Abstract

Water quality is a term used to describe the physical, chemical and biological characteristic of water, generally in terms of suitability for a particular or designated use. The quality of water in river streams is influenced on the one hand by natural factors (climatic, geomorphologic...) and on the other hand by anthropogenic ones. However the most frequent is considering the water quality by the combination of both factors.

The paper is aimed on the evaluation of concentrations changes of selected indicators (arsenic and antimony) in the monitored locations as well as the assessment of the relation between arsenic and antimony mutually. The course of pollutants concentrations measured in 5 different river stations considering the place with the higher concentrations appraisal of inorganic pollutants (antimony, arsenic) is presented in this paper.

Key words: statistical methods, water quality, pollutants

Abstract

A comprehensive visitor management is one of key prerequisites for successful and sustainable management of natural environment and regional development. On the one hand visitor management is necessary because of the environmental protection. Appropriate visitor management can also maintain or encourage visitors` experience. Tourism is also a very important factor for social and economic development of regions. Proper visitor management should be based on the results of quality visitor monitoring. Unfortunately, the issue of monitoring and communication with public is underestimated for a long time in the Czech protected areas.

This paper deals with the performance of different methods of visitor monitoring, their strengths and weaknesses, suitability for specific purposes. Interesting and often unexpected results of visitor monitoring are presented using examples from the Czech protected areas. Paper also presents mistakes and possible problems during visitor monitoring.

Key words: Counting, management, protected areas, tourists, visitor monitoring.

Abstract

The contribution is dealing with a relationship between new recreational activities and the environment with an emphasis on nature protected areas. Expected negative impacts have three dimensions in terms of sustainable development: environmental, social and economic. Those dimensions should be described in a summary of experience of dozens assessed activities - proposed recreational facilities. Strategic Impact Assessment (SEA) and Environmental Impact Assessment (EIA) are fully compatible with the concept of sustainability, which is the basis of impact assessment. These preventive tools – as EIA for 525 activities, so SEA for the national plan - are used in Slovakia. The summary of predicted impacts and a new dimension in the assessment - Integrated Biodiversity Impact Assessment (IBIA) are described in the contribution.

Abstract

The development of medieval society was bound to countryside row material potential. Important factors in this respect were the natural resources and their utilization. Slovakia's mountain character was well known since ancient times as a source of raw materials across the mountains. There are known deposits of metals and traces of mining under Krivan, even traces of metals in the primordial seekers in Spania Dolina, Kremnica, Banska Stiavnica, and a variety of foundries and mills for processing metal in other locations of Slovakia. In today's era have been preserved many technical devices which aim is to use natural resources in Slovakia. Articles assess the dynamics of development of activities in the Stiavnica Hills and evaluate potential areas in terms of tourism at the evaluation of landscape closed to reservoir Velky kolpassky tajch.

Abstract

Slovak Republic has lot of rural settlements with hidden, still undetected and idle potential. Osadné village, that is placed on North-East of Slovakia, has special conditions to attract many tourists, however this conditions are not used yet and also the basic service and proposal are missing.

This script presents a complex approach to a solution of situation in the village and presents also an ambition to create some attractive a multifunctional environment for its inhabitants and perspective tourists in this beautiful ambient of National Park Poloniny. The proposal includes the whole village, its centre, also ambient of the village and connection to the existing tourist paths, enriching them with new attractive elements for tourists. Presuming to a successful solution and presentation of the concept is to activate inhabitants of the village and co-work with them: support the participation, accept their needs, ideas and schemes, and join them to the realisation and maintenance of designed, sustainable proposal.

Abstract

Monitoring of microclimate regime and evaluation of visitors influence to air temperature changes in Kateřinská Cave were evaluated based on the average fifteen-minute data from March to August 2010 and 2011. Selected episodes were evaluated in detail by minute records. Daily amplitudes of air temperature (quantified as the difference between daily maximum air temperature and air temperature at 7 am) were correlated with the daily number of visitors. Maximum daily amplitude of air temperature (1.99°C) was recorded in the most dynamic part of the cave - the entrance corridor in March. The maximum amplitude (0.50 and 0.68°C) in remote end parts of the cave was recorded in summer when tourist season culminate (5^th July 2010, 790 visitors). The closest correlation between daily amplitude of air temperature and number of visitors was observed during summer in “Hlavní dóm” hall (July 0.803; August 0.849) and near "Bambusový lesík" locality (June 0.896; July 0.875; August 0.885) where a few minute stops are carried out in frame of tourist route. Daily air temperature fluctuations of cave temperature include changes caused by visitors as well as natural daily fluctuations. Daily air temperature changes inside the cave can be explained from about 60% by visitors influence and about 15% by interaction with external environment.

Abstract

Nowadays is essential a appropriate pavement design and one of the most used are flexible pavements. These kind of road have different layers, where deformation are formed due to the load that have to withstand. These deformation can be recover or permanent. And here is when the concept of resilience module appears. This module is related to the process of repeated load. Under the moving load the permanent deformation is accumulated and in the intermediate cycles, the permanent deformation for each cycle is decreased until it almost disappear in the final cycles. In this moment the sample arrive thus a state which all deformation is recoverable and this is the moment where it have a resilience performance.

The module can be measured with different tests. One of the most frequently test is the CBR, but is not exact, so one of the best method is a cyclic triaxial test. It is a complicated and expensive method, so that why nowadays are investigating other methods such as finite element.

Abstract

In Senianska wetland area as a part of East Slovak Lowlands situated on the left bank side of the Čierna voda River above its junction with the Laborec River, periodic floods were stopped because of agricultural requirements after the year 1970. Such measure led to the total disposal of wetlands in this region. Few years ago several researches were authorized to design and provide in this locality (Senianska depression) such measures, which could help to retain ecological demands and bird reserve. Nowadays flooding of this area is planed, which can provide the restoration of local wetlands and soil water regime improvement, as well.
