Device for measuring soil erosion at a level below the surface and measurement method

摘要

The device has a liquid injection unit (7) fixed tightly at an end of a hollow injecting tube (2) and a liquid reservoir (1). An injection hole (8) is located above a head (6), where the hole injects liquid into soil (3). A recuperating unit recuperates the liquid from the soil at interior level of a surface, and has a liquid channeling hole (10) communicated with a chamber (9). A transferring unit has an expulsion hollow tube (12) connecting the chamber and a turbidimeter at the surface, where the tube (12) is independent of the tube (2). An independent claim is also included for a method for measuring soil erosion at a lower level of a surface.
