On field studies of suspended matter that forms in a ship canal under the effect of moving ships

Abstract

The results of studies of particulate matter in a navigable channel are given. For the first time, field data on suspension concentration were collected immediately after the passage of ships with different drafts. The concentration of suspended matter is shown to depend on the draft of the passing ship and the type of soils on the bed of the canal. Data are given to characterize the actual settling velocities immediately after the passage of ships. These data, along with the described techniques for direct calculations can be used to assess the anthropogenic impact on the environmental conditions in navigable canals, rivers, and reservoirs.
