Sediment Transport Analysis of Sesayap River, Malinau District, North Kalimantan
River could have a very important role in improving the economy of a country when it is correctly and properly utilized. Nevertheless, rivers in Indonesia also have various problems, i.e.

The grain size gap and abrupt gravel-sand transitions in rivers due to suspension fallout [PDF]
Median grain sizes on riverbeds range from boulders in uplands to silt in lowlands; however, rivers with ~1–5 mm diameter bed sediment are rare. This grain size gap also marks an abrupt transition between gravel- and sand-bedded reaches that is unlike ...

Modelling pick-up and deposition in a dune model [PDF]
Water level forecasts with a high river water discharge depend on accurate predictions of the evolution of river dunes. For flood earlywarning systems complexity in sub models is a drawback as it leads to (too) large computation times.

Modeling bed evolution using weakly coupled phase-resolving wave model and wave-averaged sediment transport model [PDF]
In this paper, we propose a model for the simulation of the bed evolution dynamics in coastal regions characterized by articulated morphologies.

Determining the scales of collective entrainment in collision-driven bed load [PDF]
Fluvial bed-load transport is notoriously unpredictable, especially near the threshold of motion where stochastic fluctuations in sediment flux are large.

Bed shear stress measurements over rough fixed and mobile sediment beds in swash flows [PDF]
Direct measurements of bed shear stress have been conducted over rough fixed and mobile sediment beds in dambreak driven swash flows. The comparison between rough fixed and mobile bed results indicated the significant importance of grain borne shear ...

Coupling of Boussinesq and sediment transport model in a wave flume [PDF]
Boussinesq type equation has been coupled with sediment transport model to simulate sediment\ud transport in a wave flume. A new eddy viscosity model has been applied to calculate wave decay as well\ud as suspended sediment concentration.

A COMPARATIVE STUDY OF SOME OF THE SEDIMENT TRANSPORT EQUATIONS FOR AN ALLUVIAL CHANNEL WITH DUNES [PDF]
The present work is a comparative evaluation of some of the well known sediment transport equations for the condition of dunes on the bed. It is fairly clear that no single equation provides reliable estimates of the total load of sediment transported ...

The Effect of Hydraulic Partitioning on Prediction the Rate of Bed Load Transport in Gravel-bed Rivers using Support Vector Machine [PDF]
Evaluation and prediction of sediment transport and associated processes have been one of the main issues of hydraulic and river engineers. There are some variables which affect the amount of bed load of a stream or river which may carry such as ...

Sediment Bed-Load Transport: A Standardized Notation
Morphodynamic processes on Earth are a result of sediment displacements by the flow of water or the action of wind. An essential part of sediment transport takes place with permanent or intermittent contact with the bed.
