Bed shear stress estimation for gravity currents performed in laboratory

  title={Bed shear stress estimation for gravity currents performed in laboratory},
  author={Jessica Zordan and Anton J. Schleiss and M{\'a}rio J. Franca},
Gravity currents are caused by density differences between two fluids which may be due to temperature, dissolved substances or the presence of particles in suspension. In this study saline currents, in which the higher density is produced by dissolved salt, are reproduced in laboratory with the aim to characterize the bed shear stress. Saline currents can in fact be responsible for high erosion rates and the bed shear stress is a quantification of this erosive capacity. The dynamics of buoyancy… CONTINUE READING
