Calibration and verification of QUAL2E using Genetic algorithm optimization
GÖKTAŞ, Recep Kaya; Aksoy, Ayşegül (American Society of Civil Engineers (ASCE), 2007-03-01)
In this study, the QUAL2E model is linked with a genetic algorithm (GA) in order to conduct the calibration and verification of the model. The efficacy of the optimization model was tested for different observation data quality represented by the perfect and noisy data assumptions. Four cases were studied. In the first (base) case, calibration was conducted for the reach-variable reaeration coefficient (K2) and the sediment oxygen demand rate (K4). In the second case, the number of sampling points was incre...
Calibration and Evaluation of WRF-Hydro Modeling System for Extreme Runoff Simulations: Use of High-Resolution Sea Surface Temperature (SST) Data
Kılıçarslan, Berina Mina; Yücel, İsmail; Department of Civil Engineering (2022-2)
This study investigates the impact of the spatio-temporal accuracy of four different sea surface temperature (SST) datasets on the accuracy of the Weather Research and Forecasting (WRF)-Hydro system to simulate hydrological response during two catastrophic flood events over the Eastern Black Sea (EBS) and the Mediterranean (MED) regions of Turkey. Three daily-updated and high spatial resolution external SST products (GHRSST, Medspiration, and NCEP-SST) and one coarse-resolution and time-invariant SST produc...
Calibration and evaluation of the 3rd generation wave models under extreme conditions in black sea basin
Kirezci, Çağıl; Özyurt Tarakcıoğlu, Gülizar; Department of Civil Engineering (2016)
In this study, performances of 3rd generation wave models, SWAN and WAVEWATCH III, under storm conditions in Black Sea are compared considering two different wind source (CFSR and ECMWF operational) data. Basic wave parameters (outputs of the spectral wave models) demonstrate that the governing physical processes in deep water consist of three terms; wind-wave interaction, dissipation of energy due to whitecapping and swell, and nonlinear wave-wave interactions. Effects of different methodologies for the so...
Calibration of the CMS drift tube chambers and measurement of the drift velocity with cosmic rays
Chatrchyan, S.; et. al. (IOP Publishing, 2010-03-01)
This paper describes the calibration procedure for the drift tubes of the CMS barrel muon system and reports the main results obtained with data collected during a high statistics cosmic ray data-taking period. The main goal of the calibration is to determine, for each drift cell, the minimum time delay for signals relative to the trigger, accounting for the drift velocity within the cell. The accuracy of the calibration procedure is influenced by the random arrival time of the cosmic muons relative to the ...
Calibration of the finite element model of a long span cantilever through truss bridge using artificial neural networks
Yücel, Ömer Burak; Hasançebi, Oğuzhan; Department of Civil Engineering (2008)
In recent years, Artificial Neural Networks (ANN) have become widely popular tools in various disciplines of engineering, including civil engineering. In this thesis, Multi-layer perceptron with back-propagation type of network is utilized in calibration of the finite element model of a long span cantilever through truss called Commodore Barry Bridge (CBB). The essence of calibration lies in the phenomena of comparing and correlating the structural response of an analytical model with experimental results a...
