Remote Sensing for Agriculture, Ecosystems, and Hydrology XIV

2012

Introduction - This proceedings volume contains papers presented during the conference on Remote Sensing for Agriculture, Ecosystems, and Hydrology XIV. The conference was part of the 19th International Symposium on Remote Sensing sponsored by SPIE - The International Society for Optical Engineering. The symposium was held at the Edinburgh International Conference Centre, Edinburgh, United Kingdom, from 24th to 26th of September 2012. The conference is dedicated to providing rapid dissemination of scientific and technical information, and attracted scientists and professionals from throughout Europe, Africa, Asia, and the Americas. More than 30 oral and 30 poster presentations were given, c…

Planktothrix rubescens in freshwater reservoirs: The Sentinel-2 potentiality for mapping phycocyanin concentration

2012

In December 2006 blooms of Planktothrix rubescens were found in the Prizzi reservoir in Sicily. P. rubescens is sadly famous for producing microcystins (MC), which are harmful hepatotoxins. Recently (2006) P. rubescens has been found in the Pozzillo, Nicoletti, Ancipa, Prizzi and Garcia reservoirs. This paper compares the optical properties of the water of an infested reservoir and those of a clear water reservoir. Furthermore it evaluates an empirical method based on bands product to evaluate the phycocyanin cell density from MODIS, Landsat ETM+ and Sentinel-2 images. Spectroradiometric field campaigns were carried out in February/March 2008 to quantify the spectral transparencies of two w…

VALUTAZIONE DEI CARICHI INQUINANTI DI ORIGINE DIFFUSA E CONCENTRATA A SCALA DI BACINO: APPLICAZIONE A UN CASO DI STUDIO SICILIANO

2010

Obiettivo della ricerca è stata la predisposizione di un modello di tipo integrato a scala di bacino al fine di ricostruire la dinamica dei carichi inquinanti concentrati di origine civile e produttiva e dei carichi diffusi di origine agricola e zootecnica, in osservanza dei nuovi criteri di gestione dei corpi idrici superficiali introdotti dalle normative nazionale ed europea (Direttiva UE 2000/60, D.lgs. 152/2006). Il modello messo a punto è stato applicato al bacino del fiume Nocella, ubicato in Sicilia e ritenuto un idoneo banco di prova in quanto recapito di numerosi scarichi in forma concentrata e diffusa. I primi derivano in modo continuo dagli impianti di depurazione a servizio di d…

Modelling hydrology and water quality in a Mediterranean catchment

2010

In this study the SWAT model has been used in order to analyse and quantify pollution dynamics at basin scale depending on concentrated and diffuse sources. Nowadays, the receiving water bodies quality safeguarding is of growing importance due to the promulgation of recent laws as well as the growing sensitivity regarding the environment issues by the scientific and practitioner committee. Recently the EU 2000/60 (Water Framework Directive) makes the analysis of receiving water bodies even more complex by integrating the pollution in urban areas in a framework of the pollution sources at catchment scale. and making necessary further integration of environmental impacts associated with disch…

Experimental Sorting of Municipal-Like Waste in the Hospital “Civico”, Palermo (IT)

2013

An experiment of source sorting - based management of Health Care Waste (HCW) was carried out in 2011 in 4 Departments of the Public Hospital “Civico” (Palermo, IT), where the basic mandatory separation between hazardous and non-hazardous waste was already going on since year 2000.The experiment consisted in weighing every day for 15 days 4 predefined fractions collected in the Infirmaries (namely paper, plastics, glass and unsorted fraction), and the bags with unsorted waste from the patient’s stay room. Furthermore, in 1 of the 4 Departments also the boxes of Infectious Waste (IW) were weighed for a week.As a result a weighted average value of 0.56 kg of Municipal-like Waste (MLW) per bed…

A mathematical model for a sequential batch membrane bioreactor pilot plant

2016

A mathematical model to quantify the nitrogen removal for a membrane bioreactor (MBR) has been presented in this study. The model has been applied to a pilot plant having a pre-denitrification MBR scheme. The pilot plant was cyclically filled with real saline wastewater according to the fill-draw-batch operation. The model was calibrated by adopting a specific protocol based on extensive field dataset. The Standardized Regression Coefficient (SRC) method was adopted to select the most influential model factors to be calibrated. Results related to the SRC method have shown that model factors of the efficiency of backwashing and the biological factors affecting the soluble microbial products …

Frontiers in Wastewater Treatment and Modelling FICWTM 2017

2017

Today, multidisciplinary is a key to solving issues in the water field. The works in several International Water Association (IWA) Specialist Groups have demonstrated the importance of both innovative technologies and mathematical modelling, and that the exchange of scientific and technical information among researchers and practitioners involved in these fields is crucial for effectively advancing knowledge. Mathematical modelling has the advantage of allowing scenario analysis before designing the real plant in order to ensure an optimized system. To foster the multidisciplinary collaboration among different water specialists, the dialogue is a must in order to better share specific knowl…
