This work involves the application of mathematical flow and transport models for groundwater in the study of an oil polluted site situated in the city of St. Petersburg. The study has been developed in three principal phases: • data collection and interpretation using Geographical Information Systems and database; • conceptual model elaboration using geostatistical analysis; • mathematical flow and transport model implementation. The flow model has been calibrated considering the different head v

The Taro River Hydrogeological Basin (TRHB) is a small fandelta and alluvial fan depositional systems water bearing stack included in the Quaternary Po River Basin and located in the Western Emilia-Romagna Region of Italy, between the margin of the Northern Apennines and the Po River. The thickness of the fresh water bearing, part of TRHB, ranges from a few meters to more than seven hundred meters. Almost 90 Mm3 of groundwater and 50 Mm3 of stream water are yearly subtracted from the TRHB to sustain economi

The aim of this paper is to identify a computer based methodology in order to draw up a lithostratigraphic 3D model of an aquifer so as to develop a groundwater flow model in a part of it, useful to define some parameters involved in the evaluation of the water balance. The methodology was applied in two sample areas located in the Sarno Plain (Italy) affected by strong groundwater subflow. The stratigraphical reconstruction of the study areas was obtained by interpolating stratigraphical data from analyz

A methodology for assessing the zenithal groundwater recharge was tested over an area of the Lombardy Plain between the rivers Ticino and Oglio (northern Italy). This estimation system is based on the use of the Macro numerical code (Jarvis, 1994) in simulation scenarios characterised by lithological profiles differing for the type of soil, thickness, geology of the unsaturated zone, climate conditions and farming practices. This methodology was previously tested on sample profiles in a portion of the Mila

This paper presents the latest results obtained by a numerical model of the groundwater circulation in the North Western Sahara Aquifer System (NWSAS). The aim was to obtain some realistic simulations of the piezometric downward trend and the decrease of local artesianism. On the basis of the experience acquired in the last few years in the framework of an intergovernmental cooperation project, it was possible to use a recent regional numerical model developed by the South Sahara Observatory. This model wa
