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.

Diagnosis of adnexal tumors involves a careful physical … In physics, attenuation (in some contexts, extinction) is the gradual loss of flux intensity through a medium. For instance, dark glasses attenuate sunlight, lead attenuates X-rays, and water and air attenuate both light and sound at variable attenuation rates. Hearing protectors help reduce acoustic flux from flowing into the ears. This phenomenon is called acoustic attenuation and is measured in decibels (dBs).
