چکیده
The paper presents recommendations for using the results obtained in sediment transport simulation and modeling of channel deformations rivers. This work relates to issues empirical water flow characteristics natural riverbeds with a movable bottom (alluvial channels) which are extremely complex. study shows that calculation rivers, it is expedient use dependences Chézy’s coefficient assessing roughness mixture, or form based on field investigation data. Three models most commonly used original formulas Meyer-Peter Müller (1948), Einstein (1950) van Rijn (1984). deals hydraulic resistance improving river model riverbed transformation basis previous research verify 296 measurements Central-East European lowland performed test calculations show modified formula gives best from all considered variants.

Sediment Transport in Unsteady Flow Conditions
Sediment transport under unsteady flow condition is studied experimentally. In the first step, sediment transport under different steady flow conditions was measured and an empirical equation was derived for its calculation. In the next step, two continuous and three stepwise hydrographs were generated in the flume, and their sediment transport rate was measured. The continuous hydrographs were...
متن کاملEstimation of Sediment Transport Rate of Karun River (Iran)
Several types of sediment transport equations have been developed for estimation of the river sediment materials during the past decades. The estimated sediment from these equations is very different, especially when they applied for a specific river. Therefore, choice of an equation for estimation of the river sediment load is not an easy task. In this study 10 important sediment transport equ...
متن کاملTransport Property Estimation of Non-Uniform Porous Media
In this work a glass micromodel which its grains and pores are non-uniform in size, shape and distribution is considered as porous medium. A two-dimensional random network model of micromodel with non-uniform pores has been constructed. The non-uniformity of porous model is achieved by assigning parametric distribution functions to pores throat and pores length, which was measured using ima...
متن کاملThe Effect of Convergence and Divergence on Flow Pattern and Sediment Transport in Lateral Intakes
Water supply at a desired rate at any time to meet the water requirements regardless of river discharge must be considered in the general design of intakes provided that the needs do not exceed the river flow. Due to the lack of necessary information in this field and the importance of sediment transport to the lateral intakes at river bends, this study aimed at understanding the mechanism of t...
متن کاملA Comparative Study of Extreme Learning Machines and Support Vector Machines in Prediction of Sediment Transport in Open Channels
The limiting velocity in open channels to prevent long-term sedimentation is predicted in this paper using a powerful soft computing technique known as Extreme Learning Machines (ELM). The ELM is a single Layer Feed-forward Neural Network (SLFNN) with a high level of training speed. The dimensionless parameter of limiting velocity which is known as the densimetric Froude number (Fr) is predicte...
