Resumo: A expansão das áreas urbanas promove consideráveis alterações no uso e ocupação da terra de uma bacia hidrográfica. Estas novas características condicionam a bacia hidrográfica a um novo regime das variáveis hidrológicas. Desse modo, antecipar o comportamento das variáveis hidrológicas passou a ser o desafio dos planejadores urbanos, pois com a redução de áreas permeáveis o volume que antes infiltrava passa a escoar superficialmente requerendo espaços para ser locado. Com o intuito de locar este acréscimo problemático da vazão as pesquisas em hidráulica e hidrologia passaram a recorrer aos modelos de previsão de vazão. Aos modelos de previsão de vazões somou-se o advento dos programas de geoprocessamento, possibilitando a estruturação de bancos de dados mais detalhados. Assim, este trabalho configurou um banco de dados no ArcMap 9.2 utilizando cartas temáticas confeccionadas no AutoCAD 2000 e planilhas cadastrais sobre o uso e ocupação da terra no Excel 2003 para a sub-bacia hidrográfica do Córrego Sem Nome, localizada no município de Ilha Solteira - SP. Esta bacia hidrográfica tornou-se um caso interessante para estudo, pois além de ser de pequeno porte, área de 3,47 km², em 45 anos deixou de ser rural e passou a ser 100% urbana, sofrendo com intensos processos erosivos. A aplicação do ArcMap 9.2 na determinação dos parâmetros da bacia de drenagem forneceu uma estimativa mais acurada dos coeficiente de runoff, parâmetros da fórmula de Horton e coeficientes de Manning. O Método do Balanço de Massas foi empregado para o cálculo das vazões, a fórmula de Horton para a determinação da infiltração e o método da onda cinética para o cálculo dos tempos de concentração dos trechos a serem analisados. Dessa forma, confeccionou-se um ferramental computacional que possibilitou simulações dos efeitos da urbanização ao longo dos anos...

These new features make the basin to a new system of hydrological variables. Thus, the challenge for urban planners was anticipate the behavior of hydrologic variables because the decrease of permeable areas decreased the volume that infiltrate, increasing runoff, requiring space to be leased. In order to resolve this flood's increase problem researches in hydraulics and hydrology are turning to predictive modeling of flow. Models for forecasting stream flow added to the advent of GIS programs, enabling the structuring more detailed databases. This paper set up a database in ArcMap 9.2 using thematic maps prepared in AutoCAD 2000 and cadastral spreadsheets about the use and land cover in Excel 2003 for the catchment area of the Sem Nome Stream, located in Ilha Solteira- SP, Brazil. This basin has become an interesting case to study, as well as being small, area of 3.47 square kilometers, in 45 years no longer rural and has become 100% urban, suffering from severe erosion. The application of ArcMap 9.2 on watershed parameters determination provides a more accurate estimate of runoff coefficient, of the parameters of the Horton's formula and of the Manning coefficients. The method of mass balance was used to calculate the flow, the Horton's formula for determining the infiltration and wave kinetic method for calculating time of concentration of watercourses to be analyzed. Thus, a simulations tool has been concocted turning possible to know the effects of urbanization all over the years, providing the peak flow for each stage of the occupation in the runoff launch. Finally, with the peak flows determined, we evaluated the efficiency of the existing drainage system in the watershed, since it was built along with the city's projected deployment Ilha Solteira - SP, Brazil / Orientador: José Augusto de Lollo / Coorientador: Jefferson Nascimento de Oliveira / Banca: Paulo Augusto Romera e Silva / Banca: Sergio dos Anjos Ferreira Pinto / Mestre

The doctoral thesis deals with the evaluation of influences of causal factors that significantly affect runoff processes in landscape. The research is mainly focused on the examination of land and soil cover impacts and partially pays attention to the effects of surface drainage and snow cover. The main effort was to find out the extent of influences of each individual factor on runoff from a different type of landscape. In order to find the correct answer, a methodical approach was applied to small experimental paired catchments where the research has been continuously undergoing since the year of 2006 (the presented results have been collected for 11 years of observations). The small experimental paired catchments are located at the foothills of the Šumava Mountains and they represent small area neighbouring catchments of similar physical-geographic and hydrographic conditions. The catchments were selected as the comparative ones where the main differences are the landscape and soil cover. Moreover, the character of surface drainage is regarded to be an important variable. In the catchment area of the Zbytinský Brook, there predominates the grassland which is largely drained by the subsurface drainage system. In the catchment area of the Tetřívčí Brook the dominant cover is formed by the forest...

