This paper won the Kriton Curi award for best conference paper. Abstract: The emission of offensive odour from landfill sites is a nuisance that generates public opposition to the existence of these facilities. The aim of our research is to develop technology for an...

Abstract: Odour emissions from landfill sites generate public opposition to the existence of landfills. Our research aims to develop technology for an effective management and decision support system for landfill operations that will minimise the negative impacts of...

Abstract: An “Odour Management System” (OMS) has been developed to generate graphical predictions of dilution of gas from emission sources on a “real-time” basis. Particular focus has been on odour from the open working face at landfills. An OMS has been implemented...

Executive Summary: What is this new version of the String of Beads Model? Weather radar measures rainfall rates over a large area in fine spatial detail and very frequently. This translates into a circular area up to 200km across with 1km resolution every 5 minutes....

Abstract: A stochastic space-time model of rainfall is proposed, which is defined by a small number of parameters and models rainfall intensity images measured by radar. It is a phenomenological (rather than a physically based) model which provides sequences of...

Abstract: The String of Beads model is a space-time model of rainfields measured by weather radar. It is here driven by two auto-regressive time series models, one at the image scale, the other at the pixel scale, to model the temporal correlation structure of the...

Executive Summary: What is the background to this research? A valuable measure of the country’s potentially available water resources is through rainfall measurements. These measurements help with the quantitative definition of drought and possible climatic change,...
