Summary
...
Sobek-CF schematization and a (perhaps already calibrated) Modflow schematization. |
...
He wants to calibrate this composition. |
...
He has 5 observations available (water levels time series at 3 Sobek-CF locations, grondwater level time series at 3 Modflow locations). |
...
The parameters that have to be calibrated are: |
...
- the Manning coefficient in a certain part of the river schematization |
...
- the exchange coefficient used for computing the seepage (coefficient is the same for all locations and all time steps). |
...
There is an algorithm available that, to do its work, must be able to repeatedly: |
...
- feed a new value for each parameter to the related model |
...
- ask the models for their computed values at the locations where the observations are available |
...
- compare (or let another component compare) the computed values and the observated values. |
...
We assume that both Sobek-CF and Modflow implement the IManagedState interface. h2. |

How to address in Version 1 |
...
You have to program two classes, the calibration algorithm itself, and a cost function. |
...
The cost function class: |
...
* can link the two models (i.e. that is a kind of 'Composition' class, and therefore preferably can be instantiated from an *.opr file) |
...
* can access the required parameters of the two models (note that this class has to be a ILinkableComponent itself). |
...
* is a ILinkableComponent itself (including IManagedState), so that another ILinkableComponent (the algorithm) can interact with it. |
...
The algorithm class: |
...
* is a ILinkableComponent itself, be able to interact with the cost function class |
