Nová koncepce velkoplošných závlahových systémů / New concept of large-area irrigation systems

Pírková, Marcela January 2021 (has links)
This diploma thesis is focused on a large-scale irrigation embedded in the urban landscape. The main goal is to find a new concept of the large-scale irrigation system using a minimum of added electrical energy. The system is aimed at rainwater harvesting and distribution in populated areas. Part of the work is the analysis of the zoning plan of the selected locality, the design of the entire system from the accumulation of collected water to the distribution of watering to the root zone of plants. In the practical part, the proposed distribution network is calculated according to the current known equations, and the calculation is finished with the choice of a suitable diameter of the pipeline network. In addition, the work suggests possible sites for new planting of plants.

On this paper, the methodologies for calculation of final volume of rainwater reservoir proposed by ABNT (2007) were used, as well the historical series of rainfall data and those projected for two possible climatic scenarios were used. Through the PGECLIMA_R tool, it was possible to project the precipitation levels predicted in the best and the worst climatic scenario by the end of the century, in order to size the reservoir and analyze the impacts caused by climate change under the final volume of the rainwater reservoir. It was concluded that the designer should take into account the expected climate changes for the design of storage reservoirs and the use of rainwater, since these presented large volume variations according to each applied methodology and for each simulated scenario. When designing future precipitation data, the PGECLIMA_R software presented itself as an important tool to be used in the area of civil construction, urban and development planning. / O objetivo deste estudo foi dimensionar o reservatório para águas pluviais para a Região dos Campos Gerais do Paraná de acordo com as metodologias propostas pela ABNT (2007), considerando para tanto os impactos das alterações climáticas projetadas até o final do século XXI do quinto relatório do IPCC. Para realização deste trabalho foram utilizadas as metodologias de cálculo de volume final de reservatório de água pluvial propostas pela ABNT (2007), série histórica de dados pluviométricos assim como os projetados para dois possíveis cenários climáticos. Através da ferramenta PGECLIMA_R foi possível projetar os níveis de precipitação previstos no melhor e no pior cenário climático para o final do século, e desta forma dimensionar o reservatório e analisar os impactos causados pelas alterações climáticas sob o volume final do reservatório para águas pluviais. Concluiu-se que os métodos de dimensionamento estudados possuem grande sensibilidade quanto às alterações climáticas, sendo assim o projetista deve levar em consideração as alterações climáticas previstas para proceder com o dimensionamento de reservatórios de armazenamento e utilização das águas pluviais, uma vez que estes apresentaram grandes variações de volume de acordo com cada metodologia aplicada e para cada cenário simulado. Ao projetar dados de precipitação futuros, o software PGECLIMA_R apresentou-se como uma importante ferramenta a ser utilizada na área da construção civil, de planejamento e desenvolvimento urbano.

Propuesta de implementación de un sistema complementario de abastecimiento de agua para uso sanitario proveniente de las aguas pluviales para cubrir los periodos de desabastecimiento del servicio de agua potable municipal SEMACEL, en la Institución Educativa Manuel de Piérola Castro del distrito de Celendín, departamento de Cajamarca / Proposal to implement a water supply system for sanitary use by using rainwater to compensate the periods of water shortages, from the municipal water service SEMACEL, at the Manuel de Pierola Castro educational institute located in Celendin, Cajamarca

El Perú es uno de los países con mayores reservas de agua dulce en el mundo, ocupando el octavo lugar con una reserva de 1.89% de la disponibilidad mundial de agua dulce superficial. Sin embargo, a pesar de que existe abundante oferta del recurso hídrico, las brechas de acceso al agua son cada vez mayores. Los pueblos de la sierra peruana, no son ajenos a esta realidad, ya que, no cuentan con un eficiente abastecimiento de agua. Frente a esta problemática, el objetivo de la presente investigación es proponer un sistema de abastecimiento de agua en la I.E. Manuel de Piérola Castro, aprovechando la alta precipitación del distrito de Celendín. Para ello, se visitó la zona de estudio para determinar la oferta hídrica pluvial, estimar la demanda de consumo de agua de la I.E. Manuel de Piérola Castro y conocer la realidad problemática del distrito de Celendín. En el distrito de Celendín se registra precipitaciones medias de 6.28 mm por día, equivalentes a 5.1 litros de agua por metro cuadrado de cubierta de captación, lo cual, representa una alta capacidad de aprovechamiento de agua de lluvias para uso sanitario. A su vez, la instalación del sistema de aprovechamiento propuesto resulta factible debido al bajo costo que este representa. Finalmente, se evidencia beneficios de utilizar agua de lluvia, puesto que, significarían un ahorro en el pago a la entidad administradora de agua potable, se garantiza la continuidad del servicio de agua y se contribuye al manejo sostenible de los recursos hídricos. / Peru is a country that has one of the largest freshwater reserves in the world with it ranking 8th globally with a reserve of 1.89% of the total global amount of surface freshwater in the world. However, despite the abundance of this resource, the gaps in access to water are increasing. This situation is common among people living in the Peruvian highlands because they don’t have access to freshwater. The objective of this current investigation is to propose the use of a water supply system at I.E. Manuel de Piérola Castro that takes advantage of the high amount of rainfall in the district of Celendín. To do this, the study area was visited in order to determine the rainwater supply, estimate the demand for water consumption at I.E. Manuel de Piérola Castro and learn about the problematic reality that the Celendín district is going through. In the district of Celendín, 6.28 mm of average rainfall is recorded per day, which is equivalent to 5.1 liters of water in one square meter of catchment cover. This demonstrates the potential of using rainwater for sanitary use as the catchment cover of the Educational Institution Manuel de Piérola Castro covers more than 1300 square meters. Additionally, the installation of the proposed harvesting system is feasible due to its low cost. Finally, there are many benefits to using the proposed system such as savings on bills to the drinking water administration entity, guaranteed continuity of water, and sustainable water mismanagement. / Tesis
