Floristic research in the basin of Pozdeňský and Bilíchovský creeks of Slánsko
BERANOVÁ, Hana
ANNOTATION Hana Beranová University of south Bohemia in České Budějovice {--} Faculty of education {--} department of biology Course: M7504 Teacher for grammar schools Fields of study: Teaching of biology, Teaching of chemistry Floristic research of catchment area of Pozdeň stream and Bílichov stream round Slaný Diploma thesis 2008 The study deals with a description of vegetation of catchment area of Bakov stream and Zlonice stream. In title of study are used the names Pozdeň stream and Bílichov stream, but it{\crq}s only local description. The search had been realised during the vegetation seasons of the years 2006 and 2007. There are characterised geological-petrographical, soil, climatic, hydrographic ratios and basic phytogeographical characteristics of this area in the form of a search. Selected genera of the observed plants are characterised and their incidence is figured in the schematic map of the area. There were found out 299 genera of plants, from which there are 48 stated in the Červený a černý seznam cévnatých rostlin České republiky (stav v roce 2000) (Procházka F. (ed.), 2001). There are described locations of important genera of plants. In discussion of the thesis are described factors, which influence the incidence of some genera of plants. In the annex there are attached schematic maps with places of occurence of the plant genera and photographic documentation. Head of the diploma thesis: Mgr. Rostislav Černý, CSc.

Comparison of precipitation and runoff in the research area Jenin in relation to nitrates.
ŠULCOVÁ, Lucie
The influence of precipitation on runoff characteristics of tile drainage systems and nitrate concentrations in drainage water were evaluated in this thesis. The Jeninsky stream catchment is located at the foothill of Sumava Mountains near the border checkpoint Dolni Dvoriste. Extensive agriculture (pasture) is practised in the catchment as well as surrounding areas. Above mentioned evaluated characteristics were measured on two closure profiles of tile drained subcatchments. Discharges were measured continously, water quality was sampled forthnigtly. Evaluated hydrologic year 2007 was rich in rainfall {--} the precipitation amounted to 892 mm, which is classified as a wet year, despite of 41 days long dry period. Runoff characteristics don{\crq}t vary much in both subcatchments, due to similar area and land use on researched catchments. Long dry period did not cause zero discharges. The progress of nitrate concentrations in subcatchments is characterized by low variations in values. Relatively low values (90-percentil of nitrate concentrations in individual catchments belong to II. and III. class of water quality limits set by Czech legislative) occured in the catchment. These values correspond or slightly exceed values monitored on surrounding simirarly used areas, but are significantly lower than values monitored in areas, where intensive agriculture is practised. This confirms positive influence of grassing on nitrate pollution of drainage and surface water.

Elaboration and interpretation of map materials in GIS for the Ostrice stream catchment.
HOUDEK, Jiří
The aim of the thesis was the creation and interpretation of thematic layers for the Ostřice stream catchment. First step was collecting all the available maps and comparing them with the actual state. The documents were digitized, and the thematic layers were created. The map outputs were created from these layers and their combinations and were analyzed. The output of this work is a set of GIS layers for the Ostřice stream catchment. This work was processed with the ArcGIS Desktop 9.1 software.

Elaboration and interpretation of map materials in GIS for the Zdikovsky stream catchment.
ADÁMEK, Petr
The aim of this thesis is to create various thematic layers for the Zdíkovský stream catchment. The first step was to collect maps and compare them with the actual state, followed by the digitizing of these documents and the creation of thematic layers. Map outputs were created from the individual layers and their combinations and were analyzed. The result is a set of GIS layers for the catchment. ArcGIS Desktop 9.1 program developed by ESRI was used in this work. Elaborated set of layers will be further used for research and educational purposes by the Department of Land Adjustment.

Solution of soil protection from erosion in model catchment - Zvíkovský stream
ŘEHOUT, Jan
The theme of my graduation theses is a solution of the soil protection from erosion on the model catchment of the Zvíkovský stream. The aim of this work is canvass of the catchment Zvíkovský stream in the view of the pedology, hydrogeology, climatology and calculate the soil loss from the areas in consequence of the water erosion. I used the equation losses of the soils from the area according Wischmeier and Smith and the assesment of the transporting the sediment runoff according Williams and Berndt which was calculated with the help of the programme ERCN {--} the enumerations required for the suggestion of the precautions from erosion. The map basis of this work is the basic map of the Czech republic 1: 10 000 and the water utilization map of the Czech republic 1:50 000.

Cration of digital terrain model for the Jeninsky stream catchment and analysis of valley lines.
JURÁNEK, Stanislav
The aim of the thesis is localization and interpretation of paths of concentration runoff in digital terrain model. Digital terrain model(DTM) is processed for the catchment of the Jenín stream, where The Faculty of Agriculture has held the research since the year 2004. For creation of DTM following software programs were used for comparison: Erdas and ArcGIS. Digitalized maps of contour lines for this catchment were the backgrounds for creation of the DTM. Localization of paths of concentration runoff and natural thalwegs was made on created DTM. Then was the comparison of models and the real topography of the catchment realized. Possible reasons of differences were discussed in discussion. Different (in colours and resolution) variations of DTM with localized paths of concentration runoff are the result, with the view of better legibility and more truly representation of real topography of the landscape.

The evaluation of land use changes in last 50 years in the catchment of Jeninsky stream.
CEPÁK, Martin
It is in human nature to adapt the environment for his needs and wishes. Politics, technology and society as a whole went trough dramatic changes in Czech Republic in last 50 years. These changes approved naturally on land utilization too. This research is focused on the evalution of land use changes in last 50 years in the catchment of Jenínský stream. The research is based on photogrammetric scans from years 1952, 1974 and 2005. Polygon maps of land use in GIS were elaborated from these scans. Outputs of these maps were subsequently analysed and mutually compared.

The occurrence of brook lamprey [Lampetra planeri (BLOCH, 1784)] in Novohradské Mountains (South Bohemia, Czech Republic)
Matěnová, V. ; Matěna, Josef
The occurrence of brook lamprey was studied in Novohradské Mountains during 1999-2003. Altogether 83 profiles on 22 second to fourth order brooks and streams were fished by means of electroshockers. The area investigated can be divided into three basins. Significant differences were found between basins with respect to frequency of occurrence and density of lamprey populations. The highest frequency of occurrence was in the Stropnice River basin (6 streams of 8 investigated, average abundance 2598 inds ha-1), followed by the Malše River (4 streams of 8 investigated, average abundance 844 inds ha-1). In the Černá Rivulet basin only in 1 of 6 streams investigated the brook lamprey was found at very low densities - 28 inds ha-1 on average. The lamprey contributed substantially to the whole forming more than 50
