Evaluation of water use efficiency of short rotation poplar coppice at Bohemian-moravian highlandsHlaváčová, Marcela January 2014 (has links)
The diploma thesis provides basic characteristics of short rotation coppice plantations, then the most significant short rotation coppice species cultivated in the Czech Republic are described. The detailed description of particular Populus L. clone J-105 grown at the plantation of the Test Station Domanínek Ltd. follows. Afterwards, key determinants of short rotation coppice yield are presented in the text. The last theoretical part of the thesis deals with water use efficiency (WUE) with emphasis on the method used at the experimental plantation in Domanínek. The methods of sap flow measurements and biomass determinations are described for this purpose. The main aim of the practical part of the thesis is to determine WUE of 16 measured trees where sap flow measuring systems were installed. These trees are divided into 3 cohorts according to diameters at breast height (DBH) at the beginning of the growing season 2013. The additional measurements were carried out: phenological imaging, soil moisture measurements, LAI measurements and sapwood area determination. The statistical analysis of WUE did not show any statistically significant differences between values of WUE for individual cohorts. Only in May, the statistically significant difference between cohort 1 (trees with the thickest stems) and cohort 3 (trees with the lowest values of DBH) appeared.

Přispívá vodní stres a mezidruhová konkurence k funkční konvergenci nebo divergenci vlastností mokřadních rostlin? / Does water stress and interspecific competition contribute to the functional divergence or convergence of wetland plant species?Műnichová, Radka January 2017 (has links)
This diploma thesis is based on the experiment which took 5 years. In 52 plastic containers were planted four species wetland plants; two species of grasses (Calamagrostis canescens and Deschampsia cespitosa) and two species of sedges (Carex elata and Carex elongata). Three types of water regime were set up with: high, low and fluctuating water level, where the high and low level of water took turns after one year. One year before the data collection the strongest competitor Carex elata was cut out. For the evaluation of the role of water level (environmental stress) and removal of the dominant (competition) we selected two functional trait indicators: specific leaf area (SLA) and leaf dry matter content (LDMC). SLA is an indicator of resource strategies, competitiveness and efficiency of light photosynthesis. Species with high SLA are usually better competitors for light, but tolerate harder the environmental stress. LDMC reflects a plants investment in persistent leaf structures and therefore in nutrient retention. A significant effect of water regime on LDMC was observed in the species Deschampsia cespitosa that had higher average values of LDMC in dry water regime, which is indicating higher investment into persistent leaf structures. And the effect of the dominant removal on SLA, where the values of SLA in the containers without removed dominant were higher. Increased SLA implies increased intensity of competition for light. My diploma thesis supported that specific leaf area and leafdry matter content are important functional indicators different types of stress conditions in wetland communities.

Ekofyziologické a morfologické rozdíly mezi domácími a invazními populacemi \kur{Lythrum salicaria} L. / Ecophysiological and morphological differences between native and invasive populations of \kur{Lythrum salicaria} L.KAŠPAROVÁ, Františka January 2011 (has links)
Native to Europe and Asia, Lythrum salicaria is an invasive element on some other continents. Plants in the invaded areas are more robust, higher, and generally more successful compared to individuals in their original area. Based on my results these characteristics cannot be explained by neither higher photosynthesis, chlorophyll and carotenoid mass, nor specific leaf area.

Záchranné práce při požáru plavidla na vodní ploše s ohledem na vybavenost stanic JPO HZS Jihočeského kraje / The Rescue Operations at Fire of the Watercraft on Water Surface Considering the Equipment of Fire Station on the South Bohemia.BOUBAL, Vojtěch January 2013 (has links)
At the beginning of thesis I want to describe few primary characteristics of the South Bohemia Region. It is a region with unique characteristics, which is frequently visited by domestic and foreign tourists. It is popular for its clean environment, historic monuments and especially for sport and recreational activities near water areas, which South Bohemia region has plenty of. Tourists are also frequently seeking recreational boating activities as ferry services for their travel and recration. The development of this economic phenomenon means more employment opportunities for the region, but it also increases chances of accidents and emergencies due to an unforseen accidents which can threaten the lives and wellbeing of the crew and the environment. Fire protection units should be fitted for an emergencies such as: drowning, drowned person search, icy water search and rescue and rescue in stream waters. The thesis is divided into the theoretical and the practical parts. The theoretical part deals with the definition of basic terms describing the issue of fire of the vessels as well as the tasks and procedures during fire fighting operations. It also presents a possible danger to rescuers exposed during operations such as rescue from the vessel burning on the water. There is a listing of the basic terms related to the complex vessel shape and the aquatic characteristics of the vessel. The practical part deals with the study of publications and current legislation, analysis of the Fire protection Units equipment and their readines for rescue work in case of a vessel fire. The enclosed data map illustrates a water area with ferry service in the South Bohemia Region and selected boarding platforms for fire protection units. It describes the use of container technology; modern and economical way of transportation used by the Fire and Rescue Service of South Bohemia Region since 2004. The proposed fire vessel, mounted on a standardize container frame and equipped with special container with stored technical equipment will be transported to the location of event by container carrier from FRS of South Bohemia Region. My theosis also describes the fire protection, fire equipment, personal protective equipment, equipment for working with hazardous substances, rescue tools, communication and portable emergency equipment which is normally used by the fire units of FRS of South Bohemia Region. To achieve the objective of the thesis and to answer the research questions, I did rely on the reference material obtained via search of the professional literary sources relevant to the Fire Fighting equipment and carrying out rescue work. To process the diploma thesis I did use the following: controlled interview with the station sergeants of various fire stations of FRS of South Bohemia, a collection of internal acts of the Ministry of Interior - General Directorate of Fire Rescue Service of the Czech Republic, a collection of internal acts - Regional Directorate of FRS of South Bohemia, Regulations of Mechanical services of FRS of CR and the methodological aids of the Ministry of Interior of CR. In conclusion I am describing the container of fire vessel and its use for rescue and fire-fighting work on water, as well as places where the terrain does not allow the use of mobile fire fighting equipment.

Územní plánování v záplavovém území řeky Dědiny / Spatial planning in the flood area of the river DědinaPetříčková, Zuzana January 2017 (has links)
Spatial planning in the flood area of the river Dědina Abstract The delimitation of new development areas in flood area of river is one of the steps leading to the increase of flood risk. The aim of this master thesis is to find out whether and for what reasons is the delimitation of new development areas happening in territories which are at risk of flooding. At the same time, the thesis also focuses on the role of the mayor, especially his competencies related to the management of flood risks, arising from his function. Theoretical part is based on discussion about the development of cooperation between society and natural environment and also concept of Flood Risk Management, especially in relation of the flood risk with the process of urban planning and also with the organization of public administration.
