Lithological Composition

Rice irrigation systems in Kazakhstan are located on river terraces and levees of the Syr Darya, Ile, and Karatal rivers’ basins. The geological structure and lithological composition of soils in the aeration zone is characterized by a wide variety, differing in soil fertility, mechanical composition, water and physical properties, water availability and salinity. Alluvial-meadow and takyr soils consist of light and heavy loam, sandy loam, and clay [1,2,3]. Melioration errors of the rice irrigation systems, built in the period from 60s to 80s of the last century, can be described by the fact that the Kubanskaya rice sowing map was built on all soils of river terraces and river banks, with the same parameters of irrigation and drainage, with the share of rice 57.5% and 63% [4]. At the rice irrigation systems, where the geological structure and lithological composition of the aeration zone soils correspond to the irrigation and drainage parameters of the Kubanskaya rice sowing map, the soil fertility and ameliorative status of irrigated land has remained high for many decades. The salt content in the 100 cm soil layer is 0.3-0.4%; in the autumn-winter period ground water is at a depth of 2.0-2.5 m, its mineralization is 5-7 g/l. During the rice irrigation period, ground water does not connect with the water of rice paddies, and the filtration of water from rice paddies is permitted and comprises 12 – 17 mm/day. Rice is grown without flow and discharge of water from rice paddies, the irrigation rate is 21,400 m3/ha, and the yield is 5.2 t/ha. At the rice irrigation systems, where the geological structure and lithological composition of the soil in the aeration zone does not correspond to the irrigation and drainage parameters of the Kubanskaya rice sowing map, the land is saline. During the rice irrigation period, the ground water connects with the water on the rice paddies. On these paddies, due to the convective diffusion of salts from the soil and from ground water, water salinity increases and reaches the critical threshold of toxicity of 2.5 g/l [5]. It is necessary to discharge water to reduce the salinity of water on the rice paddies, which is followed by flooding of water from the irrigation channel. The irrigation rate is 23,500 m3/ha, and the yield is 4.7 t/ha.

The measureable magnetic field intensity variation is then interpreted in the form of the distribution of the magnetic material below the surface, then used as the basis for the prediction of possible geological conditions observed. The iron ore deposits in the survei area are generally interpreted as a form of sediment that fills the rock cavities, especially in limestone cavities. This occurs due to the geological structure that gives space for the placement of mineralization of ore deposits in the side rock zone. The value of this magnetic anomaly is located in the west, the eastern, and also in the north part.  Keywords: Geomagnet Method, Iron Ore, Magnetic Properties, Magnetic Value, Magnetic Anomaly Value.

Abstract Chełmno is a town in the north-western part of the Chełmno Lakeland. It is one of few towns in Poland to have fully preserved its medieval defensive walls. Its touristic and natural environs make it a popular tourist destination. The town’s location near the escarpment of the Vistula valley mean that the preserved historical structures (including the defensive walls) are under threat. A few years ago a buttress became detached and two sections of the defensive walls collapsed. One part was rebuilt (the site where the studies were conducted), while the second part remains unrestored. Bricks are also progressively coming away. This situation may be the result of several factors, although the authors claim that the most important are the geological structure and the wall foundations (which are shallow, at a depth of 1-2 m, with the wall having been built up higher in the 16th century).

As ground water is the only water source, then there is utmost need for exploring ground water aquifer besides importing water from neighboring countries and imposing serve strains on the available ground water resources. The present work deals with the hydrogeology, hydro geophysics, hydro chemistry, ground water management and planning in Qatar Peninsula.. For this purpose, field trips were carried out to measure geo-electrical properties of the rock units composing the geologic successions, and to measure the depth of water and deduction of ground water level for selected and test wells tapping the already proved aquifers (Dammam, Rus, Umm er Radhuma aquifers). In addition, ground water samples from the chosen wells have been collected for chemical analysis. A brief description of the geology of Qatar is included in this work with special attention to the lithology of water bearing formations, and the impact of structure on the hydrogeological conditions. The study of subsurface geological conditions of Qatar Peninsula has been made through the interpretation of geo electrical surveying data. 19 vertical electrical soundings (VESes) were conducted in the area of study. The interpreted geo electric measurements were correlated with the available information of some boreholes. The study of the hydro chemical conditions of the ground water aquifers of Qatar is mainly based on the chemical analysis of water samples collected by the present author. Total dissolved solids (TDS), major cations, major anions (Na+, Cl-, Ca+2, SO4-2, Mg+2, CO3-2, HCO3-) and PH were determined. In addition, hydro chemical coefficients were calculated to identify the origin of ground water and the suitability of ground water for irrigation purposes.  The present study aims to: Identify the sub surface geological condition necessary for clarifying the hydrogeological conditions of Qatar Peninsula. And Studying the collective hydrogeological conditions of Qatar Peninsula in the light of new data and detailed information enabling the possibility of additional ground water resources and proposing hydrogeological map for Qatar. And Planning ground water resources with the aim of maximizing water utility in the light of ground water quantity and quality. The study of some area in north of Qatar state presents results of water geochemical analysis in aquifers, the change in water table and salinity in wells. Based on samples of water ranges between 1500-12000 ppm in salinity (TDS), water table ranges 35-200m in depth. This study makes the best useful way to use it for several fields according to many factors. Major anions and cations are useful indicators of geochemical and availability of water in aquifers, the suitable units for irrigation water and human uses range between 1000-5000 ppm, that problem effect on surface uses. Geological study shows the lithology, composition, thickness and structure of layers, which contain water. About three main aquifers in Qatar (Umm er Radahma aquifer Paleocene, Rus formation aquifer Eocene, Dammam formation aquifer Eocene). Geophysics methods support geological studies for detailed information about water table and extension of aquifer. Lithology and structure for aquifer in Qatar play important role in retention of water between layers. Main results for geochemical sample of water and mapping for water table between aquifers are important to consider in the interpretation data from aquifer, serving to remind us of the different uses underground water.

