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 ... -
Electricity production opportunities from multipurpose dams (case study)
(Pergamon-Elsevier Science LTD, 2007)The hydropower is the leading source of renewable energy. It provides more than 97% of all electricity generated by renewable sources. The main advantage of hydro systems is elimination of the cost of fuel. Hydropower on ... -
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 ... -
Retained properties of concrete exposed to high temperatures: Size effect
(John Wiley & Sons LTD, 2009)Concrete as a construction material is likely exposed to high temperatures during fire. The retained properties of concrete after such exposures are still of great importance in terms of the serviceability of structures. ... -
Improving daily streamflow forecasts in mountainous Upper Euphrates basin by multi-layer perceptron model with satellite snow products
(Elsevier Science BV, 2016)This paper investigates the contribution of Moderate Resolution Imaging Spectroradiometer (MODIS) satellite Snow Cover Area (SCA) product and in-situ snow depth measurements to Artificial Neural Network model (ANN) based ... -
Basin/Reservoir System Integration for Real Time Reservoir Operation
(Springer, 2016)This paper demonstrates the basin/reservoir system integration as a decision support system for short term operation policy of a multipurpose dam. It is desired to re-evaluate and improve the current operational regulation ... -
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 ... -
Contribution of Built Environment Design Elements to the Sustainability of Urban Renewal Projects: Model Proposal
(Asce-Amer Soc Civil Engineers, 2019)Urban renewal aims to solve the problems caused by unplanned urbanization and urban aging, and it presents a significant opportunity to create sustainable urban areas in Turkey, where a major urban renewal movement was ... -

(Sila Science, 2011)In this paper, the small hydropower potentials of the existing multipurpose dams in the Porsuk River Basin were investigated. For this purpose, the Porsuk River Basin was selected as the research area. The objective of the ... -
Modeling monthly pan evaporations using fuzzy genetic approach
(Elsevier Science BV, 2013)This study investigates the ability of fuzzy genetic (FG) approach in estimation of monthly pan evaporations. Various monthly climatic data, that are, solar radiation, air temperature, relative humidity and wind speed from ... -
Modeling rainfall-runoff process using soft computing techniques
(Pergamon-Elsevier Science LTD, 2013)Rainfall-runoff process was modeled for a small catchment in Turkey, using 4 years (1987-1991) of measurements of independent variables of rainfall and runoff values. The models used in the study were Artificial Neural ... -
Modeling soil temperatures at different depths by using three different neural computing techniques
(Springer Wien, 2015)This study compares the accuracy of three different neural computing techniques, multi-layer perceptron (MLP), radial basis neural networks (RBNN), and generalized regression neural networks (GRNN), in modeling soil ... -
Real-Time Flood Control by Tree-Based Model Predictive Control Including Forecast Uncertainty: A Case Study Reservoir in Turkey
