Spatial hedonic pricing models for the valuation of irrigation water


Mallios Z., Papageorgiou A., Latinopoulos D. and Latinopoulos P.


The main objective of this work is to apply the hedonic pricing method using the methodology of spatial econometrics in order to assess the economic value of irrigation water, as one of the individual attributes of the value of agricultural land parcels. Most of the agricultural land’s value...

Neural networks approached for modelling river suspended sediment concentration due to tropical storms


Wang Y-M., Kerh T. and Traore S.


Artificial neural networks are one of the advanced technologies employed in hydrology modelling. This paper investigates the potential of two algorithm networks, the feed forward backpropagation (BP) and generalized regression neural network (GRNN) in comparison with the classical regression for...

Disposal options for dredged marine sediments based on physicochemical and toxicological characterization


Katsiri A., Pantazidou M. , Damikouka I., Kontogiorgi Ch. and Tringali A.


This paper presents a methodology of evaluating management options for dredged sediments on the basis of an array of characterization tests and gives an example application for the sediments of Piraeus port. A conceptual model is proposed to guide selection among three management options. The model...

Determination of PAHs in marine sediments: analytical methods and environmental concerns


Nikolaou A., Kostopoulou M., Lofrano G. and Meric S.


Polycyclic Aromatic Hydrocarbons (PAHs) are one of the major categories of pollutants entering the marine environment and finally accumulating in the sediments. Their occurrence raises major concerns for human health, especially during coastal activities (bathing waters, aquaculture, etc), having...

Biological pretreatment of municipal solid waste prior to landfilling


Mahar R.B., Yue D., Liu J., Zhang Y. and Nie Y.


The conventional landfilling does not promote sustainable waste management due to uncontrolled emissions which potentially degrade the environment. In this regard, pre-treatment of municipal solid waste prior to landfilling significantly enhance waste stabilization and provides various advantages...

Optimization of the furrow irrigation efficiency


Ampas V. and Baltas E.


Furrow irrigation is used for row crops. S.C.S., based on a great number of field experiments, under different circumstances and soil families, has developed design equations for furrow irrigation. These equations have been used for steady flow rate or for flow rate with one reduction when the water...

Prediction and study of passive pollutant dispersion in a street-canyon in London using computational fluid dynamics techniques


Galani A., Neofytou P., Venetsanos A., Bartzis J. and Neville S.


Pollution levels in an urban street-canyon area are determined numerically as part of the European research project OSCAR using the ADREA-HF code. Aim of the modeling is twofold: (i) to investigate the flow-field and carbon monoxide (CO) concentrations in the area and (ii) compare with measurements...
