Onsager’s reciprocal relations in electrolyte solutions: I. Sedimentation and electroacoustics

In the framework of irreversible thermodynamics, we show that the sedimentation current in electrolyte solutions is mathematically equivalent to the low frequency limit of the ionic vibration current, appearing in the presence of an acoustic wave. This non-trivial result is obtained thanks to a careful choice of the reference frame used to...

Onsager’s reciprocal relations for electroacoustic and sedimentation: Application to (concentrated) colloidal suspensions

In this article, the relations for electroacoustic phenomena, such as sedimentation potential, sedimentation intensity, colloid vibration potential, colloid vibration intensity/current, or electric sonic amplitude, are given, on the basis of irreversible thermodynamics. This formalism allows in particular to discuss the different expressions for...

The Impact of Soil Erosion in the Upper Blue Nile on Downstream Reservoir Sedimentation

Population growth in the Blue Nile Basin has led to fast land-use changes from forest to agricultural land, which resulted in speeding up the soil erosion processes producing highly negative impacts on the local soil fertility and agricultural productivity. The eroded sediment is transported downstream by water and sinks in the lower basin where...

The behaviour of fines released due to dredging: A literature review

In 2001a DIOC-projectwas started at Delft University of Technologyon the dispersion of fines during sand mining. In this project the behaviour and spreading of fines, which are released through the overflow of a dredging ship, is studied. Laboratory and field studies will be carried out to determine the behaviour and spreading of the fines....

A new morphological schematization of the Western Scheldt estuary, The Netherlands

The present paper describes an analysis of the morphological integrityof the multiple channel system (MCS) of the Western Scheldt estuary. The tidal flats and surrounding ebb and flood channels form morphological cells, and the entire MCS can be schematized as a chain of such cells. The major ebb and flood channels have lost their one time...