It is important for practical and legal reasons that water and sediments in disturbed areas around the mining operation should be controlled. The construction of a well-designed drainage system that controls erosion and thus restores the proper hydraulic function of the surface is one of the most important post-disturbance features which should be done as part of the mining activities. However, even with the best planning and design, unless proper construction practices are adapted; both the disturbed and reclaimed areas are very much likely to be susceptible to erosion, sedimentation and stability problems. In order to tackle the problem, guidelines on how to design and construct the drainage system should be well prepared. The main objective of this study was to prepare guidelines for the proper design, construction and monitoring of the water drainage management system in the study areas (Kankberg, Maurliden and Renström-Petiknäs). This report has analysed the results from the outcome of HEC-RAS software for the case study of the new ditch around the Maurliden mine site and integrated with different guidelines. Based on the results of the HEC-RAS, the most common problems in the drainage system have been identified. Moreover the thesis project identified important physical parameters such as cross-sections and slopes of the representative ditch which affect the function of the ditch in the study areas. Hydraulic parameters such as velocity which is very important for designing the type of lining and also Froude number which is very important in identifying the type of flow whether it is super-critical, critical or sub-critical were identified. The latter helps to select the type of guideline to be used between steep slope and mild slope.

El objetivo de la presente investigación consiste en proponer el uso de un muro de defensa ribereña con sistema de drenaje LGD para cumplir con las consideraciones técnicas del terreno y mitigar el impacto económico – social causado por el desborde del río Rímac, en el tramo de estudio desde el Puente Colgante ubicado en la Av. Arequipa hasta el Puente Estela Montti, en la ciudad de Chosica. A lo largo de los años, el asentamiento humano, Clorinda Málaga, que reside próximo al margen del río Rímac ha sido afectada constantemente por el desbordamiento del Río Rímac generando grandes pérdidas humanas y materiales. En la actualidad, la Municipalidad Distrital de Chosica tiene medidas de prevención contra estos fenómenos de inundación, pero son poco eficientes y no generan seguridad, puesto que son soluciones temporales. Para lograr el objetivo planteado, se realizaron los siguientes estudios previos: Evaluación de vulnerabilidad y riesgo; Análisis de riesgos de inundación; Estudio Hidrológico e Hidráulico y Modelación en Software. Luego, se procedió a diseñar y presupuestar muros de defensa ribereña convencionales y no convencional, con la finalidad de evaluarlos en base a su eficiencia, factores técnicos y costo/beneficio. Como resultado, el diseño del muro planteado no es posible de seleccionar para su ejecución, ya que el ancho de su cimentación supera lo permitido por las consideraciones técnicas del terreno. Por ello, se recomienda ejecutar para las zonas críticas del tramo en estudio, un muro de concreto armado (aguas arriba) y muro de concreto ciclópeo (aguas abajo). / The objective of this research is to propose the use of a riverine defense wall with an LGD drainage system to comply with the technical considerations of the land and mitigate the economic - social impact caused by the overflow of the Rímac River, in the stretch of study from the Hanging Bridge located on Av. Arequipa to the Estela Montti Bridge, in the city of Chosica. Over the years, the human settlement, Clorinda Málaga, which resides near the bank of the Rímac River has been constantly affected by the overflowing of the Rímac River, generating great human and material losses. Currently, the District Municipality of Chosica has preventive measures against these flood phenomena, but they are not very efficient and do not generate security, since they are temporary solutions. To achieve the proposed objective, the following previous studies were carried out: Vulnerability and risk assessment; Flood risk analysis; Hydrological and Hydraulic Study and Software Modeling. Then, conventional and unconventional riparian defense walls were designed and budgeted, in order to evaluate them based on their efficiency, technical factors and cost / benefit. As a result, the proposed wall design cannot be selected for its execution, since the width of its foundation exceeds what is allowed by the technical considerations of the terrain. For this reason, it is recommended to execute a reinforced concrete wall (upstream) and cyclopean concrete wall (downstream) for the critical areas of the section under study. / Tesis

