Bedload Trap Database

A bedload trap database was developed for gravel bedload data collected between 1998 and 2015 for 14 studies at 12 field sites. The database contains about 1,700 estimates of cross-section averaged transport rates from almost 8,500 individual bedload trap samples. The following publication provides a summary of the how the database was developed:


The table below lists each study site and the year of bedload trap sampling. From the table, a zip file can be downloaded for each bedload trap study and contains the following information:

  • Source data and analyses, which are presented in six Excel spreadsheet files (bedload data, bed-material data, discharge data, seasonal hydrograph data, peak-flow recurrence interval data, topographic site survey data).
  • A folder containing annotated site photos.
  • A site report summarizing the results.
