In this paper we study the large scale transport of the DNA particles through a heterogeneous micro array in the framework of homogenization theory. We derive the macro scale particle transport equation and show that for transport of particles in a diverge ...
We investigate the entrainment, deposition, and motion of coarse spherical particles within a turbulent shallow water stream down a steep slope. This is an idealization of bed-load transport in mountain streams. Earlier investigations have described this k ...
Streambank erosion is an aspect of flood hazards that has been largely neglected to date due to its complexity. The INTERREG IIIb NWE project « Strategies and Actions for Flood Risk Management » (SAFER) has recognized its importance by including this aspec ...
The problem of transport of suspended sediment after the break of a dam on an inclined bed is considered. To that end we use the shallow-water approximation for arbitrary, constant slopes of the bottom, taking into consideration the effect of friction. The ...
We investigate the entrainment, deposition and motion of coarse spherical particles within a turbulent shallow water stream down a steep slope. This is an idealization of bed-load transport in mountain streams. Earlier investigations have described this ki ...
A two-dimensional numerical model was presented for the simulation of sediment transport under oscillatory sheet flow conditions in the nearshre zone. Most existing mathematical models for predicting sediment transport in this area are based on the governi ...
A critical review of conceptual and mathematical models developed in recent decades on sediment transport in the swash zone is presented. Numerous studies of the hydrodynamics and sediment transport in the swash zone in recent years have pointed out the im ...
Increased sediment production resulting from the erosion of unprotected soil in a catchment may result in severe changes in the morphodynamics and hydrodynamics of mountain rivers. Sediment overfeeding can lead to the degradation of salmonids' spawning sit ...
In alpine regions of Europe, river training works were typically the reason for the transformation of wide and braided rivers into linear river systems with a lack of structural diversity, i.e. gravel banks, islands, woody debris, riffles or pools. These i ...
This numerical investigation was carried out to advance mechanistic understanding of sediment transport under sheet flow conditions. An Euler-Euler coupled two-phase flow model was developed to simulate fluid-sediment oscillatory sheet flow. Since the conc ...
