Product Description

Erosion Function Apparatus

Erosion function apparatus (EFA) was designed and built to prevent bridge failures by measuring the erodibility of soil. 
These advantages include: minimum sample disturbance; measurement of erosion rate vs. shear stress; measurement of critical shear stress, and incorporation of the test results from the SRICOS scour prediction method.
Used in conjunction with the SRICOS scour prediction method, it can provide more accurate erodibility measurements and scour predictions than previously obtainable. 
Applications for its use include  scour at bridges, piping of dams, beach erosion and surface erosion problems. 
In the case of scour at bridges, the EFA leads to improved accuracy on scour depth predictions, offering several advantages over previous test methods. 
Erosion function apparatus uses standard 3.0" OD x 2.875: ID (76.2 x 73 mm) Shelby tubes. 
The SRICOS method improves the accuracy of pier scour predictions.

The EFA uses either of two variants of the SRICOS method :

The Simple SRICOS Method
1) Calculate the maximum depth of scour.
2) Collect soil samples at the site.
3) Test samples in the EFA to obtain the erosion rate vs. hydraulic shear stress applied.
4) Calculate the equivalent time for a given design life of the bridge and for the design velocity.
5) Using known equations, calculate the scour
depth at the end of the design life.

Features :-

Records and tabulates test data.
7" touch screen interface
