Using EFDC Explorer to compare bathymetry between different models

Often times we will end up having two different bathymetry data sources and we would like to know how different those data sources are. Eventually, we will use those data to create bathymetry in EFDC model.

EFDC model allows an easy comparison between bathymetry at two different models.

For example, we will use an EFDC model of Ohio River which can be downloaded fromĀ EFDC Explorer website Continue reading


How to create P2D file in EFDC Explorer

If you do not have the shape file of the area you are working on then you might have difficulty to create the polygon file that can be used to create the grid.

However, you can use the following tools to create the p2d file to use in EFDC Explorer.

Using EFDC Explorer to Set up the EFDC

EFDC Explorer, a pre processor and post processor developed from Dynamic Solutions can be used to faciliate the model input preparation, analysis, calibration etc. There are three versions of EFDC Explorer. They are Web version (free and hydrodynamic part only), trial version (30 days trial with full functions integrated) and full version (hydrodynamic, sediment transport and water quality).

Recently, a latest version of EFDC Explorer is released and the version is EE 6.

You can download EFDC Explorer on this website:

You can ask several EFDC related and EFDC Explorer related questions on their forum. However, the response from the forum is pretty slow.

Another advantage of using EFDC Explorer is that you can create the simple grids easily and you can import the grid created from several third party softwares.

I hope your simulation process gets rolling.

If you know any other non-commercial software or commercial software that can be used to pre process and post process EFDC model, please write in the comments.
