Abstract

A-priori estimates of maximum scour depth are important for bridge engineers, managers and owners. HEC-18 is an established method which uses empirical equations to estimate bridge scour. This paper applies the HEC-18 methodology to compute maximum scour depth for 936 bridge piers for which field scour depth measurements are available from an online database from the United States Geological Survey (USGS). The results are in general agreement with past research efforts which suggest that the HEC-18 methodology tends to overestimate maximum bridge pier scour depth. The database is also categorized into various sub-sets to study the effect of different particle sizes and devices used to measure scour in the field.
