Opis:
The durability of roads is dependent on the proper screening of the variations in subsurface geological characteristics and conditions through geo-engineering investigations and good construction practices. In this study, electrical resistivity tomography (ERT) technique was used to investigate the subsurface defects and potential failures along the substrate of Etioro-Akoko highway, Ondo State, southwestern Nigeria. Results of the inverse model resistivity sections generated for the two investigated traverses showed four distinct subsurface layers. The shallow clayey topsoil, weathered layer, and partially weathered/fractured bedrock have resistivity values ranging from 4–150 ohm-m, 10–325 ohm-m, and 205–800 ohm-m, with thickness values of 0–2 m, 0.5–12.5 m, and less than few meters to > 24 m, respectively. The fresh bedrock is characterised by resistivity generally in excess of 1000 ohm-m. The bedrock mirrored gently to rapidly oscillating bedrock troughs and relatively inclined deep penetrating multiple fractures: F1–F’1, F2–F’2 and F3–F’3, with floater in-between the first two fractures. These delineated subsurface characteristic features were envisaged as potential threats to the pavement of the highway. Pavement failures in the area could be attributed to the incompetent clayey sub-base/substrate materials and the imposed stresses on the low load-bearing fractured bedrock and deep weathered troughs by heavy traffics. Anticipatory construction designs that included the use of competent sub-base materials and bridges for the failed segments and fractured zones along the highway, respectively, were recommended.

Opis:
Single Electrical Resistivity Tomography (ERT) survey was carried out in the Manor and Park Complex in Nowa Huta (Krakow Branice, Poland). It was applied at a small distance and parallel to the longer wall of a monumental building containing an empty 3 m deep basement. Analogue modelling was performed in order to recreate the field study at the proper scale. The laboratory set-up consisted of a water tank where electrodes were mounted to the particular plate, which rested on water surface. The basement model was made out of a non-conducting material. The default and robust inversions were tested and these variants were also considered with the use of numerical modelling. Laboratory experiments have confirmed that zones visible in the interpreted field section are caused by the influence of the building cellar located next to the survey line. Zones of this kind are additionally disturbed by the local geological structure. The experiment has pointed out, among others, that as the distance between the survey line and the underground body increases, the inversion results are still burdened by an object influence. Thus, similar situations can be verified with the use of analogue modelling presented in this paper or 3D numerical one.

Opis:
We describe the application of 2D ERT (electrical resistivity tomography) surveys to investigate the spatial complexity of fluvial deposits of the Wisła River valley in the eastern part of Kraków (southern Poland). All ERT survey lines were completed within the industrially influenced floodplain of the Wisła River at two research sites. Due to the transformation of the natural state of the environment through many years of industrial activity of the ArcelorMittal Kraków plant, some of the geomorphological elements analysed have been irretrievably transformed and hidden by anthropogenic accumulations such as waste landfills and engineering structures. Hence, many years of soil contamination have changed the primary resistivity characteristics of the subsurface. For this purpose, the measurement array applied combines standard arrays, i.e., Wenner-Schlumberger and Dipole-Dipole, which gave improved results (higher resolution) in comparison to the standard single array. The data interpretation method was supported by the calculation and visualization of the vertical and horizontal gradients of the interpreted resistivity within the resistivity sections. This approach allowed accurate determination of resistivity boundaries on the ERT resistivity sections and thus helped lithological interpretation of the fluvial deposits in the research area. The resistivity of water in a channel located within one of the analysed areas has impacted some of the research results. Furthermore, 2D ERT forward modeling was implemented to generate synthetic datasets. The synthetic data allowed investigation of the influence of groundwater contamination on the resistivity distribution within superficial layers, and also tested the ability of the 2D ERT model to recognize the detailed spatial distribution of palaeomeander (meander scar) infills. All methods have provided new information on the industrially influenced floodplain of the Wisła River in Kraków.

