Abutment Scour Amplification Factor Calculator

The Amplification Factor is used in the NCHRP 24-20 method to compute abutment scour. It serves the same function as the Kv and Kf parameters do in the ABSCOUR 10 method. The amplification factor is automatically computed by ABSCOUR 10 for the NCHRP 24-20 method. This utility can be used to verify the ABSCOUR 10 computations for the amplification factor for the NCHRP 24-20 method. The background on the use of the Abutment Scour Amplification Factor is discussed in FHWA Manual HEC-18, Fifth Edition, Section 8.6.3.
