ABSTRACT:
The present invention is drawn to soil erodibility testing utilizing: an outer backwater tank, which during testing is filled with water; an inner liner positioned at least partially within the outer backwater tank for minimizing return turbulence and providing a mount for either a feed tube or pin profiler means, and; a feed tube having a nozzle thereon, which is positioned within the interior of the inner liner. Water is forced through the feed tube and nozzle, into contact with soil to be tested, so that at least a portion of the soil is removed by erosion. The volume of soil removed by erosion is determined based on the differences between an initial soil profile and an eroded soil profile, which may be measured with a pin profiler means.
