  • Interpretation and Identification of Unexploded Aircraft Ammunition Sites
           from Reconnaissance Flight Images

    • Authors: Maria BUDAYOVÁ, Karla SRNOVÁ, Jiří POSPÍŠIL, Václav ŠAFÁŘ
      Pages: 1–15 - 1–15
      Abstract: This article describes the optimal work sequence for the interpretation and identification of unexploded aircraft ammunition sites from reconnaissance flight images of the area bombed during World War II. The described activities are based on a number of previous actions that were carried out within the framework of the MVČR security research project entitled "The search for unexploded aircraft ammunition from World War II". Two sites in the Czech Republic were selected for the project solution, which are among the most affected ones by the World War II bombing. With regard to the current knowledge and experience of the research team, a procedure of activities was suggested in order to secure the optimal quality of the results of interpretation and identification of the sites where unexploded aircraft ammunition can be found. The results may be affected by the frequency and quality of reconnaissance flight images and the information on the used aircraft ammunition. The quality of the results also depends on the quality of previous work in the creation of an orthophoto, personal experience and knowledge of the people working on the interpretation and identification of the images. Keywords: Bombing; Interpretation and identification procedure; Orthophoto image; Stereoscopic evaluation; Unexploded aircraft ammunition.

  • Extracts of Cement Composites Based on Recycled Glass

    • Authors: Kateřina MÁČALOVÁ, Jakub CHARVÁT, Vojtěch VÁCLAVÍK, Tomáš DVORSKÝ
      Pages: 16–2 - 16–2
      Abstract: This article presents the results of extracts of recycled photovoltaic glass and cement composites, in which 100 % of natural aggregates were replaced with recycled photovoltaic glass in various fractions. Test specimens in the shape of a cylinder with a diameter and height of 40 x 40 mm were prepared according to the designed recipes R1 to R5. The R0 recipe was a comparative one without the replacement of natural aggregates. The test specimens were stored in a water bath for 28 days. The test specimens together with the recycled glass fr. 0/10 mm were subsequently subjected to extract tests according to Decree No. 294/2005 Coll. The incorporation of photovoltaic glass into the cement matrix has significantly reduced the content of selenium, molybdenum and cadmium. The concentrations of these toxic metals were reduced by 98.5 % in case of selenium, by 88.9 % in case of cadmium, and by 97.5 % in case of molybdenum. Keywords: Cement; Glass; Photovoltaic panel; Recycling; Secondary raw material.

  • Utilization of Augmented and Virtual Reality in Geoscience

    • Authors: Věroslav HOLUŠA, Filip BENEŠ, Michal VANĚK
      Pages: 22–3 - 22–3
      Abstract: In today's age of modern IT technologies, it is no wonder that modern visualization tools and techniques are finding their way into areas such as geological and environmental sciences. The market offers a wide range of software resources for use and especially for the creation of scenes in virtual reality. The aim of our article is to evaluate a number of tools for creating VR content and evaluate their practical applicability. In the experiments, several tools for creating virtual reality scenes were tested and these tools were compared in terms of their parameters. The conclusion of the article shows the results, while Photomodeler and RealityCapture were the most suitable software for the academic sphere. On the contrary, Bentley ContextCapture software seems the least suitable. Keywords: Augmented reality; Benchmarking; Geoscience; Virtual reality.

  • Chemostratigraphic Architecture of Sandstone Facies Exposed along
           Auchi-Ighara Road, Mid-Western Nigeria

    • Authors: Phillips Reuben IKHANE, Odunayo Christy ATEWOLARA-ODULE, Olalekan Olayiwola OYEBOLU, Omotoso Richard FAKOLADE
      Pages: 33–4 - 33–4
      Abstract: In this work, inorganic whole-rock geochemistry was applied to characterize the exposed sandstone facies along the Auchi-Ighara road Anambra basin Midwestern, Nigeria for distinction and correlation of the depositional units on the basis of the stratigraphic variation of geochemical trait. Fourteen representative samples collected from the outcrop were analyzed using Inductively Coupled Plasma-Mass Spectrometer (ICP-MS). From our analyses, ten major elements oxides, sixteen trace elements, and thirteen rare earth elements were obtained. The concentration of major elements in the samples range from 0.13 % and 53.71 % with SiO2, TiO2, Al2O3 and Fe2O3 being predominant. Other oxides found in the samples include K2O, CaO, Na2O, MgO and P2O5 indicating a recycled orogenic source of the grits from which the sandstone is derived. Trace elements concentration ranges between 0.017 ppm and 122.25 ppm; marked by the dominance of Zircon (Zr) which further asseverates orogenic recycling. The rare earth elements range in concentration from 0.01ppm and 5.53 ppm; the modal occurrence of Praseodymium (Pr) in this category is apparently indicative of deposition in an oxidizing environment. The appreciably high SiO2/Al2O3 ratio averages 11.2 in the samples is symptomatic of several cycles of sedimentation. Variation pattern of Ga/Rb and Al2O3/(CaO+MgO+K2O+Na2O) ratios connote a cooler and drier climatic condition after the sandstone deposition, which expectedly resulted to a decrease in hydrolytic weathering. Changes in sediment provenance are predicated on Cr/Al2O3, Cr/Na2O and Nb/Al2O3 ratio which indicate grits derivation from a more quartzose sedimentary and felsic sources that resulted from fluctuating paleoclimate during deposition. From the geochemical data, the paleoclimate and provenance of the sandstone facies were modelled and used for subdivision and correlation into two geochemical packages and five geochemical units. Keywords: Chemostratigraphy; Paleoclimate; Provenance; Weathering; Whole rock geochemistry.

