Using Historical Data to Examine the Accuracy of Sand Transport Field Measurements in Two Nearshore Marine Settings
A re-Analysis of historical data from two field campaigns was undertaken to examine the accuracy of measurements of bed load (Qb) and total transport (Qtot) of sand in (1) a wave-dominant shoreface off western Newfoundland, Canada, and (2) a tide-dominant inlet of Venice Lagoon, Italy.
