This research evaluated how modifying the conceptual model of a groundwater system affects simulated results. At the first stage, mathematical model of groundwater flow in Gdansk aquifer system was built. In the next stage, 3 analytical schemes resulting from aquifer aggregation were defined. Then the flows and groundwater balances were computed and compared to flows and balances computed in the overall model of the Gdańsk aquifer system.

This study describes the hydrological conditions of migration of potential pollutants to shallow groundwater in the Mogilnica River catchment, classified as a typically agricultural lowland catchment in Poland. The assessment of vulnerability of aquifers to the inflow of pollutants from the ground's surface was conducted with the use of the GOD rank method introduced by Foster, and the method of calculation of contamination migration time through the aeration zone according to the formula of Bachmat and Collin. Using the data collected in the geographic information system, digital (screen system) maps were prepared for the catchment, illustrating the spatial distribution of the analyzed parameters. There were identified zones with different degrees of groundwater resistance, including areas that, owing to hydrological conditions, are the most vulnerable to the inflow of pollution. The collected data sets were compared with information on the method of development and use of the catchment, which was the basis for classification of the scale of hazard for groundwater from existing and potential anthropogenic activity.

The results of a magnetic study of the Okenugbo Area of Ago-Iwoye, Southwestern Nigeria are presented for the evaluation of the geostructural settings in the area to determine the competency of the basement for building constructions. The study area lies within Longitude N - N and Latitude E and E in the basement complex of Nigeria. Three magnetic profiles were established for the evaluation and the magnetic anomaly map, the regional geology and its analytic signal amplitude helped in identifying the nature and depth of the magnetic sources in the study region. The magnetic residual values range from -2400 nT to +1800 nT. The area shows magnetic closures of various sizes at the Western part of the study area trending West with prominence at the center and distributed East-West which has been interpreted as fractured or faulted zones. The depth estimate revealed the apparent depth to the causative body from the surface and the basement depth range from 4.3 to 21.3 m which agrees with other literatures. The study has revealed that the area is generally competent for high rise structures and industrial site while the faulted/fractured zones are prospective better locations for hydrogeological purposes.

The study area is located in the southern part of the Warsaw city agglomeration, adjacent to the Chojnowski Landscape Park. The study area is situated in the boundary zone between: (1) the bottom of the river valley reach with peat cover and (2) the Pleistocene glaciofl uvial plain on its lower level. The main aim of the study is the analysis of the investment impact on hydrogeological conditions. During the preconstruction site works on the bottom of the valley it was an earthwork constructed in order to extend the zone of the buildings in the valley area. The research method consists of fi eld works (geological drillings, piezometers constructions and observations, geodetic measurements), as well as laboratory works (sieve analysis) and hydrodynamic modelling (Visual MODFLOW, version 2009.1). The hydrogeological model performed in the study seems to became a base for the concept of the restoration of groundwater conditions.
