implementation steps
We will implement running of Sobek through a dll using the following approach:
Extend fortran code to allow for setting model parameters and data (ie "setvalues")
In C# the module wlacces implements running of sobek models that are defined in a file.
setvalues will be defined in new interface (not in iwlaccess !)
fortran c / code will implement methods in interface
Type Network
[Test]
public void RunSobek()
see similar implementation for modflow
examples
- MODFLOW wrapper example, checkout https://openmi.svn.sourceforge.net/svnroot/openmi/branches/OpenMI-1.4.1-dev and check MyOpenSource\Wrappers\src\USGS\MODFLOW.
- Existing SOBEK OpenMI wrapper: http://svn/repos/ds/trunk/previous/openmi_wrapper
Notes
- Sobek OpenMI module:
Useful function for initialising and performing one or more timesteps and finalizing.
-
- 'SE_OpenMI.f90' communicates with OEM buffer.
- 'SE_OpenMI.f90' has calls to module OMI_CF_control in (OMI_CF_control.f90), which in turn calls directly sobeksim subroutines
- Present SOBEK reads nefis files during initialisation (using m_nefisinput.mod). Nefis is used in subroutines: read_initial_values_strpar_etc, soedef, sogetm and wetcrs.
SOBEK variables read from NEFIS

integer, allocatable :: trcnrl(:,:) ! trigger controller relation (mxtrcnrl,ntcrel) integer, allocatable :: cnstrl(:,:) ! controller structure relation (mxcnstrl,ncsrel)
Q2: Engelund-Hansen parameters - isn't it morphology? is it required for flow
Q3: Give definition of a structure, controller, trigger and give full list of their parameter names.
Q4: Cross-section type currently of two types - describe them
- free form
- wetted-perimeter formula
