Item type: Artículo , Access status: Abierto , Modelización hidrológica de la cuenca alta del río Nalón (Asturias) para la determinación de recurso disponible destinado al abastecimiento de agua potable(Universitat Politècnica de València, 2022-04-29) Fernández-Rodríguez, Jesús Miguel; Miralles-Rivera, María Cristina; Álvarez-Álvarez, Eduardo[EN] This article describes the studies carried out to assess the quality of the historical information on the inflow regime of the Nalón river and the hydraulic resource available in the Rioseco reservoir, the catchment point of the supply system for the central area of Asturias, since the reliability of the methodology that has historically been used to calculate the average daily flows of the intermediate basin between Tanes and Rioseco is questioned. To this end, starting from the available contributions in the Tanes reservoir (located 5 km upstream from Rioseco), whose regime is less altered, and the quality of the data is higher, TETIS software is used to calibrate and validate a hydrological model to determine the available water resources in the Rioseco reservoir, which are practically unregulated. The results obtained conclude that the historical information on the water resources provided by this intermediate basin is unreliable, and that it would be interesting to consider it in future studies aimed at determining the security of the supply system.Item type: Artículo , Access status: Abierto , La importancia de la temperatura del agua en las redes de abastecimiento(Universitat Politècnica de València, 2022-04-29) Díaz García, Sarai; González Pérez, Javier; Agencia Estatal de Investigación; Junta de Comunidades de Castilla-La Mancha[EN] Temperature affects the physical, chemical and biological processes involved in the transport of drinking water, conditioning its water quality. Different works have revealed the role of this variable in specific phenomena. At the same time, research has been carried out to characterize temperature behaviour in water supply systems and assess its modelling possibilities. All of them are independent contributions, but there is not a global and joint vision about the role of temperature in the behaviour of a water network, even though this variable is one of those that will be most affected by climate change. The aim of this work is to revise the importance of water temperature in the different processes that occur during water distribution and to compile what is known so far about temperature modelling in water supply systems. This literature review highlights the importance of thermal conditions in the different dynamics within a distribution network, detecting a need to improve knowledge about its behaviour. This is important not only to better understand water quality at present, but also to evaluate the potential complications that may arise in future climate change scenarios.Item type: Artículo , Access status: Abierto , Evaluación de las mediciones de lluvia en la Ciudad de México utilizando la red de disdrómetros y su comparación con respecto a la red de pluviómetros de balancín(Universitat Politècnica de València, 2022-04-29) Amaro-Loza, Alejandra; Pedrozo-Acuña, Adrián; Sánchez-Huerta, Alejandro; Sánchez-Vargas, Carlos; Vergara-Alcaraz, Erick A.; Consejo Nacional de Ciencia y Tecnología, México[EN] This work represents a contribution to the evaluation of the conditions of precipitation observation networks in an urban area, based on the comparison between a network of laser optical disdrometer (LOD) sensors and a network of tipping bucket rain gauges (TB) in Mexico City. In the methodology, 9 LOD stations and 16 TB stations were selected, which were compared in two ways: first,from the total accumulation of precipitation over three years and second, by storm events. The results indicate that the analysis by storm events is more representative than comparing the accumulated precipitation. The measurements are acceptable, as these were checked from linear correlations. It was also determined that the number of events and the distance between the stations contribute to the correlation of the measurements. It is desirable that the methodology can be applied in the periodic quality control of measurements (calibration) and be part of the good practices for the measurement of the urban hydrological cycle at the local level.Item type: Artículo , Access status: Abierto , SUDS-lineales para reducir el riesgo de inundación considerando escenarios de Cambio Climático(Universitat Politècnica de València, 2022-04-29) Olivares-Cerpa, Gonzalo; Russo, Beniamino; Martínez-Puentes, Montse; Bladé, Ernest; Sanz-Ramos, Marcos; Ajuntament de Barcelona[EN] Sustainable Urban Drainage Systems (SUDS) are a valid alternative to solve several urban drainage problems. Its application, generally isolated, is limited and may not be effective in solving the foreseeable increase in maximum precipitation intensities associated with Climate Change. This study analyzes, in the current situation and with projections of Climate Change, the potential benefits of applying permeable pavement in bike lanes, turning them into linear, continuous and diffuse drainage elements( SUDS-linear ). Using a coupled hydraulic-hydrological numerical model that incorporates the infiltration capacity of a permeable pavement, and analyzing two areas of the city of Barcelona with different hazard due to pluvial flooding, the global behavior of this kind of linear SUDS was evaluated considering current precipitation scenarios and the potential effects of Climate Change. The numerical results showed a potential reduction of 90% in runoff.
