Σκοπός αυτής της Διπλωματικής εργασίας είναι η αποτύπωση της κατάστασης των πρανών κατά μήκος του επαρχιακού οδικού δικτύου Τσουκαλάδων-Αγίου Νικήτα, όπου ενεργοποιήθηκαν οι καταπτώσεις βραχοτεμαχών μετά το σεισμό της 14ης Αυγούστου του 2003 που έπληξε το νησί της Λευκάδας. Στο πλαίσιο της προκείμενης εργασίας γίνεται προσπάθεια εφαρμογής υπολογιστικών μεθόδων στην κατάπτωση βράχων σε συνθήκες στατικής και δυναμικής φόρτισης με σκοπό τον προσδιορισμό και σχεδιασμό μέτρων πρόληψης και προστασίας στο πεδίο. Η εργασία περιλαμβάνει αποτύπωση και χαρτογράφηση της ζώνης καταπτώσεων, και τα αποτελέσματα από την παρατήρηση στην ύπαιθρο. Η σπουδαιότητα των στοιχείων αυτών έγκειται στην κατανόηση του ευρύτερου γεωλογικού περιβάλλοντος που ανήκουν οι βραχώδεις σχηματισμοί, των οποίων ο τύπος καταπτώσεων διερευνήθηκε.

Ports are the foreign gateway for countries and regions, and it is playing an increasingly important role in the world economy. While embracing the economic benefits brought by port development, Chinese ports are also faced with an unprecedented number of environmental problems. The overall goal of this thesis is to explore the similarities and differences between Canadian and Chinese ports in terms of their environmental protection policies, environmental management, and environmental protection measures. The thesis also aims to sum up valuable environmental protection experiences from both countries, in an effort to provide a reference guide for environmental protection activities in China. In this paper, many research methods have been used, including a review of the literature, site inspection, expert advice and case analysis in order to explore the similarities and differences in policies, concepts and measurements of port environmental protection in Canada and China. This information will be used to define the advanced concepts, managerial methods and measurements of environmental protection in Canada that Chinese government departments and port authorities could learn from. Through this study, suggestions will be made regarding what China's port sectors can learn from Canada in the following areas: (1) connecting port authorities with relevant environmental protection experts to carry out environmental protection research; (2) expanding the scope of port environmental protection, paying attention to co-operation with other agencies to protect the environment; (3) enhancing the protection of the ecological environment of the port， (4) paying attention to public participation in the process of port environmental protection; and (5) upgrading the environmental protection management concept on the part of port managers. It will be suggested that from Canada, relevant Chinese government departments should learn to (1) promulgate operational laws and regulations related to port environmental protection; (2) set up port management institutions to improve the port environmental management; (3) clarify the role of government departments, ports and environmental regulatory authorities in the course of the environmental protection; and (4) strengthen enforcement and regulations. In addition, it will be suggested that the enhancement of public awareness regarding environmental protection be continued and that relevant laws be passed to expand the scope of public participation.

The practices of solid waste management (SWM) and solid waste disposal (SWD) in Kano metropolis, Nigeria, were examined. The water quality of groundwater sources in the areas adjacent to the SWD sites was monitored in order to evaluate interactions and assess the possibility of groundwater contamination as a result of percolation of the leachates generated in the SWD sites. An integrated approach to the field investigation was employed in the study. This included an extensive desk study; a field survey of all existing SWD sites in the area; leachate and groundwater sampling; and laboratory-based experimental and instrumental analyses. The locations of the SWD sites relative to inhabited areas were examined, and eight sites and their environs were selected for leachate and groundwater sampling and quality assessments in May 2009 and May 2010. It was observed that SWM activities in Kano metropolis are unsystematic and pose a significant risk to both public health and environmental quality, especially in relation to local groundwater sources. It was also found that the leachates produced in the sampled sites contained significant concentrations of a wide range of contaminants; including nitrates, total alkalinity, total dissolved solids, chlorides and sulphates. The leachates were also observed to be in the methanogenic phase of biochemical degradation and were shown to have similar characteristics to other leachates from mature SWD sites in different parts of the world. Similarly, the physico-chemical characteristics of the groundwater samples around the selected SWD sites indicated high concentrations of nitrates, chlorides, total dissolved solids, total alkalinity, turbidity, iron and manganese, often above the WHO thresholds for acceptable drinking water quality. It is, therefore, concluded that the shallow groundwater sources analysed have been contaminated, due largely to improper SWM practice. This, in turn, affects not only the health and well-being of the local population, but also impedes developmental efforts and obstructs prosperity. Accordingly, some strategies for pollution prevention and control were developed for Kano metropolis, although they are also applicable to other urban areas with similar characteristics. These strategies, which are largely categorised as resource-focused, source-focused or remedial measures, can be achieved through: (1) identification and mapping of pollution sources; (2) establishment of databases and information management system; (3) vulnerability mapping; (4) establishment of functional monitoring and evaluation system; (5) promotion of public awareness and participation; (6) establishment of protection zones; and (7) the integration of pollution prevention and control strategy into urban planning, development and management of municipal services.

Master´s thesis deals with the evaluation of the effectiveness and efficiency of the proposed flood protection measures in the affected area between the low Nové Mlýny reservoir and Pohansko weir at the Dyje river. The evaluation was done using the multicriteria decision analysis. The analysis was based on hydraulic calculations using 2D hydrodynamic model.

This diploma thesis deals with assessment of flood protection measures in Břeclav. Hydraulic calculations of proposal flood events were carried out using 2D numerical model of water flow. Several simulations took account of construction phases and different values of proposal discharge. The hydraulic calculations were computed for river Thaya including its relief branch. The results were processed in the form of inundation maps, depth maps and they were recorded in longitudinal profiles of rivers.

Diploma thesis deals with design of a flood protection a controlling structures with respect to problém of inner waters in the area of interest. The river reaches assessed are located mostly in the urban area of the city Letovice, more precisely from the junction of the Svitava and Křetínka river. The reaches are at kilometer 59,608 – 61,520 of the Svitava and kilometer 0-1,752 of the Křetínka river including the race between them. Program MIKE 11 (developed by Danish hydraulic institut) was used to calculate the water levels as nonuniform flow.

The Diploma Thesis consists of research and design part. The content of research part is description of dry reservoirs and theory of 2D modelling. The design part of the work deals with the hydrotechnical study of possibility of building a dry reservoir Blučina in two variants of designs of reservoir with objects. The design contains simulations of 2D numerical model of reservoir made in program SMS-SRH of both designed variants. The result is evaluation of both designed variants and recommendation of better option for a possibility of construction in the future in terms of the transformation of the century-flood wave.

Für einen sicheren Herdenschutz in Gebieten mit frei lebenden Wölfen ist der Einsatz von Herdenschutzhunden in Kombination mit Elektrozäunen zu empfehlen. Der Umgang mit Herdenschutzhunden erfordert Sachkenntnis und Verantwortungsbewusstsein. Die Broschüre erläutert Unterschiede zum Hütehund, beschreibt Grundlagen der Sozialisierung und die wichtigsten Rassen. Im zweiten Teil werden Untersuchungsergebnisse zu verschiedenen Varianten der Elektro-Umzäunung dargestellt, insbesondere zur benötigten Arbeitszeit beim Aufbau der Netze. Im Ergebnis der Analyse wird eine übersprungsichere Variante empfohlen, die mit vertretbarem Zeitaufwand aufgebaut werden kann und den Herdenschutz gewährleistet.