Opis:
The depletion of Zn-Pb ores in developed mining areas and the increase in metal prices have resulted in the need to search for new deposits which have not been exploited yet. A project of drilling new exploratory boreholes should be preceded by an interpretation of archival geological data. To obtain the most valuable information on the geological structure leading to its plausible interpretation, it seems to be purposeful and advisable to apply some geophysical methods that are reasonably cheap in comparison with others. The method of electrical resistivity tomography, which in this research uses two of many measurement protocols such as Schlumberger array and dipole-dipole array, is particularly useful. Computer interpretation of geophysical results allows a high resolution 2D and 3D geoelectrical model of rock mass to be created. The study was carried out using the multi-electrode Lund Imaging System manufactured by ABEM, Sweden. In order to evaluate the practical application of this method, Zawiercie Zn-Pb ore deposits were chosen as the area used in previous scientific research. Taking into account mineralization in its economic aspect, the deposits occur at relatively shallow depths of 50-120 m. In the investigated region, the Triassic carbonate formation overlays the Devonian rocks. The Keuper low-resistance clay, occurring on the surface, provides a very good electrical contact between an electrode and the soil. This is why there are favourable measurement conditions in this area. The boundaries between the Keuper, Devonian and Triassic formations are clearly noticeable in the resistivity cross-sections obtained. On the basis of the ERT results, it is possible to locate faulting zones as well as karst systems. One of the profiles clearly shows the occurrence of a low-resistance anomaly correlated with Zn-Pb mineralization, which was confirmed by borehole surveys. However, this early stage of the research with the use of the ERT method cannot unequivocally identify the ore body, particularly as it was conditioned by the limited depth of prospecting.

Wawel Hill
Opis:
The Electrical Resistivity Tomography (ERT) method was applied at the SW foot of the Wawel Hill was applied. The survey was carried out along five survey lines (P1-P5), 50 m long each. The Wenner alpha array with spacing a = 0.5 m, 1.0 m, 1.5 m, 2.0 m, 2.5 m, 4.0 m, 5.5 m, 7.5 m, and 10.0 m was used. The basic electrode spacing was 0.5 m. In apparent resistivity contours and sections we can distinguish two zones, which have noticeably different resistivity values. The low resistivity zone dominates in the deeper part of the section on all survey lines, especially on the profiles located in the close neighbourhood of the Vistula River. The relative high resistivity zone is probably the effect of complex local geology, as well as the influence of the limestone of the Wawel Hill. Based on ERT inversion results, three resistivity zones were distinguished. Then the probable lithological or/and anthropogenic character was assigned to them. The shallowest zone has the thickness of about 0.5 m and results probably from accumulation of weathered limestone fragments derived from the Wawel Hill. It may be that high resistivity zones have anthropogenic character. Below, a zone of water-bearing sands was recorded, which may result from redevelopment and reclamation of this area. Thickness of this zone increases towards the Vistula River. Another zone, which can be identified with limestone, was identified on survey lines P4 and P5. This could also be result of accumulation of the calcareous debris for the purpose of planation of the area. In order to generalize and simplify the characterization of the quaternary sediments, ID interpretation was made. The method allows us to estimate the depth of groundwater, which in that place is about 5 m.

Opis:
During the construction of a section of the S-7 Lubień – Rabka-Zdrój dual expressway, located in the area of the Carpathian flysch (Carpathian Flysch Belt, South Poland), damage to the embankment was observed, as well as cracks and depressions in the new pavement. An analysis of the geological and engineering conditions in the area of the road section under construction showed the existence of a complex tectonic structure of the flysch formations, a shallow groundwater table, and numerous landslides. In order to stabilize the road substrate, it was decided to carry out injections, and the locations of these injections were initially geotechnically tested. However, due to the high variability of the geological structure, the target method employed was electrical resistivity tomography (ERT), which performed the survey in two stages. In Stage I, the geoelectrical/geochemical structure of the near-surface zone was identified, and the probable causes of road damage were indicated. This stage was completed by performing the stabilization and sealing process of the ground with an injection mixture. In Stage II, studies were carried out to evaluate the effectiveness of the injection process. The ERT method effectively identified the shallow geological structure and, in particular, delineated the zone of strong fractures in the flysch and areas associated with faults. Using the electrical resistivity tomography method, it was also possible to determine the injection mixture’s approximate penetration depth and the loosening zone’s degree of filling.