Les vallées tunnels sont les structures de drainage d'eau de fonte les plus imposantes de l'environnement sous-glaciaire. L'inaccessibilité des milieux sous-glaciaires actuels limitent nos connaissances des mécanismes impliqués dans leurs formations, des paramètres contrôlant leur morphologie et de leurs influences sur la dynamique glaciaire. Ce travail présente une nouvelle approche expérimentale visant à mieux contraindre la formation et le fonctionnement des systèmes de vallées tunnels. Cette approche repose sur le développement d'un nouveau dispositif expérimental simulant la circulation d'eau pressurisée au sein d'un substrat poreux et perméable sous une couverture visqueuse. Les résultats des expériences menées avec ce dispositif ont permis de déterminer des relations étroites entre les paramètres du substrat et les modalités de l'écoulement d'eau sur la formation et la morphologie des vallées tunnels. Les résultats issus des expériences démontrent que ce dispositif permet de recréer des systèmes de vallées tunnels. L'étude de ces vallées expérimentales suggèrent que la topographie du substrat et la production d'eau de fonte joue un rôle primordial sur la genèse des vallées tunnels et sur leurs morphologies. Deux morphotypes de vallées tunnels ont pu être identifiés avec des morphologies et des mécanismes de formation indépendants. L'analyse de la dynamique de la calotte sus-jacente a permis de mettre en évidence un lien étroit entre le développement des vallées tunnels et la dynamique des "ice streams". L'évolution de la capacité de drainage des vallées tunnels semble contrôler la dynamique glaciaire en régulant le flux de glace transitant dans les "ice streams". / Tunnel valleys are major components of the subglacial meltwater drainage system. The inaccessibility of modern subglacial environments reduces our knowledge on the mechanisms involved in tunnel valleys formation, the parameters controlling their morphology and their influence on ice-sheet dynamics. This work presents a new experimental approach aiming to better assess the processes of tunnel valleys development. This approach relies on the development of a new experimental device simulating a pressurized water flow within a porous and permeable substratum underneath a viscous layer simulating the ice-sheet. The main results of the experiments conducted with this device have demonstrated the influence of both substratum properties and meltwater drainage on tunnel valleys formation and morphology. Using the device, we first manage to reproduce tunnel valley systems experimentally. Analyses conducted on these valleys experimental valleys suggest that the substratum topography and meltwater production play a key role on tunnel valleys genesis and morphology. Two tunnel valleys morphotypes have been identified, each one being charaterized by a unique morphology and mechanism of formation. Monitoring of the experimental ice sheet during tunnel valley formation shows close relationship between tunnel valleys development and "ice streams" dynamics. The evolution of tunnel valley drainage capacity seems to have a strong influence on ice sheet stability by regulating ice flux within "ice stream corridors".

This study aimed to investigate the course of the nasolacrimal drainage system in three different brachycephalic dog breeds in comparison to normocephalic dogs and to draw conclusions on potentially adverse consequences for the drainage function. A computed tomographic-dacryocystography (CT-DCG) was performed in 51 brachycephalic dogs, consisting of 23 Pugs, 18 French and 10 English bulldogs. Six normocephalic dogs of different breeds and body size served as a comparison. Two- and three dimensional images were obtained and evaluated. Several parameters (length, angulation, gradient) were used to describe the nasolacrimal drainage system and to quantify distinctions between different breeds. Furthermore several additional characteristics were analysed, including the relative position of lacrimal foramen and nasolacrimal ostium, crossing of the nasolacrimal duct below the root of the upper canine tooth, the patency of the lacrimal drainage system and the presence of an accessory opening. While the length of the nasolacrimal duct is substantially reduced in brachycephalic dogs, their lacrimal canaliculi have much larger dimensions than those of normocephalic dogs. Additionally varying parts of the nasolacrimal drainage system follow an inverse direction in short-headed dogs, giving the entire nasolacrimal apparatus a characteristic U- or V-shaped appearance. The nasolacrimal duct exhibits a much steeper alignment in brachycephalic dogs compared to normocephalic ones. This strong slope however does not interfere with drainage function because of a consistently present accessory opening, being the main or only outflow pathway in all brachycephalic dogs and hence facilitating proper tear drainage regardless of the steepness.
