Investigating cohesive sediment dynamics in open waters via grain-resolved simulations

LTFATE Cohesive Sediment Transport Model

hydrodynamics and sediment transport model used to determine the longand short-term stability of dredged material mounds. This technical note (TN) introduces a new cohesive sediment transport submodel for LTFATE, which includes a combined current-wave shear stress calculation and a layered sediment bed model. LTFATE can be accessed via the Internet at the following address: http://www.wes.army....

Sediment Pore Waters

one-dimensional numerical model of cohesive sediment transport in open channel flow

cohesive sediment transport remains a complicated subject that hydraulic engineers are frequently faced with in water-related engineering problems. this is primarily affected by the macroscopic aspects of water-sediment system characteristics. in this paper a 1-d mathematical model was developed to be employed in predicting the cohesive sediment transport under simultaneous conditions of erosio...

Stochastic Flocculation Model for Cohesive Sediment Suspended in Water

Existing flocculation models for cohesive sediments are classified into two groups: population balance equation models (PBE) and floc growth models. An FGM ensures mass conservation in a closed system. However, an FGM determines only the average size of flocs, whereas a PBE has the capability to calculate a size distribution of flocs. A new stochastic approach to model the flocculation process ...
