Overland flow is highly affected by increasing urbanization, and variations in land use and climatic variables, especially in the last few decades. This necessitates the development of modeling approaches for planning and management of catchments that play a significant role on water supply. The...

Different land uses, infrastructures, industrial activities and residential patterns of developed cities expose simultaneously people to several annoying sources. Over recent years, the European Union has provided several tools to harmonize noise mapping methodologies and relative Noise Action Plans...

Assessment of aridity conditions prevailing in a certain area is essential for the research on climate and climate change. Greece is characterized by a variety of climatic conditions such as drought conditions or flooding phenomena. The current study focuses on three selected areas within Greece...

Having developed rapidly in recent years, Konya, one of Turkey’s most significant industrial cities, has been hosting production activities in sectors such as glass, chemistry, mining, metal and machine in the factories 96% of which located in the third Organized Industrial Zone. In common...

The present study associates groundwater nitrate pollution with agricultural activity in the Upper-Cheliff wich is known for intensive farming practices. The indicatory kriging method is used in order to elaborate a map of the spatial probability distribution of nitrate concentration that exceeds a...

The Hydrologic Simulation Program-FORTRAN (HSPF) model is widely used to develop management strategies for water resources and to evaluate the hydrologic effect of various management scenarios. The spatial resolution of the input data used to parameterize HSPF model may induce uncertainty in model...

Turkey is a developing country and has achieved impressive economic development in recent years. But this rapid growth has brought in many environmental problems in Turkish cities, such as air pollution, water pollution etc. In order to eliminate these problems, environmental performances of the...

In the present work the physically based distributed rainfall–runoff modeling system, MIKE SHE, is used to simulate the surface runoff at a semi-mountainous impermeable area of Tavronitis River basin in Crete-Greece. The objective of this surface flow model is to develop an appropriate irrigation...

Wadi Auranah is one of the potential wadis in respect of land use, located on the western shield (Hijaz escarpment) of Saudi Arabia. A spatio-temporal change assessment of this wadi (valley) was conducted with the help of landsat data. The results of the spectral analysis and NDVI for vegetation...

The objective of this study is to present an integrated stochastic approach for quantifying the risk of oil spill in marine waters and adjacent coasts. This was achieved via the effective cooperation between the National Technical University of Athens (NTUA) and the Bogazici University (BU) within...

The construction of large infrastructure projects such as highways, railroads, landfills, airports, harbours offers great social-economic opportunities for the development of a region; it is also mainly responsible for the deterioration of natural environment in the greater areas where these...

Rainfall indices and Standardized Precipitation Index (SPI) were obtained for Rajasthan State characterized as the most sensitive and vulnerable state in India. Daily rainfall data of 35 years (1971-2005) for 31 well-spread stations were used to generate critical area maps. From the analysis of...

This paper analyzes the potential contribution of electric vehicles in greenhouse gas (GHG) emissions reduction over the next decade following a simulation procedure. Emissions were assessed through a stepwise methodological approach at the transportation link level in the Hamilton Census...

The aim of this study is to deepening knowledge on the agricultural nitrogen cycle within the Veneto region (Northern Italy) by computing the Gross Nitrogen Balance (GNB) with highly geographical resolution. Spatialised maps of nitrogen input and output, created using the most detailed information...

In this paper soil conventional tillage (CT) in two adiacent on-farm sites, hilly and plain fields, was carried out in comparison with direct-seeding + fertilizing at very low water content. The quality and quantity of work were evaluated through machine performance, fossil-fuel energy requirements...

This study aims at modelling three-dimensional shoreline change rates using differential interferometric synthetic aperture radar (DInSAR) techinuqe. Neverthless, decorrelation plays significant role to control the accuracy of three dimensional object reconstruction using DInSAR. To solve this...

Determining peak flows for ungaged areas is difficult and involves high uncertainty. Advanced computer capabilities provided by geographical information systems and hydrologic modeling software are used for detailed determination of the parameters involved, both for simple methods as the rational...

The Soil Science Institute of Thessaloniki produces new digitized Soil Maps that provide a useful electronic database for the spatial representation of the soil variation within a region, based on in situ soil sampling, laboratory analyses, GIS techniques and plant nutrition mathematical models...

Vulnerability assessment and production of the risk map of the contamination is considered as a managerial significant technique in the conservation of Karstic water resources. Karst aquifers in semi-arid regions of the West of Iran with respect to the region’s natural conditions are prone to...

In this study the vertical ozone profiles during summertime (June to August) of the MOZAIC (Measurement of Ozone and Water Vapor by Airbus in Service Aircraft) Project over the eastern Mediterranean airports of Heraklion and Rhodes in the Aegean Sea, have been analyzed in order to identify the major...

The present paper aims to assess the effect of various additives on the compressive strength of inorganic polymers (geopolymers) synthesised using low Ca electric arc ferronickel slag and alkali activating solutions. The main operating parameters include pre-curing (48 hours), temperature (40 to 80...

The objective of this study was to determine whether the use of the co-regionalization of the distanceto- river topographic variable with the soil properties topsoil clay and sand can improve their mapping. The interpolation techniques: ordinary kriging, kriging combined with regression (two models)...
