“…The PSDb-2014 includes 118 measurements from Montana, with 103 measurements from Holnbeck (2011) and 15 from the NBSD (table 7). [Note: The NBSD includes 41 measurements from Montana; however, 26 were excluded based on guidance from S.R.…”

“…All 118 measurements were included in the PSDb-2014. The Montana data from Holnbeck (2011) represent the single largest coarse-bed pier-scour database collected to date by the USGS, and these high-quality data need no qualifications. In contrast, the Montana data associated with the NBSD may reflect remnant scour holes (S.R.…”

“…Holnbeck, USGS Wyoming-Montana Water Science Center, written commun., January 2014) which should be taken into consideration when using these data in any analysis. Additional information about the Montana data can be found in Holnbeck (2011) and the NBSD (U.S. Geological Survey, 2001) and accessed online (table 4).…”

“…Such data could be misleading for certain data analysis, and it may be of value to identify these data. Screening the PSDb-2014 for such data was beyond the scope of this investigation; however, Gao and others (1993) and Holnbeck (2011) provide guidance for identifying these types of measurements.…”

“…While limitations are associated with the field data in the PSDb-2014, the strengths of this database include (1) the large number of measurements (1,858), (2) the diversity of site characteristics (table 3), and (3) inclusion of the most thoroughly documented and screened field data currently (2014) available (USGS, 2001;Holnbeck, 2011;Sheppard and others, 2011). These field data, in conjunction with the 569 laboratory measurements, offer a valuable resource to researchers and practitioners that can be used in various ways including, but not limited to, (1) evaluating the range of the dimensionless parameters used in the laboratory with the range of those determined in the field, (2) confirming and extending the relations observed in the laboratory data, (3) evaluating the influence of selected variables on pier-scour depth, (4) providing an assessment of the performance of selected scour-prediction equations, (5) identifying ways to improve the performance of selected scour-prediction equations, (6) developing new scourprediction methods through various analysis, (7) defining upper-bound envelopes of pier-scour depth that can provide guidance to practitioners, and (8) making site comparisons using selected field data from the database that have similar characteristics to a site of interest to gain insights into scour potential.…”

AcknowledgmentsThe 2014 USGS Pier-Scour Database (PSDb-2014) includes 2,427 laboratory and field measurements of pier scour. These data represent an extensive investment of time and effort by many investigators to collect, document, and analyze those data. These investigators have made individual and collective contributions to the advancement of the current understanding of pier scour, and the authors of this report acknowledge the investigators' contributions. AbstractThe U.S. Geological Survey conducted a literature review to identify potential sources of published pier-scour data, and selected data were compiled into a digital spreadsheet called the 2014 USGS Pier-Scour Database (PSDb-2014) consisting of 569 laboratory and 1,858 field measurements. These data encompass a wide range of laboratory and field conditions and represent field data from 23 States within the United States and from 6 other countries. The digital spreadsheet is available on the Internet (http://pubs.usgs.gov/ds/845) and offers a valuable resource to engineers and researchers seeking to understand pier-scour relations in the laboratory and field.
