The use of phosphate slime or phosphate water in a Mediterranean region (Gafsa, Tunisia) was investigated through hydrologic modeling. The simulations were made using the Hydrus 1D software package for a typical soil in the area of Gafsa (Tunisia). Two main applications were examined: mixing the...

Maisiagala RADON type radioactive waste storage facility was commissioned in 1963 in a marshy, ecologically sensitive locality, where soluble radionuclides easily can penetrate and migrate with groundwater. To assure the requirements of radiation safety, the analysis of radionuclide leakage from the...

Salinity is a common problem in Greek islands, especially, during the summer period when the saltwater intrusion becomes more severe due to extensive over pumping. In the past few years, the industrial zone of the City of Herakleio in Crete appears to have an increasing water demand as result of the...

Two Integrated Surface water - Groundwater flow Models (ISGMs) have been developed at the National Technical University of Athens (NTUA), Greece and Cardiff University (CU), UK to investigate surface water-groundwater interactions. The models are based on physical processes and are capable of...

The direct assessment of denitrification suffers from a number of problems. A mass balance model is simple and widely accepted to calculate nitrogen (N) loss as a denitrification component. The objective of study was to estimate the potential N loss a denitrification from a tropical paddy in the...
