DEVICE FOR MEASURING SOIL EROSION AT A LEVEL BELOW THE SURFACE AND MEASURING METHOD.

摘要

A device for measuring soil erosion at a level below the surface has a head (6) at one end of a first hollow tube (2), the first hollow tube (2) having at least one injection (8) of liquid located above the head (6), means for recovering the injected liquid having a collection hole (10) of the liquid, communicating with a chamber (9), and secondly transfer means, to a turbidimeter (14) provided on the surface, of the liquid recovered in the chamber, the transfer means comprising a second hollow tube (12) expulsion axis substantially parallel to the first hollow tube (2). The invention also relates to a method of implementing the device.
