Velocity Profile of a Propeller moving through a Channel
In this post, we would like to demonstrate how the propeller transfers the energy to the water column causing sediment resuspension.
Propeller Wash Simulation Using Historical Ship Track Data
Simulation of the impacts of propeller wash in hydrodynamic and sediment transport models requires detailed information on ship travel routes and the physical characteristics of each ship.
The Importance of Propeller Wash Modeling
Many urban waterfronts are contaminated with metals, petroleum hydrocarbons, and other organic chemicals. The contamination could be as much as 20 feet…
Modeling Sediment Resuspension in a Coastal Environment Due to Ship Traffic
Sediment resuspension occurs in harbors across the world as a function of propeller-induced water velocities, and resulting shear stress, at the sediment-water interface. While such events occur with….
EFDC+ with Hydrologic Simulation Program-Fortran (HSPF)
As part of DSI’s committment to the scientific and modeling community, DSI is now providing a template script that modelers can use to run an HSPF model, process the output, run the EFDC+ model, and plot the output.
