1. Introductory Course Delft3D-QUICKIN
Bathymetry schematisation
Deltares

2. General strategy generation, manipulation of FLOW bathymetries
stepwise bathymetry generation
Use a polygon to select your working area. All operations apply to the area inside this polygon
high quality data (samples) first
various interpolation options
various viewing options
bathymetry manipulation
generation of non-uniform roughness or other parameter

3. QUICKIN - File

4. QUICKIN - Operations
Dependent on resolution of sample points versus grid cell size
A method to fill in depths if samples are insufficient

5. Example of detailed coverage

6. Example of poor coverage

7. QUICKIN – View (1)

8. QUICKIN – View (2)
Set Time step for Courant numbers in Settings – General

9. QUICKIN – Settings (1)

10. QUICKIN – Edit (1)

11. QUICKIN – Edit – Shortcut keys
C change sample value
D delete (polygon, depth or sample) point
E* delete polygon
I insert (polygon or sample) point
R replace (polygon or sample) point
X* break up polygon
* keep pressed

12. QUICKIN - AddSubDel To transfer depths to another grid
To use Operation – Triangulation

13. QUICKIN – Settings (2)

14. Example (overall)

15. Example (detail)

16. Generation of other attributes files
roughness file
dry points, thin dams, observation points, dredge and dump areas
Also with Visualisation Area FLOW-GUI
Deltares

17. Hands-on Delft3D-QUICKIN
build the bathymetry by working with sub-areas
start with ‘best’ data first
grid cell averaging when resolution samples > resolution cells
triangulation when resolution samples < resolution grid cells
fill in gaps with diffusion or triangulation (first copy depth to sample points)
save intermediate bathymetries
