Use of petroleum-contaminated drilling wastes as sub-base material for road construction
(Munksgaard Int Publ LTD, 2000)In this study, petroleum-contaminated drilling wastes were stabilized by mixing pozzolanic fly ash, lime and cement with them so they could be used as sub base materials for road construction. This stabilization produced ... -
The mathematical modelling of total nitrogen contamination transport via groundwater from a sugar factory in Eskisehir, Turkey
(Inderscience Enterprises LTD, 2003)In this study, mathematical modelling of the total nitrogen contamination transport in a porous medium was evaluated in order to determine the potential groundwater pollution caused by a sugar factory in the Eski(.)ehir ... -
The use of waste materials in asphalt concrete mixtures
(I W M Business Services LTD, 2003)The purpose of this study was to investigate (a) the effects of rubber and plastic concentrations and rubber particle sizes on properties of asphalt cement, (b) on properties of asphalt concrete specimens and (c) the effects ... -
Use of natural zeolites as a landfill liner
(I W M Business Services LTD, 2003)The purpose of this study is to investigate certain features of a novel material proposed to serve as an impervious liner in landfills. Various ratios of bentonites and zeolites (B/Z) compacted at optimum water content ... -
The lower employment of women in Turkish construction sector
(Pergamon-Elsevier Science LTD, 2004)More than half of the population of Turkey is women. However, although there is an increase in the number of population, they have still been under-represented in the labour force. The conceptual and empirical elements ... -
Energy from renewable sources inTurkey: Status and future direction
(Taylor & Francis Inc, 2004)Turkey is an energy importing country. Turkey's indigenous energy sources are limited and the country is heavily dependent on the import of primary energy from abroad. More than half of the energy requirement has been ... -
Electricity from thermal and hydropower sources in Turkey: Status and future direction
(Taylor & Francis Inc, 2004)In 1995, electricity production reached 862 TWh, while in 1971 it was only 8.6 TWh. Electricity production is expected to reach 304 TWh by 2010. The sharp growth of the energy sector has been accompanied by institutional ... -
Thomas-Fiering Modeli İle Sentetik Akış Serilerinin Hesaplanmasında Yeni Bir Yaklaşım
(2004)Baraj hazne hacmi, akarsu aylık su akımları ile aylık su ihtiyaçlarının uzunca bir periyot süresince karşılaştırılması sonucu tespit edilir. Akarsuya ait aylık su akımlarının tahmin edilmesi için eldeki mevcut olan değerlerden ... -
Determination of soil hydraulic properties using pedotransfer functions in a semi-arid basin, Turkey
(Copernicus Gesellschaft Mbh, 2004)Spatial and temporal variations in soil hydraulic properties such as soil moisture 0(h) and hydraulic conductivity K(theta) or K(h), may affect the performance of hydrological models. Moreover. the cost of determining soil ... -
Sustainable development of small hydropower plants (SHPs)
(Taylor & Francis Inc, 2004)The aim of this article is to investigate the small hydropower plants (SHPs) in Turkey. Total hydropower potential of Turkey is annually 433,000 GWh. Almost 50% of the total potential is technically exploitable and 29% ... -
Turkey's water resources and hydropower potential
(Sage Publications Inc, 2005)The aim of this paper is to investigate water resources in Turkey. Annual rainfall varies from 220 torn to 2500 mm with an average of 643 mm, which means total volume of 501 km(3) and average annual potential of surface ... -
Using MODIS snow cover maps in modeling snowmelt runoff process in the eastern part of Turkey
(Elsevier Science Inc, 2005)Water perhaps is the most valuable natural asset in the Middle East as it was a historical key for settlement and survival in Mesopotamia, "the land between two rivers". At present, the Euphrates and Tigris are the two ... -
Modelling the temporal variation in snow-covered area derived from satellite images for simulating/forecasting of snowmelt runoff in Turkey
(Taylor & Francis LTD, 2005)Monitoring the change of snow-covered area (SCA) in a basin is vitally important for optimum operation of water resources, where the main contribution comes from snowmelt. A methodology for obtaining the depletion pattern ... -
An extended pressure application for transient seepage problems with a free surface
(Begell House Inc, 2005)In this paper, a new finite-difference-solution technique for solving transient seepage problems with an unknown free sur ace has been proposed. The governing finite-difference equations were derived using flux conservation ... -
Turkey's non-fossil energy sources and positive expectations in the next decades
(Taylor & Francis Inc, 2005)According to some projections, Turkey's primary energy demand is expected to increase four times its 1998 value in the next 20 years. Turkish gas demand is expected to increase more than five folds in 2010 and eight times ... -
Electricity generation from existing multipurpose dams in Turkey
(Multi Science Publ Co LTD, 2005)The aim of this article is to investigate the hydropower potential of multipurpose dams constructed with the purpose of supplying irrigation, domestic water supply, flood control, navigation, recreation, sanitation, and ... -
Transport modelling of copper contamination in groundwater caused by a wood preservation plant
(Iwa Publishing, 2005)Contaminants can adhere to soil and subsequent rainfall can leach the adhered contaminant into groundwater. Transport models can determine the main features of contaminant and carrier transport in groundwater systems, and ... -
The use of kaolinite/zeolite mixtures for landfill liners
(Inderscience Enterprises LTD, 2005)The use of kaolinite/zeolite mixtures as alternative landfill materials has been studied. The ratios of kaolinite/zeolite used were K/Z = 0.1, K/Z = 0.2 and K/Z = 0.3. To determine the geotechnical and physicochemical ... -
A comparative study on the interpretation of concrete core strength results
(Thomas Telford Publishing, 2006)Cores measuring 94 mm and 144 mm in diameter and having length-to-diameter ratios of 2-0, 1.0 and 0.75 were removed from beam specimens produced from different concrete mixtures. Standard cubes and cylinders were also ... -
