Crab Lab 
Though crabs are disappearing along America’s coasts, research in land-locked Tennessee could help. Students in Biosystems Engineering have designed a project to replenish crab populations.

(1 mention)

Obed Watershed 
For every flowing river in Tennessee, there are many streams that feed it. A group of volunteers on Tennessee’s Cumberland Plateau work to preserve water quality in these tributaries.

(1 mention)

River Cleanup 
Agriculture students worked to clean up the Tennessee River and some of its tributaries of plant growth and trash.

(1 mention)

Little River Facility 
It’s long been an issue in farming – how can we be productive in agriculture and still protect the environment? UT Ag-Research has a new facility dedicated to that cause.

(1 mention)

Water Quality 
Floods, droughts and very hot or cold temperatures - all weather patterns that we experience often in Tennessee. What impact do these weather situations have?

(1 mention)

No-Till Hills 
There was a time when sloped land was just about useless because of frequent soil erosion. But now, hilly terrain can be productive. 'No-till” farming makes it possible.

UT engineers create technology to map rivers 
A UT AgResearch professor has developed an underwater video system that, in combination with surface videos, gives a complete picture of the stream.
