The sediment parameters form with the Initial Conditions tab selected is shown in Figure 2.
- Select Spatially Varying Bed Conditions; Specify Mass Fraction and click on Assign Bed IC
- In the new window, select Use Sediment Cores with Grainsize (Figure 3)
- Browse to the sediment core file data e.g "TrakhucTra_Khuc_Sed_Cores.dat"
- Define Max diameter of grains, Number of Initial Layers, Minimum Layer Thickness
- Click Apply and a form summarizing the imported data is displayed as shown in Figure 4, click the "Exit" button
- Click OK button in the form of Figure 3 and Figure 2 to finish.
- Figure 5 shows the initial conditions of sediment bed in 2DH View
...
- In 2DH View, select Import an External Overlay Layer
under Layer Control (Figure 6) - The Open External Layer window will appear (Figure 7). Choose Sediment Bed Cores (*.dat) from the drop-down list then browse to the sediment core file data e.g "TrakhucTra_Khuc_Sed_Cores.dat"
- A new Sediment Bed Core layer will appear, select this layer and ensure the edit function
is on. RMC on any cell and select Create New Bed Core (Figure 8).

Sediment core data that has been analyzed and summarized may be used to manually update the core field. From the data set available the user can extract the information then fulfill in the form as shown in Figure 9. This requires the following steps:
...
Now a the sediment core data file has been built and we can set initial condition for sediment as shown in Figure 3.