  • Integrated Resistivity, Index, and Strength Characteristics of Subgrade
           Soils: Implication for Highway Pavement Failure Studies in North-Central

    • Authors: Daniel Opemipo OBASAJU, Moroof Olasunbo OLORUNTOLA, Sunday OLADELE
      Pages: 46–5 - 46–5
      Abstract: Integrated geophysical and geotechnical studies have been carried out to determine the geological cause(s) of the failure of sections of Ajaokuta – Anyigba Highway, North-central Nigeria. Forty-eight (48) Vertical Electrical Soundings (VES) were conducted on failed and stable sections of the highway. Also, twenty-one (21) subgrade soil samples close to VES stations from the unstable and stable sections of the highway were subjected to laboratory geotechnical analyses which include grain size distribution, Atterberg limits, compaction (Optimum Moisture Content, OMC, and Maximum Dry Density, MDD) and California bearing ratio (CBR) at soaked and unsoaked states following American Society for Testing and Material (ASTM) standards as appropriate. The geophysical results show that low resistivity (10–100 Ohms-m) inferred as clay/silt of low competence characterizes the subgrade soils of the unstable segment. While higher resistivity (148–272 Ohms-m) interpreted as sandy-clay/silt with moderate competence was obtained for the subgrade soils of the stable segment. Results of Geotechnical tests show that the subgrade soils of the unstable segment have geotechnical properties that generally fall below required standard specifications. Strong correlations of R = 0.86, 0.9, and –0.88 were obtained between CBR and sand, resistivity, and the amounts of fines, while a fairly strong correlation of R = –0.67 was obtained for the plasticity index. The high level of correlation implies that CBR can be predicted from geophysical data and other geotechnical parameters. The study has revealed that the advanced weathering of the underlying Mica-Schist to clayey/silty subgrades with unsuitable geophysical and geotechnical properties is a major contributor to the instability of the highway. Keywords: Atterberg limit; CBR; Grain size distribution; Resistivity; Subgrade soil.

  • Investigation of Forced-Air Duct Leakage Phenomenon Using CFD Methods for
           Underground Tunnel Construction

    • Authors: Maciej KOSOWSKI, Pavel ZAPLETAL, Grzegorz PACH
      Pages: 58–6 - 58–6
      Abstract: Using CFD, the paper deals with a simulation of all phenomena related to forced-air duct fitted with a fan, with the emphasis on unit aerodynamic resistance and untight air ducts. We created a 3-dimentional model of the system including perforations simulating untightens in order to make a computation network. Boundary conditions were set and calculations made in ANSYS Fluent 19.1 programme. The computational results were assessed using conventional methods used in mining operations and compared with the measurement results of real air ducts in mine workings. CFD is suitable to simulate forced-air ducts and allows for their more precise design. Keywords: Auxiliary ventilation; CFD; Leaky forced-air duct; Tunnel construction.

  • Irrigation Water Impact on Soil Properties in Arid Oued-Souf Region,
           Southeast Algeria