Opis:
This article presents the results obtained from geophysical measurements as a supplement to and refinement of geological information obtained from engineering geological studies for the newly constructed highways. The research was conducted using two geophysical methods: Ground Conductivity Meters (GCM) and Electrical Resistivity Tomography (ERT). The above measurements were made on three research fields located along the planned express road S-19 (Kraśnik-Janów Lubelski section). These areas were selected due to the large amount of available archival data and varied geological conditions. The publication focuses primarily on the presentation of the results obtained using the very fast and extremely efficient GCM method. By processing GCM data, using Laterally Constrained Inversion (LCI) and Spatially Constrained Inversion (SCI) algorithms, the values ofelectrical resistivity of the surveyed centers were derived. The results are presented in the form of cross-sections and maps of electrical resistivity from different depths, which were collated and compared with the results from another geophysical method, ERT. These examples show that the use of inversion has a significant impact on the refinement of geological boundaries between layers of different electrical resistivities. Thanks to the correlation of geophysical data with boreholes and engineering geological probes, detailed models of the geological structure of the analyzed areas were elaborated, which are necessary for the selection of appropriate solutions for the construction and modernization of road infrastructure.

W artykule przedstawiono i omówiono wyniki rozpoznania pierwszego poziomu wodonośnego za pomocą metody tomografii elektrooporowej (ERT). Wybrano trzy poligony badawcze w obrębie Warszawy, o różnej budowie geologicznej i odmiennych warunkach hydrogeologicznych. Jeden poligon znajduje się w obrębie wysoczyzny polodowcowej na terenie Warszawy („Pole Mokotowskie”), a dwa pozostałe są położone w obrębie doliny rzeki Wisły („Józefów” i „Tarchomin”). Poligony umiejscowione w obrębie doliny rzeki charakteryzują się m.in. swobodnym poziomem zwierciadła wody, natomiast w obrębie poligonu na wysoczyźnie polodowcowej występuje poziom wodonośny pod ciśnieniem. Rezultaty wykonanych badań dowodzą, że poziom wód podziemnych wyraźnie zaznacza się w obrazie uzyskanym metodą ERT, ale nie zawsze daje precyzyjne wyniki. Dokładność jego wyznaczenia zależy od uziarnienia gruntów, ich kontrastu opornościowego, wilgotności, metody profilowania elektrycznego oraz od ukształtowania stropu osadów niskooporowych (Warszawa – iły plioceńskie).
The paper presents the results and interpretation of Electrical Resistivity Tomography (ERT) study of the first aquifer. The study was carried out in the Warsaw region on three selected test fields with different geological structure and hydrogeological conditions: two in the Wisla River valley (“Józefów” and “Tarchomin”) and one in a postglacial upland in Warsaw (“Pole Mokotowskie”). The river valley aquifers are unconfined, whereas in the upland, the first aquifer is confined and under pressure. The results clearly show the presence of aquifers on the ERT image, but the positioning of the water level is not always precise. The precision depends on granulometry of sediments, resistivity contrasts, chosen method of resistivity measurement and morphology of low-resistivity sediments (e.g. Pliocene clays in the Warsaw area).

