Kinematic wave theory for transient bed sediment waves in alluvial rivers
(American Society of Civil Engineers, 2008-05)
Transient bed sediment waves in alluvial rivers have been described using a multitude of hydraulic formulations. These formulations are based on some form of the St. Venant equations and conservation of mass of sediment ...
Evaluation and assessment of meteorological drought by different methods in Trarza Region, Mauritania
(Springer, 2017-02)
Drought Indexes (DIs) are commonly used for assessing the effect of drought such as the duration and severity. In this study, long term precipitation records (monthly recorded for 44 years) in three stations (Boutilimit ...
Evaluation of a physically based quasi-linear and a conceptually based nonlinear Muskingum methods
(Elsevier, 2017-03)
Two variants of the Muskingum flood routing method formulated for accounting nonlinearity of the channel routing process are investigated in this study. These variant methods are: (1) The three-parameter conceptual Nonlinear ...
Simulating transient sediment waves in aggraded alluvial channels by double-decomposition method
(American Society of Civil Engineers, 2011-04)
By using the double-decomposition (DD) method, this study simulates transient sediment waves caused by aggradation described by a diffusion-type partial differential equation (PDE). The DD method solves the PDE by decomposing ...
Principle component analysis in conjuction with data driven methods for sediment load prediction
(Springer, 2013-05)
This study investigates sediment load prediction and generalization from laboratory scale to field scale using principle component analysis (PCA) in conjunction with data driven methods of artificial neural networks (ANNs) ...
Trait-based heterogeneous populations plus (TbHP+) genetic algorithm
(Elsevier, 2009-02)
This study developed a variant of genetic algorithm (GA) model called the trait-based heterogeneous populations plus (TbHP+). The developed TbHP+ model employs a memory concept in the form of immunity and instinct to provide ...
GA-optimized model predicts dispersion coefficient in natural channels
(IWA Publishing, 2009)
Models whose parameters were optimized by genetic algorithm (GA) were developed to predict the longitudinal dispersion coefficient in natural channels. Following the existing equations in the literature, ten different ...
Passenger flows estimation of light rail transit (LRT) system in İzmir, Turkey using multiple regression and ann methods
(Faculty of Transport and Traffic Sciences, University of Zagreb, 2012)
Passenger flow estimation of transit systems is essential for new decisions about additional facilities and feeder lines. For increasing the efficiency of an existing transit line, stations which are insufficient for trip ...
Two-dimensional finite elements model for selenium transport in saturated and unsaturated zones
(Springer, 2010-10)
A two-dimensional finite element model was developed to simulate species of selenium transport in two dimensions in both saturated and unsaturated soil zones. The model considers water, selenate, selenite, and selenomethionine ...
Genetic algorithm-based discharge estimation at sites receiving lateral inflows
(American Society of Civil Engineers, 2009)
The genetic algorithm (GA) technique is applied to obtain optimal parameter values of the standard rating curve model (RCM) for predicting, in real time, event-based flow discharge hydrographs at sites receiving significant ...