    • Authors: Issam ZAIZ, Djamel BOUTOUTAOU
      Pages: 70–8 - 70–8
      Abstract: The perimeters of the Oued-Souf region are irrigated by salty water coming from the phreatic water and thus progressive salinization of the soil occurs. This study aims at a qualitative analysis of the evolution of the salinity in the soils irrigated by pivot irrigation for several years. For this, three plots were irrigated by pivots in each agricultural region. The choice of these 3 plots is justified by the number of years of their cultivation: plot 1 has been cultivated and irrigated for 2 years (2016–2017), plot 2 has been cultivated and irrigated for 5 years (2016–2020) were studied and compared to the controlled soil not irrigated. The irrigation is done by sprinkling with mineralized water from the phreatic water. The results obtained showed that the irrigation water is characterized by high salinity and low sodium adsorption ration (SAR). Sodium and chloride contents are excessive in sprinkler irrigation mode. The evolution of salinity in irrigated soils between 2 and 5 years was very significant compared to the control (non-irrigated). The salinity goes from 0.38 dS/m in the control site classified as low salinity to 1.54 dS/m in the cultivated site for the 5 years classified as high salinity soil. The geochemical facies at the three study regions after irrigation are sulfate-calcium. A significant correlation is observed between calcium and sulfate with electrical conductivity (EC), so the salinity of our soils is dominated by sulfate. These results are confirmed by statistical analysis of the data (PCA), which revealed that salinity is heavily influenced by Mg2+, Ca2+, SO42- in the topsoil. Keywords: Hydrochemical; Irrigation water; Oued-Souf area; Phreatic aquifer; Salinity; Soil; Statistical analysis.

  • Assessment of Soil Collapse and Subsurface Features Using Integrated
           Geophysical Methods in Bismayah Pumping Station, Southeast Baghdad, Iraq

    • Authors: Hussein A. AL-SAADY, Hussein H. KARIM, Firas H. AL-MENSHED
      Pages: 82–9 - 82–9
      Abstract: The Bismayah pumping station was exposed to differential subsidence in the near surface soil due to the dewatering process. The geophysical surveys via ground penetrating radar (GPR) and electrical resistivity imaging (ERI) were used to assess the subsidence in subsurface soils. Four profiles of ERI using Wenner-Schlumberger array and four lines of GPR using antenna 250 MHz were implemented around the pumping station. The results show many underground features that are interpreted as concrete slabs of the storm and sewage tanks. These features reflect high resistivity values on the ERT profiles and high amplitude reflections on the GPR lines. Moreover, the results revealed the existence of pipe leakage on the northern side of the station, which in turn showed a very distinctive shape and low resistivity values. However, the results do not present any evidence of the existence of soil subsidence in the area around the station area. Keywords: Bismayah pumping station; ERI; GPR; Integrated geophysical methods.

      Pages: 91–9 - 91–9
      Abstract: The Doi Canal and the Cho Dem and Ben Luc Rivers play the key roles in irrigation, navigation and ecological restoration. It is important to clearly identify the pollution, influencing factors, ecological risks and possible sources of heavy metals in the surface water of this river system. The surface water of 7 sampling sites was collected over 7 consecutive periods from April 2019 to October 2021. Each surface water sample was analyzed for 9 heavy metals including Fe, Mn, Cr, Zn, Cu, Pb, Cd, Ni, As. Sampling and sample handling techniques were performed based on the Standard Methods for the Examination of Water and Wastewater. Among all nine heavy metals examined in the study area, the concentrations of Fe (1.00 ¸ 5.06 mg/L) and Mn (0.14 ¸ 0.28 mg/L) were the highest and the concentrations of Cr, Cd and As were below the lower limit of detection. The results showed that the average Fe and Mn contents both exceeded the permissible thresholds of the National technical regulation on surface water quality (QCVN 08-MT: 2015/BTNMT). Additionally, the content of Fe, Mn, Zn, Cu, Pb, Ni did not meet the water quality standards for aquatic life (United State Environmental Protection Agency). Keywords: Distribution; Heavy metal pollution; River; Surface water; Water quality protection.

  • Biomonitoring of Post-Mine Environment Using Ruderal Plants

    • Authors: Kateřina KUČOVÁ
      Pages: 99–1 - 99–1
      Abstract: Ruderal plants that remove toxic metals by accumulating in their tissues are called accumulators. Such accumulators can be used for phytoremediation or phytomining. The use of plants for biomonitoring environmental pollution by a non-invasive monitoring method correlates the effects of anthropogenic factors and living organisms. The advantage is the early detection of changes in the environment, thanks to the rapid response of bioindicators, responding to changes in the habitat, for example, by creating deformations. At present, biomonitoring is one of the indispensable parts of nature and environmental protection. The following species were selected for research - Aster amellus L., Rosa canina L. and Paraleucobryum longifolium; the area of ​​interest was the post-mining area. The aim of the study was to verify the hyperaccumulation activity of ruderal plants on the thermally active dump pile Ema, in the district of Ostrava-Karviná, Czech Republic. The plant samples were taken in the places with the thermal activity and were compared as for the capacity of bioaccumulation of hazardous metals – Co, Mo, Cd, Pb, Cr, As, Ba, Sr in the plant tissues from different parts of the plants (root, stem, leaf, fruit). The results were compared with the collection of metals at sampling points. The highest ability to bioaccumulate was demonstrated by plants from the Bryophyta division. Keywords: Bioavailability; Ema dump pile; Hyperaccumulation; Plants; Toxic metals.
