WebFlow attenuation is responsible for losing of tie channels and lateral detachment of river and wetland. Related to Flow attenuation Natural attenuation means the reduction in the con- centration and mass of a substance, and the products into which the substance breaks down, due to naturally occurring physical, chemical and biological processes. WebA theoretical investigation has been made of the attenuation and lag of an oscillatory pressure variation applied to one end of a tube, when the other end is connected to a pressure-sensitive element. An elementary theory based on incompressible viscous-fluid flow is first developed.
