ABSTRACT: The need for drinking, use, energy and water for many purposes is increasing day by day as a source oflife for all living things. Unplanned use of water resources is one of the most important problems today. Due tooveruse, water resources are adversely affected and polluted by environmental factors. The management of waterresources in this framework is important not only in terms of water quantity but also in terms of its quality. Inthis study, hydrochemical properties of water samples taken from 17 different points in Trabzon city Söğütlü Riverand its branches were determined and the basin was classified in terms of different water quality parameters byusing spatial analysis techniques. Dissolved oxygen (DO) values at Söğütlü Stream ranged from 2.76 to 11.24 mg/l;Hardness values (FS) vary between 50.75-218.48 mg/l. pH value in surface water is between 6.63 and 7.5; theelectrical conductivity (EC) value is between 61-258 μS/cm and the total dissolved solids (TDS) is between 58-223 mg/l. Surface water of Söğütlü Stream classified as Fe, Mn and Al is in II., III. and IV category according toClassifications of Inland Surface Water Resources. In terms of NO2 and NO3 pollution parameters, also water class is in II., III. and IV. category. Physical, chemical and pollution analyses made on the surface water of SöğütlüRiver show that surface water has been polluted in recent years due to unfavorable environmental conditions.

ABSTRACT: In this study, it was aimed to determine the structural discontinuities of the Cyprus Island by applying totalhorizontal derivative and tilt angle techniques to the vertical first derivative data of satellite gravity data. Whendetermining the structural discontinuities of the zone, the maximum amplitudes of the total horizontal derivativemap and the zero amplitude values of the tilt angle map were utilized. The specified lineaments are comparedwith known discontinuities in the study area. Along with a good harmony between this study and previous studies,new discontinuity boundaries were determined. In addition, the basement topography of the Cyprus Island iscalculated by using the Parker-Oldenburg inversion algorithm. It is believed that the study will contribute to a betterunderstanding of the geological structure of the region.

ABSTRACT: In recent years, transportation tunnels have been excavated by mechanical methods. The selection of a suitableexcavator for the geological structure is an important factor in achieving an efficient tunnel excavation. For thispurpose, geological formations along the Kabataş-Mecidiyeköy tunnel alignment have been evaluated in terms ofexcavation mechanics. The Istanbul Metro Project between Kabatas-Mecidiyekoy stations includes two types oftunnel excavations, tunnel boring machines (TBM) and New Austrian Tunneling Method (NATM). The total length ofthe two lines of the tunnel to be opened using TBM is 6180 m. In addition, the total length of the two lines to be openedby NATM method is 4490 m. In this study, soil and rock units along the Kabataş-Mecidiyeköy tunnel alignment wereclassified in terms of engineering geology, and tunneling, and the effects of difficult ground conditions on tunnelexcavation were investigated. In addition, the related information is given for the permeability of the geological unitsand the groundwater level.

ABSTRACT: Scientific investigations for surface subsidence caused by groundwater date go back to 1890s. Technologicaland industrial developments have rapidly increased the demand for groundwater and this resulted heavily use ofgroundwater resources. This phenomenon, observed in industrial areas and causing damage to infrastructures,has been related to heavy production of water-oil-and gas. In the following years, research studies have beenfocused on mathematical formulation of the interrelated mechanism of fluid withdrawal and subsidence. In theformulation, mechanical and physical behaviour of the flow and subsidence mechanisms are used together toanalyze their interrelationships. Research studies have been accelerated by Terzaghis consolidation model andBiots mathematical formulation of the phenomenon. In the following years, solution of the equations were tried byanalytical methods, however, they were not applicable to complex problems. Use of the numerical methods (Finite Elements and Finite Differences) and high capacity computers have been applied to solve the problems and this hasspeeded up the research studies.This paper summarizes the research studies related to subsidence due to fluid withdrawal and the scientificdevelopment has been reviewed. The mechanisms of subsidence and fluid flow have been explained and caseexamples are given from countries which seriously suffer from surface subsidence.

ABSTRACT: Nepheline syenite is a siliciously poor syenitic rock composed of nepheline, sodium and alcaline feldspars.Although it is wide spread on the earth, the nepheline deposits that have economic value are limited. Commerciallyspeaking, nepheline syenite contains at least 20% nepheline and 60% feldspar. Such economic deposits are in Russia,Canada, Norway, Brazil, China and Turkey. Main uses of nepheline syenite are glass and ceramic industries. It isa source of alumina (Al2O3) and plays a role of melting products such as sanitary ware, porcelain, tile, glass andfiberglass. Because of the numerous advantages on ceramic and glass products, its consumption is high in Asia,Europe and America. In this review, characteristics of nepheline syenite, its formation, production and consumption,usage areas and technology are given
