Kinematic wave model of bed profiles in alluvial channels
(American Geophysical Union, 2006-06-21)
A mathematical model, based on the kinematic wave (KW) theory, is developed for describing the evolution and movement of bed profiles in alluvial channels. The model employs a functional relation between sediment transport ...
Kinematic wave model for transient bed profiles in alluvial channels under nonequilibrium conditions
(American Geophysical Union, 2007-12-27)
Transient bed profiles in alluvial channels are generally modeled using diffusion (or dynamic) waves and assuming equilibrium between detachment and deposition rates. Equilibrium sediment transport can be considerably ...
Predicting Longitudinal Dispersion Coefficient in Natural Streams by Artificial Neural Network
(2005-11-01)
An artificial neural network (ANN) model was developed to predict the longitudinal dispersion coefficient in natural streams and rivers. The hydraulic variables [flow discharge (Q), flow depth (H), flow velocity (U), shear ...
Case Study: Finite Element Method and Artificial Neural Network Models for Flow through Jeziorsko Earthfill Dam in Poland
(2005-06-01)
A finite element method (FEM) and an artificial neural network (ANN) model were developed to simulate flow through
Jeziorsko earthfill dam in Poland. The developed FEM is capable of simulating two-dimensional unsteady and ...
ANN and Fuzzy Logic Models for Simulating Event-Based Rainfall-Runoff
(2006-12-01)
This study presents the development of artificial neural network _ANN_ and fuzzy logic _FL_ models for predicting event-based rainfall runoff and tests these models against the kinematic wave approximation _KWA_. A three-layer ...
