A partir de los resultados obtenidos en los ensayos previos realizados en la camara germinadora se constato la existencia de un alto grado de heterogeneidad en el plantel producido. Mediante el analisis de los diferentes elementos de control de los factores ambientales de que esta dotada la camara se pudo apreciar que la causa fundamental de la heterogeneidad del plantel era la falta de uniformidad del riego. A lo largo de un ano se han venido realizando diversos ensayos cuyo objetivo es tanto evaluar con la mayor profundidad posible cuales son las causas del mal comportamiento del sistema de riego, como buscar alternativas tecnicamente viables que doten a la camara germinadora de un sistema de riego altamente localizado lo suficientemente fiable. Se ha comprobado que, si bien el sistema de riego esta correctamente calculado, las boquillas empleadas no reunen las condiciones necesarias de uniformidad ni en el caudal que aportan, ni en la distribucion del agua que deberia ser la de cono lleno. En este momento se estan probando otros tipos de boquillas y otros sistemas de riego alternativos que permitan resolver el problema de la heterogeneidad en la distribucion del agua de riego.

Es un estudio para seleccionar el area mas favorable para la perforacion de pozos tubulares a fin de garantizar el abastecimiento de agua para riego en el terreno del INIA

Treballs Finals del Màster d’Energies Renovables i Sostenibilitat Energètica, Facultat de Física, Universitat de Barcelona, Curs: 2020-2021, Tutors: Cristian Fàbrega, Albert Casas | Desalination of seawater has become the most recurrent way to obtain fresh water. The climate changes that have recently occurred, plus the global overpopulation, have increased the need to find out new ways to obtain drinking water. Many technologies have been used to find a solution to remove dissolved salts in seawater, however, the most relevant technology nowadays is the desalination of seawater by Reverse Osmosis (SWRO). RO is a technique to obtain fresh water by passing seawater through a membrane at high pressure, this technique has been strongly promoted, considering the inclusion of renewable energies which change the source of traditional electricity generation by fuel to this type of renewable and sustainable energy. The Carrizal desalination project (La Guajira Colombia), is a plan with a social focus that seeks to bring drinking water to the indigenous Wayúu population, using electrical energy from a network-assisted system, implementing a main wind power source and a photovoltaic power source as backup. The technical and economic feasibility of the project will be the purpose of this document, identifying the necessary feed water, the energy required for production, the design of the generation systems and the integration with the electricity grid, as well as recognizing the implementation costs of each technology and the possible environmental impact

Water storage assessment is an important component of feasibility studies for prospective mining areas. As required by national mineral resources and environmental Acts, this may include assessment of both exploitable and sustainable storage; the former relates to the amount of groundwater stored within the exploitable aquifer depth and the latter is defined as the groundwater that can be sustainably extracted without producing unacceptable environmental and economic problems. A simplified method is proposed to assess the groundwater storage in a typical mine area, Tugela in South Africa. In the area, five aquifers (Natal Group, Coastal plain deposits, Basement aquifer, Ecca Group and Dwyka Group) have better harvest potential compared with others on the basis of borehole yield. The study area was divided into four subareas (A, B, C and F) based on proposed mining boundaries. Both exploitable and sustainable groundwater storage were estimated. The estimated exploitable groundwater storage for subareas A, B, C and F are 20.66, 5.78, 43.12, 36.90 Mm³, respectively, on the basis of current median exploitation depths of each aquifer or geological formation. The calculated sustainable groundwater storage for subareas A, B, C and F are 3.31, 0.89, 6.67 and 6.01 Mm³, respectively, with a total of 16.88 Mm³. Groundwater recharge of the subareas was also estimated for subareas A, B, C and F as 31.92, 11.44, 43.38 and 29.78 Mm³/annum, respectively, with a total of 116.53 Mm³/annum. The assessment method can be applied to other areas with similar hydrogeological settings with the available datasets.
