Summary

Proper management of water resources plays a very important role in protecting the natural environment. Overexploitation of these water resources (surface and underground) causes a significant reduction in water reserves. It’s also well known that there are negative effects of temperature and rainfall have been observed worldwide in recent years. So, it is now necessary to simulate groundwater flows and mass transport for the effective protection, planning and management of water resources. In the present study simulation of the underground flow and mass transfer of nitrates was carried out in the alluvial basin of interest in the Municipality of Trizinia-Methana. The ground water flow calibration was performed using groundwater hydraulic ground data from 8 periods. In order to evaluate the model a statistical sensitivity analysis was applied. The Visual Modflow model was used for the simulation. Initially the geographical, geological and hydrological characteristics of the area of Troizinias were gathered and then the hydrological balance of the aquifer of the studied area was formulated. In conclusion, through the method of simulating the underground flow of an aquifer we have the possibility of an integrated planning of the optimal management of the water resources.
