The present paper is aimed to river water quality modelling. A numerical and an analytical model have been developed in order to predict the transport of pollutants in the Romanian Someº River. A novel approach for the analytical modelling offers the opportunity to use variable parameters along the river length. Space dependent model parameters have been… (More)
This article reviews the application of Geographic Information System (GIS) technology in the field of decision support systems for water management activities. These systems are particularly important in extreme, therefore dangerous, conditions like floods or draughts. The GIS concepts are contextually reviewed based on their use as spatial database for… (More)
This paper presents a detailed mathematical model (ADModel) for the transport of nutrients (nitrate; ammonium; soluble reactive phosphorus and organic phosphorus) under unsteady flow conditions in River Swale.
The paper is focused on the comparison of the reverse flow reactor (RFR) and of the counter-current reactor (CCR) operation, focusing the attention on the interaction between transport phenomena and chemical reactions, as well as on the analysis of the dynamic behavior. A heterogeneous mathematical model was used in order to investigate the performance of… (More)