W pracy przedstawiono wyniki badań modelowych i geofizycznych z obszaru wyspy Wolin. Wyniki obliczeń numerycznego modelu filtracji wykazały, że zasilanie wód podziemnych zachodzi głównie w północnej i centralnej części wyspy, zgodnie z wyniesieniem Pasma Wolińskiego (góra Grzywacz – 116 m n.p.m.). Układ krążenia jest dostosowany do bazy drenażu, którą stanowią: na północy Morze Bałtyckie, na wschodzie rzeka Dziwna, na zachodzie Świna, a na południu Zalew Szczeciński. Dopływ do obszaru badań jest lokalnie formowany w wyniku infiltracji wód powierzchniowych, co może mieć miejsce zwłaszcza w rejonach funkcjonowania dużych ujęć. Największa eksploatacja dotyczy rejonu Międzyzdrojów i Wolina oraz dwóch ujęć dla Świnoujścia w zachodniej części wyspy. Właśnie w zachodniej części wyspy (rejon ujęcia Odra) zachodzi infiltracja wód powierzchniowych z Zalewu Szczecińskiego/ Świny. Na podstawie przeprowadzonych badań elektrooporowych zlokalizowano strefy ascenzji i ingresji wód o podwyższonej mineralizacji. Zmniejszający się pobór wód podziemnych na tym obszarze w ostatnich kilkunastu latach oraz racjonalna gospodarka wodami słodkimi zmniejszyły stopień zagrożenia dopływem wód słonych w wyniku ingresji i ascenzji.
This paper presents the results of geophysical investigations and groundwater modelling from the Wolin Island. The simulation results of the numerical model have shown that groundwater recharge occurs mainly in the northern and central parts of the island (Mt. Grzywacz – 116 m a.s.l). The groundwater flow system is adapted to the base level of groundwater drainage, which is: Baltic Sea in the north, Dziwna River in the east, Świna River in the west, and the Szczecin Lagoon in the south. Inflow to the research area is locally formed as a result of infiltration of surface water, which may take place especially in the areas of operation of major groundwater intakes. The major water intakes are located in Międzyzdroje and Wolin, and additional two in the western part of the Wolin Island for supplying the town of Świnoujście. Just in this extreme western part of the island – within the area of groundwater intake Odra, surface water infiltrates into the shallow aquifer from the Szczecin Lagoon and Świna River. Based on the geoelectrical imaging there was located a salt water intrusion and ascension of highly mineralized water. A decrease in consumption of groundwater in this area in recent years and the rational management of freshwater resources reduced the level of risk as a result of ingression and ascension of saline water.

Opis:
Ukraine is characterised by active natural hazards processes within different structural, tectonic and landscape zones. In Middle Dnieper basin region mass movement processes have great impact on people’s livelihoods and infrastructure. These processes occur on the slopes with different geological structure. The determining causes include lithologic and stratigraphic conditions, hydrogeological regime, structural and textural peculiarities of rocks and the geomorphology of the slopes. Landslide inventory database has been developed based on long-term observations of more than 400 landslides and landslide-prone areas. This paper takes efforts forward by combining different geological and geophysical methods to advance the current understanding of landslide phenomena and contributing towards a better informed assessment of landslide hazard and risk. The developed methodology is implemented in a test sites of Kyiv region, covering an area of 18.3 km2 situated in the Middle Dnieper basin. Electrical Resistivity Tomography, Self-Potential and Infrared Thermography techniques were employed to investigate the lithostratigraphic sequences, the geometry of landslide body and potential mass movement. The results presented here confirm the potential of using an integrated approach that combines different field data to better plan mitigation activities and measures for the effective land management. This study will be useful in increasing the safety aspects of the infrastructures and lives and also for planning of research and developmental activities.

Opis:
The spring floods in 2010 and 2014 yr have caused many weaknesses and interrupts of embankments. Especially a flood from 2010 was the greatest cataclysm written down within a dozen or so years in Poland. Financial losses arising from her reason are huge and amount to a few billion zlotys. The considerable part of these losses is associated with flooding areas located in valleys of rivers as a result of the break flood banks. The embankments which were to protect floodplains in many cases did not fulfil their role. In the article results of geophysical investigation using electrical resistivity tomography of chosen fragments of flood banks from Warsaw and surroundings is presented. The research was conducted in two areas of Vistula river valley. The first area included the fragment of embankment alongWa³Miedzeszyñski street in the area of Fieldorf street (Warsaw district Goc³aw). The other fragment of flood bank was in surroundings of Dziekanowskie Lake in Warsaw suburb £omianki.
