METODA IDENTIFIKACE TEKTONIKY NA ZÁKLADĚ ZMĚNY ŠÍŘKY ÚDOLNÍHO DNA (NA PŘÍKLADU VSETÍNSKÉ BEČVY)

The paper deals with the identification of fault tectonics on the basis of topographic maps analysis. The investigated parameter is the valley floor width in the drainage basin of the Vsetinská Bečva River. In the first stage it is necessary to determine theoretic profile of the valley floor width downstream increment. For its construction has been used the magnitudo (Shreve 1966). In the next stage the deviations were calculated between theoretic and real profile of the valley floor width. These deviations were divided into groups according to their lithology and their orientation to prevailing direction of strata. The sections whose deviations were anomalous to average of groups are presumed to be affected by tectonics. This method is suitable as preliminary step for the following field investigation

Benefits and challenges of collaborating with volunteers: examples from national wildlife roadkill reporting systems in Europe

Daily, a large number of animals are killed on European roads due to collisions with vehicles. A high proportion of these events, however, are not documented, as those obliged to collect such data, only record a small proportion; the police only register collisions that lead to traffic accidents, and hunters only collect data on game wildlife. Such reports disproportionately under-records small vertebrates such as birds, small mammals, amphibians and reptiles. In the last decade, however, national wildlife roadkill reporting systems have been launched, largely working with citizen scientists to collect roadkill data on a national basis that could fill this data gap. The aim of this study is, therefore, to describe for the first time, existing projects in Europe, and the user groups that submit data to them. To give a deeper understanding of such projects, we describe exemplar scientific roadkill reporting systems that currently exist in Austria, Belgium, Czechia and the United Kingdom. We define groups of people who contribute to such citizen science activities, and report our experience and best practice with these volunteers. We conclude that volunteers contribute significantly to collecting data on species that are not typically recorded in official databases. To ensure citizen-science projects perpetuate, (I) volunteers need to be motivated by the organisers to participate on a long-term basis, (II) volunteers need support in identifying roadkill species where required, and (III) regular feedback is required on how their contribution is used to produce new scientific knowledge

DETERMINING ROAD NETWORK ROBUSTNESS AND PROPOSALS FOR ITS IMPROVEMENT

V příspěvku je aplikována metoda pro stanovení robustnosti sítě na dvě části silniční sítě Zlínského kraje. Dále je ukázáno, jak lze tuto metodu použít při návrhu nových spojení, které mají za cíl maximálně zvýšit jejich robustnost. Výsledkem výpočtů je návrh několika alternativ, jež mohou být k dispozici expertovi pro konečný výběr vhodného spojení.A method for measuring network robustness is applied to two parts of the Zlín region road network. We demonstrate how this method can be used to design new road links whose objective is a maximum increase in the entire network robustness. The computation results are several alternatives which should help experts make a final decision when choosing the most suitable link

PŘEDBĚŽNÉ VÝSLEDKY SEDIMENTOLOGICKÉHO STUDIA PŘEHRADNÍCH SEDIMENTŮ NÁDRŽÍ HORNÍ BEČVA (BESKYDY) A PASTVINY (ORLICKÉ HORY)

Bottom sediments of Horní Bečva and Pastviny reservoirs were studied during reservoir draining in year 2000. Three sedimentary facies were defined: 1. delta (mostly sand with intercalation of gravel and phytodetritus), 2. streamline affected sediments (alternation of silty muds, sands, silts and phytodetritus intercalations), 3. calm sediments (muds deposited from suspension). Special features of sedimentation in dam basins are discussed. As a useful stratigraphical tool the finds of artefacts were used for dating some sequences. The sedimentation rates for the muds deposited from suspension are estimated 13,9 to 14,4 mm/y for Horní Bečva and 8 to 9 mm/y for Pastviny reservoir. The sedimentation rates in other facies are difficult to estimate. The total sediment accumulation of flooding in 1997 and subsequent two years recognised in Horní Bečva reservoir through different facies can serve as sure approximation: 3 to 7 cm in the calm areas, 40 cm in the streamline and 90 cm in the delta. 25 to 81 cm of streamline sediments represent the same time interval in the Pastviny reservoir
