Flow attenuation definition
WebFeb 25, 2024 · The attenuation coefficient is a measure of how easily a material can be penetrated by an incident energy beam (e.g. ultrasound or x-rays ). It quantifies how much the beam is weakened by the material it is passing through. In X-rays, there are two types of attenuations 2: linear attenuation coefficient (µ) mass attenuation coefficient (μ/ρ) WebJun 11, 2024 · In these cases, streamflow will remain elevated for a longer period of time. This phenomenon, known as peak attenuation, can be attributed to several variables. A …

WebAttenuation is a general term that refers to any reduction in the strength of a signal . Attenuation occurs with any type of signal, whether digital or analog . Sometimes called loss , attenuation is a natural consequence of signal transmission over long distances. The extent of attenuation is usually expressed in units called decibels (dBs). WebFor orthophosphate, minimum relative attenuation was observed at about 0.1 milligram of phosphorus per liter (mg P/L) for both low- and high-flow conditions. Generally, the temporal dynamics of nutrient attenuation are dependent on the travel time through a given reach, the proportion of flow in contact with the sediment, and the amount of ...

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.
WebFlow attenuation means prolonging the flow time of runoff to reduce the peak discharge. " Hydrology model ” may include one of the following : Sample 1 Sample 2 WebAttenuation. Reduction of power, e.g., due to passage through a medium or electrical component. Attenuation in electrical systems is commonly expressed in dB. Attenuator. Device which reduces a signal by a specific amount, commonly given in dB. Axial plane. See Transverse plane or transaxial plane. Autotuning.
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).
