Modeling of rainfall-runoff relationship at the semi-arid small catchments using artificial neural networks
(Springer-Verlag Berlin, 2006)The artificial neural networks (ANNs) have been applied to various hydrologic problems in recently. In this paper, the artificial neural network (ANN) model is employed in the application of rainfall-runoff process on a ... -
Mapping field surface soil moisture for hydrological modeling
(Springer, 2007)Soil moisture is a major control variable on hydrological processes both at the storm event scale and in the long term. The aggregate effect on the mean water balance over an area can be quantified successfully using ... -
Web-based quality control of ready mixed concrete
(Pergamon-Elsevier Science LTD, 2007)The ready mixed concrete industry is an important part of today's construction business environment. This industry provides the required quality of concrete used in construction works. The production of this concrete has ... -
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% ... -
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 ... -
Impact of cyclic wetting-drying on swelling behavior of lime-stabilized soil
(Pergamon-Elsevier Science LTD, 2007)In this study, the impact of cyclic wetting and drying on swelling behavior of lime-stabilized clayey soils has been investigated. Swelling potential and swelling pressure tests have been carried out on soil mixtures with ... -
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 ... -
The effects of filler glasses on mechanical properties of concrete
(Trans Tech Publications LTD, 2004)According to the relevant literature, the utilisation of different kind of glasses in concrete introduces positive effect on the mechanical behaviour. The factor affecting physical and mechanical properties and chemical ... -
Mechanical and microstructural properties of heated and polluted kaolinite and bentonite
(Trans Tech Publications LTD, 2004)High temperatures and pollution due to the storage of nuclear wastes in deep soil influence the mechanical properties and microstructure of kaolinite and bentonite. In this study, 0.5 N CaCl2 and 2000 ppm ZnCl2 solutions ... -
Utilization of ceramic wastes in the construction sector
(Trans Tech Publications LTD, 2004)Ceramic wastes causing a serious problem are polluting the environmental problem in Eskisehir Region, Turkey. In this paper, were studied three wastes, ceramic mud wastes (CMW), crushed ceramic tile wastes (CCTW) and ceramic ... -
Optimal polypropylene fiber amount determination by using gyratory compaction, static creep and Marshall stability and flow analyses
(Elsevier Sci LTD, 2013)Utilizing gyratory compaction technique for the preparation of asphalt specimens with 100 mm diameter moulds is an effective and realistic way of pavement laboratory testing. In fact, Marshall compaction is not a suitable ... -
Web-Based Contractor Evaluation System for Mass-Housing Projects in Turkey
(Vilnius Gediminas Tech University, 2012)Determining the most appropriate contractor for a construction project is a highly critical issue. Selecting the right contractor for the right job can significantly influence the overall project performance. In the selection ... -
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 ... -
Ground water contaminant transport by nondivergence-free, unsteady and nonstationary velocity fields
(Elsevier Science BV, 2006)Pore flow velocity is assumed to be a nondivergence-free, unsteady, and non-stationary random function of space and time for ground water contaminant transport in a heterogeneous medium. The laboratory-scale stochastic ... -
The effect of non divergence-free velocity fields on field scale ground water solute transport
(Springer, 2006)Solute plume subjected to field scale hydraulic conductivity heterogeneity shows a large dispersion/macrodispersion, which is the manifestation of existing fields scale heterogeneity on the solute plume. On the other hand, ... -
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 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 ... -
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 ... -
On the using cumulant expansion method and van Kampen's lemma for stochastic differential equations with forcing
(Springer, 2013)Second-order exact ensemble averaged equation for linear stochastic differential equations with multiplicative randomness and random forcing is obtained by using the cumulant expansion ensemble averaging method and by ...
