mud stream

The foul-smelling mud stream went halfway up the trunks of his peach and pear trees and filled his wells and irrigation channels.

I got no farther than the parking lot before realizing that those ruts in the road would be mud streams and even in a 4x4, my odds weren't especially good.

Similar phenomena include mudflow, mud stream, debris flow (e.g. in high mountains), jökulhlaup, and lahar (from volcanoes, see also pyroclastic flow).

Fractured zones such as those encountered around the Buchan field can lead to a complete or serious loss of the entire mud stream as it is absorbed by the formation.

Roughly twenty-five percent of the unflooded areas were buried under lava and volcanic ash, old lahars or mud streams, pumice, and what Yaleu's geologists called pyroclastic fragments, such as scoriae bombs.

Mud logging technicians in an oil field drilling operation determine positions of hydrocarbons with respect to depth, identify downhole lithology, monitor natural gas entering the drilling mud stream, and draw well logs for use by oil company geologist.
