River-bed erosion due to changing boundary conditions: performance of a protective measure
2018
Abstract. Due to the introduction of man-made sediment barriers along a river, the amount of sediment load entering the downstream river reach is different to that leaving the reach, and erosion processes occur downstream of the barrier itself. Designers are often required to take into account the scouring process and to include adequate protective measures against the local scour. This paper addresses the performance of bio-engineering protective measures against the erosion process. In particular, a green carpet, realized with real flexible vegetation, has been used as the protective measure against erosion processes downstream of a rigid bed. Analyses are based on experimental work carri…
Generation of Natural Runoff Monthly Series at Ungauged Sites Using a Regional Regressive Model
2016
Many hydrologic applications require reliable estimates of runoff in river basins to face the widespread lack of data, both in time and in space. A regional method for the reconstruction of monthly runoff series is here developed and applied to Sicily (Italy). A simple modeling structure is adopted, consisting of a regression-based rainfall–runoff model with four model parameters, calibrated through a two-step procedure. Monthly runoff estimates are based on precipitation, temperature, and exploiting the autocorrelation with runoff at the previous month. Model parameters are assessed by specific regional equations as a function of easily measurable physical and climate basin descriptors. Th…
Optical Methods for River Monitoring: A Simulation-Based Approach to Explore Optimal Experimental Setup for LSPIV
2021
Recent advances in image-based methods for environmental monitoring are opening new frontiers for remote streamflow measurements in natural environments. Such techniques offer numerous advantages compared to traditional approaches. Despite the wide availability of cost-effective devices and software for image processing, these techniques are still rarely systematically implemented in practical applications, probably due to the lack of consistent operational protocols for both phases of images acquisition and processing. In this work, the optimal experimental setup for LSPIV based flow velocity measurements under different conditions is explored using the software PIVlab, investigating perfo…
Verification of IRRILAB Software Application for the Hydraulic Design of a Micro-Irrigation System by Using IRRIPRO for an Apple Farm in Sicily
2021
In recent years, many studies have been performed to develop simple and accurate methods to design micro-irrigation systems. However, most of these studies are based on numerical solutions that require a high number of iterations and attempts, without ensuring to maximize water use efficiency and energy-saving. Recently, the IRRILAB software, which is based on an analytical approach to optimally design rectangular micro-irrigation units, has been developed, providing the solution corresponding to the maximum energy-saving condition, for any slope of the laterals and of the manifold. One IRRILAB limitation is that, according to its theoretical basis, the rectangular planform geometry and uni…
Comparative Analysis of Spatial Interpolation Methods in the Mediterranean Area: Application to Temperature in Sicily
2015
An exhaustive comparison among different spatial interpolation algorithms was carried out in order to derive annual and monthly air temperature maps for Sicily (Italy). Deterministic, data-driven and geostatistics algorithms were used, in some cases adding the elevation information and other physiographic variables to improve the performance of interpolation techniques and the reconstruction of the air temperature field. The dataset is given by air temperature data coming from 84 stations spread around the island of Sicily. The interpolation algorithms were optimized by using a subset of the available dataset, while the remaining subset was used to validate the results in terms of the accur…
La educación en casa o homeschooling: la STC de 2 de diciembre de 2010
2011
[EN] This article analyses raising conflicts between children ́ education ́s right and freedom of education belonging to parents and tutors, according to the complex article 27 of Spanish Constitution, especially after the recent sentence of Constitucional Court dated from 2nd December 2010, all of this in relation with the possiblility of giving basic education not through compulsory education but homeschooling.
Multimodalidad e innovación metodológica en la enseñanza del inglés: el álbum ilustrado como recurso literario y visual para el desarrollo del conoci…
2020
Este artículo se centra en el proyecto de innovación 'Recursos multimodales y literacidad' (UV-SFPIE_GER18-952026) llevado a cabo en la Facultat de Magisteri de la Universitat de València durante los cursos 2017-18 y 2018-19. En consonancia con los retos de la sociedad digital del siglo XXI y con el enfoque de la pedagogía de las multiliteracidades para el desarrollo del conocimiento, proponemos la multimodalidad, y en especial, el álbum ilustrado, primero, como un recurso literario y estético clave para la formación integral de los futuros docentes de inglés como L2 y, segundo, como una plataforma interdisciplinar para la construcción de significados. Los resultados de la investigación cua…
«Aplegar» i «arribar» en el «Curial e Güelfa»: un parell sinonímic?
2008
In this brief study we will carefully analyze the uses of arribar and aplegar in mediaeval language from Curial e Güelfa. Our goal is to discover when and up to which extent both verbs, arribar and aplegar, share their meaning during the first half of the 15th century, in order to shed light on the current situation of Valencian. At the same time, we will contrast the datum of this anonymous text with former, later and contemporary works from the datum of Corpus Informatitzat del Català Antic (CICA: 2007).
Barcelona vista pels narradors del vuit-cents
2014
L’article s’ocupa de les representacions o imatges de la ciutat de Barcelona en la prosa literària catalana del segle xix, especialment en el quadre de costums i la novel·la, que s’examinen com a expressions de cultura urbana. Aquesta literatura, associada a un cert concepte de modernitat, avança flanquejada per l’historicisme i el ruralisme mitificadors dels escriptors lligats als ideals conservadors de la Renaixença. L’article dibuixa la trama de motius o de trets idiosincràtics urbans en la prosa destil·lada pels escriptors del vuit-cents, primer en llengua castellana i, a partir dels anys 60, en llengua catalana. Així, fa un recorregut per la Barcelona vella i la Barcelona nova, abans i…
Variació morfofonològica. Variants morfològiques
1998
Morphological variation can be considered to take place in two levels: on a superficial level of phonetic nature and on a deep level of phonological nature. This study addresses the deep level of morphological variation, of morphological variation strictly speaking. It focuses on the variations of the morphological variables, that is to say, on the actual realizations of morphological variation. There are two kinds of morphological variations: of formal and of grammatical nature. Formal morphological variations are those with a phonological representations in which morphological variation is present. These are existing morphological variations. Grammatical morphological variations are those…
