Extreme hydrological phenomenons in landscape
Kallabová, Eva ; Munzar, Jan
Extrémní hydrologické jevy (povodně) jsou nejobvyklejší přírodní katastrofy; přesto i v souvislosti s nimi dochází k rychlé ztrátě historické paměti. Dochovanými připomínkami starých extrémních povodní v krajině jsou mj. různé formy hmotných památek, zejména povodňové značky či památníky obětem povodní. Jejich dokumentace, klasifikace a popularizace je jedním z pokusů obnovy historické paměti ve smyslu nutného neustálého připomínání existujících rizik současné (a budoucí) populaci.

Finanční ohodnocení krásy krajiny - metoda CVM
Cudlínová, Eva ; Lapka, Miloslav
Evaluation of landscape amenity is not very common and relatively difficult from the economic point of view. In our case study focused on comparing aesthetic preferences of Czech and Japan respondents regarding rural landscape. We used the contingent valuation method. We also wanted to reveal the respondent’s preferences in a financial form. These preferences served us as quantitative indicator for an attestation of the respondent’s qualitative preferences. It seemed that a strong correlation between the aesthetical and financial evaluation exist in two extreme cases – respondents were not interested, or they were strongly involved in landscape amenity. A substantial difference occured between the Czech and Japanese respondents in the case of case of open or closed access to the landscape.

Short rotation coppices and water management of landscape
Weger, J. ; Šír, Miloslav ; Syrovátka, O.
Short rotation coppices (SRCs, energy forest) became an accepted method to produce biomass for energy. The positive environmental effects of using biomass as a bio-fuel (e.g. reducing GHG, air pollution) were scientifically proved and these effects are now being used as the main argument in the discussion on whether the establishment of large plantations of SRC should be supported and subsidised. Much less is known about the other non-productive effects (functions) of an SRC on the cultural landscape and agro-ecosystems, which may have also positive effect on quality of the environment.

The evolution of Bečva river stream channel after the flood of 1997 ů the significance for research and protection
Kirchner, Karel ; Lacina, Jan ; Krejčí, O.
The flood of July 1997 altered the stream channel of middle and downstream reach of Bečva river in a significant way. Lateral as well as depth erosion removed upper layers of floodplain sediments and created new well pronounced two-level channel with variety of other fluvial forms, which have profoundly increased the biodiversity of the floodplain landscape. We focused our attention on apprehension of selected long persisting effects of flood on relief, rock environment and floodplain ecosystems as well as the possibilities of their conservation within the selected areas in the vicinity of Choryně (Vsetín District)
