Models for cohesive sediments describing the evolution of the characteristics of particles

چکیده
Abstract The goal of this paper is to set up a framework designed to take into account the characteristics of sediment particles when transported by water. Our protocol consists in describing the characteristics of sediment particles via an additional variable, and to build operators involving this new variable, modeling the evolution of the particle characteristics. Several such operators are proposed, some based on principles of relaxation toward an equilibrium, and others on a description of the particles’ aggregation and fragmentation process. A discrete version of the latter is also offered for numerical settings.

Cohesive sediments have large specific surfaces which enable them to absorb other cohesive sediments and polar particles such as mud and sodium. Floccules form by joining these particles. The behavior of cohesive sediments in aquatic environments is completely different from that of granular sediments. Under certain value of shear stress, the structure formed from cohesive sediments is divided ...
متن کاملPrediction of Cohesive Sediment Erosion Rate and Analyzing the Effective Parameters Using Artificial Neural Network
Transferring mechanic of cohesive sediments are different from non-cohesive sediments. For determining the erosion rate of non-cohesive sediments, physical parameters such as average diameter and density are used, such as average diameter and density. Due to the nature of the cohesive sediments, their erosion rates are determined interrelated with the shear stress of the bed with fixed coeffici...

In this article, low velocity impact behavior of fiber metal laminate (FML) composite plates is investigated under three different impact energies (12.7 J, 16.3 J and 24.2 J). Here, three modeling techniques are used. In one of the models the inter-laminar damage is neglected (model without delamination) and in other two models this damage is simulated using cohesive element and cohesive surfac...
متن کاملInvestigating abundance and characteristics of microplastics as emerging pollutants in sediments of Taleqan dam and upstream river in Alborz province
Background and Objective: Microplastics (MPs) pollution are considered as a major growing global environmental problem in the past few decades. Dams could be an important reservoir for microplastics accumulation, therefore, in this study the presence of microplastics in sediments of Taleqan Dam and its upstream river was investigated in order to: 1) determine the local status of microplastic po...

Sedimentation and consolidation of cohesive sediments near the dam body can cause many problems such as clogging the bottom outlets and entering the sediments into the hydropower intakes. Flushing of these sediments through the bottom outlet will be successful only if the hydraulic conditions are designed according to the physical and mechanical properties of consolidated sediments. During the ...
