7. Calculation and Results

Perform a calculation and the results will be displayed

When all parameters have been specified, you can start the calculation by using the blue arrow-head  or press the key F9.

If one of the parameters is out of range or missing, a validation message will be given in the table window "Validation messages"

When no errors are found, the results are presented in the window "Results"

In this version there is no extended report of the results.

7.1 Overall results

In this case both the global check fails and detailed check passes. However, since a very fine sand was selected, the  detailed check is formally not applicable. For this reason the overall result is not "pass". 

As a resullt of the calculation three charts are shown:

1. The Global assessment, solely based on geometric characteristics of under water slope and levee, fails. The leftmost chart visualizes the check whether a flow slide leads to unacceptable damage to the levee (step 1a). On the assessment level (horizontal dotted line), the actual slope lies landward of the assessment profile (green dotted line). This means that a flow slide does lead to unacceptable damage to the levee.

1. The middle chart shows whether a breach flow slide may occur or not (step 1e). A breach flow slide can occur if the actual slope lies landward of the green dotted line. 

1. The rightmost chart visualizes the results of the detailed check, in which also soil properties are taken into account. The red dotted line shows the profile after flow slide occurred, corresponding with a probability given in the tab with the detailed results (in this case 8.88E-05). In this case the calculated probability is smaller than the acceptable probability.

However when the detailed check is not passed, the advanced models can be used for further analysis of the problem. In the folowing paragraph the input data of the advanced models are explained
