The introduced graduation theses deals with the issue of legal regime of land associated with water. In the four major fields, which are water courses, land relations in area protection of water, land relations in areas endangered with high flood and land relations connected to waterworks, the theses analyses legal regulations of land relations with the emphasis on limitations of ownership, which conclude from these relations. In the center of attention of the theses are the laws in the water act, laws which are inferior to the legal force of the water act and laws in the new civil code.

O fósforo é um elemento essencial para todas as formas de vida na Terra, podendo ser introduzido no ambiente aquático através de fontes naturais ou antropogênicas. A avaliação deste elemento em ecossistemas aquáticos é de suma importância, uma vez que ele atua na regulação da produtividade primária. Logo, este trabalho teve por objetivo avaliar a distribuição das diferentes frações do fósforo no sedimento superficial dos rios Aracaí, Carambeí e Guaçu na cidade de São Roque- SP, a fim de avaliar possíveis impactos antrópicos na qualidade das águas. Para tanto, foram realizadas quatro coletas de amostras de sedimentos nos meses de março, maio, julho e setembro de 2017 e avaliaram-se cinco pontos amostrais (A1, C1, G1, G3 e G4) sendo, dois a montante das cabeçeiras dos rios Aracaí e Carambeí e três ao longo do rio Guaçu, onde determinaram-se as concentrações de fósforo, juntamente com os parâmetros físico-químicos (umidade, granulometria, pH, e matéria orgânica). Os teores de sedimentos finos e de matéria orgânica foram os principais parâmetros ambientais correlacionados com as frações de fósforo. O método analítico utilizado foi o Protocolo desenvolvido pelo Standards, Measurements and Testing (SMT), que fracionou o fósforo dos sedimentos em: total (PT), inorgânico (PI), orgânico (PO), não apatítico (PINA) e apatítico (PIA). Observou-se que as maiores concentrações ocorreram nos sedimentos do ponto G1 da segunda coleta com 1839,6 mg kg-1 para PT e que os teores de PI foram maiores que os de PO em todas as coletas realizadas. / Phosphorus is an essential element for all forms of life on Earth and can be introduced into the aquatic environment through natural or anthropogenic sources. The evaluation of this element in aquatic ecosystems is of paramount importance, since it acts on the regulation of primary productivity. The objective of this work was to evaluate the distribution of the different phosphorus fractions in the surface sediments of the Aracaí, Carambeí and Guaçu rivers in the city of São Roque, SP, in order to evaluate possible anthropogenic impacts on water quality. Four samples of sediments were collected in March, May, July and September of 2017, and five sample points (A1, C1, G1, G3 and G4) were evaluated, two upstream of the river headwaters Aracaí and Carambeí and three along the Guaçu River, where the phosphorus concentration was determined, together with the physical-chemical parameters (humidity, grain size, pH, and organic matter). The levels of fine sediments and organic matter were the main environmental parameters correlated with the phosphorus fractions. The analytical method used was the protocol developed by Standards, Measurements and Testing (SMT), which fractionated phosphorus in: total (PT), inorganic (PI), organic (PO), non-apatite (PINA) and apatite (PIA). It was observed that the highest concentrations occurred in the sediments of the G1 point of the second collection with 1839.6 mg kg-1 for PT and that the contents of PI were higher than those of PO in all collections.

The thesis describes a period of the government of Leopold II Grand Duke of Tuscany and his affiliation to the swampy territory along the Tuscany coastline called Maremma and its bonification. He was able to change fundamentally the most underdeveloped areas of his country during thirty years of his government. He succeeded even though political changes during the revolutionary years of 1847-1849, and though his government was finished by the unification of Italy and the incorporation of Tuscany into the newly established Kingdom of Italy, which was the goal of Italian risorgimento. This work further describes biography of Leopold II in short, his policy focused on overall development of Tuscany, and last but not least life fates and the principal works of his three closest collaborators - personalities with major influence at the realisation of the bonification works - Vittorio Fossombroni, Gaetano Giorgini and Alessandro Manetti. The thesis describes the bonification works in Maremma themselves, their organisation and results achieved. Part of the bonification overall plans of Leopold II was construction of the road network as well, with necessity of numerous bridges over canals and regulated watercourses. It was also necessary to solve the health problems in the region, especially malaria, where...

The objective of this dissertation is resolving the issues of both form and function of water courses in a present-day city. The dissertation focuses primarily on water courses which may be described as man-made, i.e. those resembling a canal, and addresses their prospective revitalization within the context of urban renewal and development in the present-day post-industrial era. The introduction includes a comprehensive analysis of the historical and typological development of artificial water courses, essential for grasping the connections as well as the current overall state of water courses in an urbanized setting. Detailed attention is devoted in particular to the most frequently occurring artificial water course - i.e. the race. The dissertation strives to defend the irreplaceable role of the water course as a public space in the urban landscape and - consequently - also its prospective essential revitalization. Examples, especially from throughout Western Europe, are used to demonstrate particular solutions, approaches and strategies to predominantly artificial water course renewal within the urban environment. The dissertation also devotes attention to the tools used in reaching relevant solutions.
