In this post, we would like to demonstrate how the propeller transfers the energy to the water column causing sediment resuspension.
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.
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 great frequency and are generally not remarkable, the potential effects of propwash on the erosion, transport, and re-deposition of contaminated sediments can be significant.
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.
With so many new computer languages available today, a question often asked is, “Why is EFDC+ coded in Fortran language?”
EFDC+ support input of spatially and temporally varying boundary conditions as field files, which means user can assign…
Following the release of EEMS10.2, the DSI Team is busy developing exciting new features for the next version of EEMS….
Join Mr. Paul Craig, the chief developer of EFDC+ and EEMS to learn how domain decomposition and MPI can help speed up your EFDC+ model.
A primary function of EFDC+ is to solve the governing Partial Differential Equations (PDEs) for fluid flow and…
EEMS10 now has the ability to simulate spatially and temporally varying fields, such as a wind or barometric pressure fields.
