First of all, general parameters.
Note: This state parameter here is used in step 5 of the Global check!
Secondly, the detailed model needs some extra parameters.
The probabilistic parameters are fixed,Only the Mean "Area ratio" can be changed (white box)
Global and Detailed assessment method.
Input screen for the 5 sets of parameters: Water, Revetment, Foreland, Soil and Influence zone
NOTE: The state parameter Ψ5m entered here is used in the Detailed check.

5.2 Revetment (Global assessment method)
Name in English | Name in Dutch | Description | Symbol | Unit | Default + decimals + (range)
|
---|---|---|---|---|---|
Revetment length dike top | Bekledingslengte vanaf buitenteen dijk | Horizontal projection of the length of the revetment, starting at dike toe at river side. | Mbestorting | m | 0.00 (0-10000) |
RX start bottom revetment | RX start vanaf geulbodem, onderste gedeelte van vooroever | Start co-ordinate of the revetment at the bottom of the channel. | Xstart;bestorting;onder | m | 0.00 (-10000-10000) |
Bottom revetment length | Bekledingslengte onderste gedeelte van vooroever | Horizontal projection of the length of the revetment at the bottom of the channel. | Mbestorting;onder | m | 0.00 (0-10000) |
5.3 Foreland (Global assessment method)
In case of non-natural deposited slopes, both Global and Detailed checks FAIL and it should immediately be switched to the advanced methods.
Name in English | Name in Dutch | Description | Default |
---|---|---|---|
Artificial and non-densified sandy foreland? | Is er sprake van een kunstmatig onder water aangebrachte en niet verdichte zandige of siltige vooroever? |
| No |
5.4 Soil (Global and Detailed assessment method)

---|---|---|---|
State parameter Psi 5m | State parameter Psi 5m | Parameter describes the state of the soil and is used in the Detailed check. | 0.0000 (-10-10) |
Sand type (particle size) | Zand type (korrelgrootte) | Parameter describes the type of sand and is used in the Global check (breach flow criteria is step 1e). Three types of sand are considered:
| Fine sand |
5.5 Distance dike toe/influence zone
Name in English | Name in Dutch | Description | Default |
---|---|---|---|
Distance dike toe / | Afstand buiten dijk / invloedslijn | Parameter describes the distance between the dike toe and the boundary of influence zone. it must always be less than the foreland length. | 0.00 (0-foreland length) |
