The basic of the program is the Surface line.
The user has to create a surface line with ascending x-value from channel side of the embankment till the dike top at the polder side.
You can re-order the points, ascending or descending, by clicking on the table header L(enght) of Z(height level)
You get the real order the point, as shown in the drawings, by "Ctrl + click"
It is not impossible to enter a malformed geometry.
The riverside has to be on the left side
The riverside has to be on the left as shown in the figure below.
The original surface line as used in DAM or Ringtoets (WTI) contains a whole set of characteristics points. Flow Slide needs a subset.
Please enter your Surface line by using points B, C, D, G and J
The The following 5 characteristics points are obligated in the order 1 till 5 with ascending XD-FlowSlide with increasing x-value.
- Bottom river channel (B)
- Insert river channel (C)
- Dike toe at river (D)
- Dike top at river (G)
- Dike top at polder (J)
Please enter your Surface line according this picture
The description of these parameters can be found on the page Input parameters.
Input screen for the coordinates L and Z and the characteristic points
You may, of course add additional points to describe the real surface line.
By clicking on the table header L(enght) of Z(height level), you can only filter the points, but not order them.
The program checks on a malformed surface.
