The EFA, Erosion Function Apparatus: An overview Conference Paper uri icon


  • A new apparatus is described to measure the erosion function of a soil. The patented apparatus is called the EFA or Erosion Function Apparatus. The erosion function is the relationship between the hydraulic shear stress applied at the soil-water interface by the water flowing over the soil and the erosion rate of the soil. This erosion function can then be used to predict scour of soil by water.
