documenting slope deformations in the NE part of the Vizovická vrchovina Highland were made in the course of years 2000-2004 during engineering-geological survey (cca 450 localities). 3 main types of land-slides were distinguished, majority of them developed in a deluvial material: 1) land-slides generated in thick coluvial deposits on the slopes of structurally-controled ridges, 2) land-slides in central parts of slopes, being without direct connection to the drainage-network and 3) the most wide-spead land-slides being related to the present fluvial system. The great number (19%) of land-slides is situated in dry slope dells and amphitheatrical valley-heads. These types of depressions represent transitional forms between land-slides and valleys and seem to be evolving through alternating phases of sliding and fluvial depth erosion.

Current state of physico-geographical investigations in the Institute of Geonics, Academy of Sciences of the Czech Republic
Kirchner, Karel
Physico-geographical investigations in the framework of the Institute of Geonics, Academy of Sciences of the Czech Republic are carried out in the Department of Environmental Geography in the Brno Branch. Geonics was defined as a science which studies the substance of processes occurring in the Earth crust due to anthropogenic activities including environmental impacts. Activities of the Brno Branch are concentrated on an evaluation of human impact on landscape and a study of the interactions between nature and society. The investigation in the Brno Branch has the direct link to the regional geography, that frequent trend of the Czech regional geographical research is solution of environmental problems in regions. Physical geographers solve research tasks in the framework of environmental geography. Collaboration between physical and human geographers is a basic concept for research projects in the Brno Branch. In the last 10 years, physico-geographical investigation has concentrated to the partial research directions: - geomorphological investigations, - climatic hydrological investigations, - biogeographical and geoecological investigations.
