Spatial hedonic pricing models for the valuation of irrigation water
General
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
General
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
General
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
General
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...
Mediterranean's changing saltscapes; a study of the abandonment of salt-making business in Greece
General
Saltscapes are landscapes with a long lasting salt-making activity, thus embedded with a blend of salt-related characteristics that marked them physically, ecologically, economically, and culturally. This study, based on a broad survey, focuses on the changing atlas of saltmaking business and the...
The Ninth International Symposium on Salt and the Ecological Importance of Solar Saltworks
General
The Ninth International Symposium on Salt (www.worldsalt2009.com) organized by China National Salt Industry Corporation, China Salt Association and many other salt organizations of the world was held in the Beijing International Convention Center on the 4-7 September 2009. It is the ninth in a...
Biological pretreatment of municipal solid waste prior to landfilling
General
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
General
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
General
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...
Principal component analysis of precipitation in Thessaly region (Central Greece)
General
Characteristics of the precipitation pattern are determined for Thessaly region in central Greece by using the Principal Component Analysis (PCA). Mean monthly precipitation data from 75 meteorological stations are used covering a 35 year period (1960-1994). The first two principal components (PCs)...
