Summary
The end user combines a (perhaps already calibrated) 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

...
- compare)
...
- the
...
- computed
...
- values
...
- and
...
- the

- observated
...
- values.

We

assume

that

both

Sobek-CF

and

Modflow

implement

the

IManagedState

interface.

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:
