Interpretive Summary: No new research results are reported; interpretive summary not required. NOTE: ASTM does not provide for identification of authorship; however, ASTM requested that Dr. Hanson write this standard to be used in conjunction with use the the jet index testing device that he developed and patented.

Technical Abstract: Erosion resistance of a soil is of concern in vegetated channels, road embankments, dams, levees, spillways, construction sites, etc. This standard has been written to address the estimation of erodibility of a soil by the jet index method. The test method involves either preparing a field site or obtaining a relatively undisturbed soil sample and the subsequent activities for the determination of the erodibility of the soil The apparatus includes a vertical submerged jet, pin profiler, and additional supporting equipment. The jet index is a function of the water velocity from the jet and the amount of scour over time. The jet index method is intended to provide a standard method of expressing erosion resistance for soils.