On the basis of engineering and design surveys of the building, engineering-geological and geophysical studies of the soils of the territory conducted by the article authors, as well as with due regard for the results of studies conducted on this territory by other authors, the features of the foundations, soils of their foundation and engineering-geological conditions of the territory of the Melnikov House are established. It is shown that the Melnikov house is located under complex engineering-geological conditions on the territory of high geological risk, in the zone of influence of tectonic disturbance. To the North of the area there is a zone of intersection of the observed disturbance with a larger disturbance that can have an impact on geological processes. To the North-East of the site of the Melnikov House, a sharp immersion of the roof of carbon deposits was revealed. It promotes groundwater seepage into limestone of the carbonate strata from overlying water-bearing sands and activation of processes of suffusion removal and sinkhole phenomena of the soil. The surveyed area is assessed as potentially karst-hazardous and adjacent to it from the North-East territory as karst-dangerous. In this regard any construction on the adjacent territory can provoke activation of sinkhole phenomena on the surface. The foundations of the building are basically in working condition. Existing defects can be eliminated during repair. The foundation soils mainly have sufficient bearing capacity. Areas of the base with bulk soil can be reinforced. However, when developing a project for the reconstruction of the building and its territory, it should be taken into account that the design of the Melnikov House does not provide for its operation on the loads at the formation of sinkholes.

AbstractIn deep tunnels with hydro-geological conditions, it is paramount to investigate the geological structure of the region before excavating a tunnel; otherwise, unanticipated accidents may cause serious damage and delay the project. The purpose of this study is to investigate the geological properties ahead of a tunnel face using electrical resistivity tomography (ERT) and tunnel seismic prediction (TSP) methods. During construction of the Nosoud Tunnel located in western Iran, ERT and TSP 303 methods were employed to predict geological conditions ahead of the tunnel face. In this article, the results of applying these methods are discussed. In this case, we have compared the results of the ERT method with those of the TSP 303 method. This work utilizes seismic methods and electrical tomography as two geophysical techniques are able to detect rock properties ahead of a tunnel face. This study shows that although the results of these two methods are in good agreement with each other, the results of TSP 303 are more accurate and higher quality. Also, we believe that using another geophysical method, in addition to TSP 303, could be helpful in making decisions in support of excavation, especially in complicated geological conditions.

AbstractThis study presents the first subglacial topography and ice thickness models of the largest ice caps of the Argentine Islands, Wilhelm Archipelago, West Antarctica. During this study, ground-penetrating radar was used to map the thickness and inner structure of the ice caps. Digital surface models of all studied islands were created from aerial images obtained with a small-sized unmanned aerial vehicle and used for the construction of subglacial topography models. Ice caps of the Argentine Islands cover ~50% of the land surface of the islands on average. The maximum thickness of only two islands (Galindez and Skua) exceeds 30 m, while the average thickness of all islands is only ~5 m. The maximum ice thickness reaches 35.3 m on Galindez Island. The ice thickness and glacier distribution are mainly governed by prevailing wind direction from the north. This has created the prominent narrow ice ridges on Uruguay and Irizar islands, which are not supported by topographic obstacles, as well as the elongated shape of other ice caps. The subglacial topography of the ice caps is undulated and mainly dependent on the geological structure and composition of magmatic rocks.

The Impact

The coastline of Western Pomerania has natural and cultural assets that have promoted the development of tourism, but also require additional measures to ensure the traditional features and characteristics are protected. This is to ensure that new developments conform to a more uniform set of spatial structures which are in line with the original culture. Today, seaside resorts are characterized by a rapid increase in development with a clear trend towards non-physiognomic architectural forms which continually expand and encroach on land closer to the coastline. This results in a blurring of the original concepts that characterized the founding seaside resort. This study evaluates 11 development projects (including a range of hotels, luxury residential buildings and hotel suites) built in 2009–2020 in the coastal area of Western Pomerania. An assessment of architecture-and-landscape integration for each development project was made, using four groups of evaluation criteria: aesthetic, socio-cultural, functional and locational factors. The study methodology included a historical and interpretative study (iconology, iconography, historiography) and an examination of architecture-and-landscape integration using a pre-prepared evaluation form. Each criterion was first assessed using both field surveys and desk research (including the analysis of construction plans and developer materials), and then compared with the original, traditional qualities of the town. This study demonstrates that it is possible to clearly identify the potential negative impact of tourism development on the cultural landscape of seaside resorts, and provides recommendations for future shaping, management and conservation of the landscape.
