Energy-Based Method for Providing Soil Surface Erodibility Rankings

Measure Soil Erodibility in Situ

The assessment of the erodibility of soil materials is essential for analyzing and modeling rill, gully, streambed, streambank, spillway, and embankment erosion. A submerged jet−testing apparatus has been developed and used for characterizing soil erodibility in several applications as cited in the literature. The apparatus has been developed based on knowledge of the hydraulic characteristics ...

The Effect of Volcanic Ash Incorporation, Slope and Vegetation on Soil Surface Runoff and Erodibility Characteristics

Regional Study of No-Till Impacts on Near-Surface Aggregate Properties that Influence Soil Erodibility

Evaluation of Soil Erosion and Soil Erodibility Factors for Composted Organics on Highway Right-of-Ways

Runoff and interrill erosion were measured on three composted organics applied at 5-cm and 10-cm depths, a topsoil treatment (15-cm application), and the existing soil on a highway embankment with a 3 to 1 slope. Treatments were tested immediately after preparation and six weeks later to allow for the vegetative cover crop to grow. Rainfall simulations were conducted at an average intensity of ...

Lessons Learned Using Laboratory Jet Method to Measure Soil Erodibility of Compacted Soils

Overtopping, internal erosion, and piping are the main causes of accidents and failures of embankments for dams, lagoons, and levees. A key parameter in the failure of these structures is the erodibility of the soil materials used in construction of the embankments. The soil materials are typically constructed based on compaction specifications. The jet erosion test (JET) has been developed to ...
