I was having some trouble in finding the format required for the sediment core .dat file needed for setting the initial bed conditions under ‘Sediment and Sediment Bed Properties’ window, in the tab ‘Initial Conditions’ under ‘Initialization of Sediment Beds’
For the ‘Tra Khuc Sediment Transport’ example, the file required to define the bed is ‘Soil Analysis Data.dat’. I thought it would be useful to post the following information regarding the definitions for the cells in the file. The file gives the following information, and based on my best judgement the corresponding definitions are shown below. If there is a mistake in these definitions please let me know.

Hi there. The information of sediment core data file format can be find in the User Manual at the page 235, Data Format B-4 https://eemodelingsystem.atlassian.net/wiki/spaces/EEREF/overview Here is the format description, Data Format B-10 Sediment Cores with Grainsize DSM FormatThe “Sediment Cores with Grainsize” Digital Sediment Model (DSM) format is file that contains any number of cores. Each core can have any number of samples at depths below the top of the core. For each core the user must locate the core in horizontal (XY) space. The “Z” requested is the top of the core elevation (i.e. the bottom elevation at the core location). Title Line “Discrete” Flag: Used to determine data file format Loop over groupings of cores (Loop Terminated by the “END” statement) ID, #Cores X Y Z #Depths Loop over #Depths Thickness, Porosity, SpecGrav, nFractions Loop over nFractions Max Grainsizes (um) EndLoop Loop over nFractions %Finer EndLoop EndLoop END --> End Core Definitions with an “END” Regards, // Tinh
Great, thanks. This is very helpful.
