Ranking spatial interpolation techniques using a GIS-based DSS
General
A GIS-based Decision Support System (DSS) was developed to select the appropriate interpolation technique used in studying rainfall spatial variability. The DSS used the ArcView GIS platform by incorporating its spatial analysis capabilities, the programming language "AVENUE", and simple statistical...
Weathering of Lead in Fort Irwin Firing Range Soils
General
This paper investigates the physical and chemical transformation of metallic lead (Pb) in Ft. Irwin firing range soils. Soil samples were collected from berms of two small arms firing ranges, an active one and an abandoned one, located in the Mojave desert. Pb bullet fragments found in field samples...
Environmental Strategies of Polluting Industries
General
Citizen concerns about environmental management practices will usually lead to public attention and legislative proposals. This paper intends to assess the behaviour of potential environmental polluting industries. In order to accomplish this objective, a survey composed of twenty-five questions was...
Spatial and Temporal Distribution of Air Temperature in the Northern Hemisphere
General
In the present study, the spatial and temporal surface air temperature variability for the Northern Hemisphere has been examined, for the period 1900-1996. Factor Analysis has been applied to 5o Latitude x 10o Longitude grid box data covering the area from almost the equator to 70o N. These data are...
Nitrate pollution in the coastal aquifer system of the Korinthos Prefecture (Greece)
General
Over the last decades intensified agricultural production is applied in the northern coastal part of Korinthos Prefecture (Peloponnese, Greece). An aquifer system occurs in the recent basin deposits, which consists of unconsolidated material, namely sands, pebbles and fine clay to silty sand...
Environmental Performance of Thermosyphonic Domestic Solar Hot Water Systems under Different Climatic Conditions: A Case Study for Greece
General
Undoubtedly, sun is the cleanest energy source. Specific systems are needed however for the collection and transformation of solar energy and the manufacturing processes of such systems, as well as the production of the raw materials required, are associated with impacts to the environment. As a...
Risk Analysis for Environmental Hazards. The case of oil spills in Crete
General
In this paper a review of most recent practices in the field of Risk analysis are presented. Then the available data for oil spill incidents in the area of Crete covering the period 1995-1999 are analysed and discussed in detail. Risk analysis tables are produced in order to formulate the spatial...
Unexplained Relationships of Height-Diameter of Three Tree Species in a Tropical Forest.
General
Associations between bivariate variables relative to the unexplained relationships of height-Dbh (diameter at breast height) models were investigated. Seven permanent sample plots measuring 40m by 250m at Omo Forest Reserve were used to assess the relationships between height and diameter at breast...
Exploratory traffic noise measurements at five main streets of Thessaloniki, Greece
General
Although noise is a very common nuisance in Greek cities, information on actual noise levels in streets is sparse. Here, noise measurements at five main streets of Thessaloniki, Greece for about five weeks are presented. Ten minute, one hour and daily average noise levels were calculated. Traffic...
Application of artificial neural networks for flood forecasting.
General
In hydrology, as in a number of diverse fields, there has been an increasing use of Artificial Neural Networks (ANN) as black-box simplified models. This is mainly justified by their ability to model complex non-linear patterns; in addition they can self-adjust and produce a consistent response when...
