Ecohydrological modelling of flow duration curve in Mediterranean river basins

2013

Abstract Flow duration curve provides an important synthesis of the relevant hydrological processes occurring at the basin scale, and, although it is typically obtained from field observations, different theoretical approaches finalized to its indirect reconstruction have been developed in recent years. In this study a recent ecohydrological model for the probabilistic characterization of base flows is tested through its application to a study catchment located in southern Italy, where long historical series of daily streamflow are available. The model, coupling soil moisture balance with a simplified scheme of the hydrological response of the basin, provides the daily flow duration curve. …

The CoSMOS L-band experiment in Southeast Australia

2007

The CoSMOS (Campaign for validating the Operation of the Soil Moisture and Ocean Salinity mission) campaign was conducted during November of 2005 in the Goulburn River Catchment, in SE Australia. The main objective of CoSMOS was to obtain a series of L-band measurements from the air in order to validate the L-band emission model that will be used by the SMOS (Soil Moisture and Ocean Salinity) ground segment processor. In addition, the campaign was designed to investigate open questions including the Sun-glint effect over land, the application of polarimetric measurements over land, and to clarify the importance of dew and interception for soil moisture retrievals. This paper summarises the …

Proposal for a computer-assisted analysis of lawful interceptions of communication

2016

This paper presents the potential for the analysis of texts when applied to interceptions carried out with the help of next-generation software. In order to do this, after a brief explanation of some of the main procedures, the article presents the results of an investigation into text data extracted from wiretapping and in-person conversations found in judicial documents. The amount of data, obtained through wiretapping and the use of bugs, has made it possible to gather important information about the dynamics that characterise how criminal organisations work. The use of wiretaps and bugs are, therefore, vital tools without which it would undoubtedly not have been possible to achieve the …

Parameterizing the "grassland" module in the multispecific model FlorSys

2013

EAEcolDurCT1; The multispecies model FlorSys can predict the effects of cropping systems on the dynamics of weed communities in annual crops ; however, it is not configured to predict the fate of weeds in permanent cover such as grasslands. We realized the simulation of a weed seed rain in controlled conditions to estimate the percentage of weed seeds intercepted by a grass cover. Parameters of this linear model will be used to develop a new sub model in FlorSys to be able to simulate weed dynamics in temporary grasslands. We used twelve weed species selected on the basis of specific morphological characteristics and observations made in the experimental set up of SOERE ACBB (Observatory En…

Measuring and Modelling Evaporation Losses from Wet Branches of Lemon Trees

2022

Evaporation losses of rainfall intercepted by canopies depend on many factors, including the temporal scale of observations. At the event scale, interception is a few millimetres, whereas at a larger temporal scale, the number of times that a canopy is filled by rainfall and then depleted can make the interception an important fraction of the rainfall depth. Recently, a simplified interception/evaporation model has been proposed, which considers a modified Merrian model to compute interception during wet spells and a simple power-law equation to model evaporation from wet canopy during dry spells. Modelling evaporation process at the sub hourly temporal scale required the two parameters of …

LA LUCHA CONTRA LA INMIGRACIÓN ILEGAL EN ITALIA.

2021

The paper is aimed at analysing procedural national and supranacional profiles concerning the fight against smuggling. Among investigative measures adopted, it is worth mentioning the interception of communications, a measure that poses several issues for its impact on fundamental rights.

Le tecniche investigative nel contrasto ai traffici di migranti, stupefacenti e sigarette

2019

The paper is aimed at analysing investigative techniques used in the fight against trafficking of migrants, drugs and tobaccos at national as well as at European level

Effects of canopy covering on yield and quality of ‘Nero d’Avola’ (Vitis vinifera L.) grown in hot-arid climate condition

The impact of climate change on grapevine ecophysiology and vineyard management is predicted to be a serious problem in the next years. In fact, it has an influence on the fruit-set, yield, and in modulating decoupling between technological and phenolic ripening. Thus, it is essential to identify costeffective and easy-to-implement solutions to deal with the issue. For this purpose, the present study aims to test different shade treatments (ST) applied directly to the canopy of ′Nero d’Avola′ cultivar (Vitis vinifera L.), trying to limit the excess of light and heat that, usually occur in hot-arid climate areas as in Sicily. Two ST were imposed during the 2020 vegetative season from fruit s…

Méta-modélisation de l’interception de la lumière dans un couvert cultures: adventices

2017

EAGESTAD DOCT INRA; Dans le modèle parcelle virtuelle de dynamique de la flore adventice, FLORSYS, 70% du temps de calcul est utilisé par le module 3D d’interception de la lumière dont dépend la compétition des cultures et des adventices pour la lumière et la croissance des plantes. Afin d’accélérer le calcul, nous avons utilisé une méthode pour méta-modéliser le module. Cette méthode permet aussi réaliser une analyse de sensibilité. La hauteur et la largeur des plantes ont été identifiées comme des variables primordiales pour prédire l’interception de la lumière par le couvert.
