Exponential clogging time for a one dimensional DLA

, 2007
When considering DLA on a cylinder it is natural to ask how many particles it takes to clog the cylinder, e.g. modeling clogging of arteries. In this note we formulate a very simple DLA clogging model and establish an exponential lower bound on the ...

Methodology to Evaluate Dripper Sensitivity to Clogging due to Solid Particles: An Assessment

The Scientific World Journal, 2018
Emitter clogging is a major problem in microirrigation systems, which may result from the isolated or combined effects of physical, chemical, and biological agents. Clogging caused by suspended solid particles is the most common plugging form of emitters.

Faunal response to benthic and hyporheic sedimentation varies with direction of vertical hydrological exchange [PDF]

, 2014
1. Sedimentation and clogging of benthic and hyporheic zone substrates is increasingly being recognised as one of the greatest threats to the ecological integrity of riverine ecosystems globally. This ex-situ study examined the influence of sedimentation
