8. Run PIHM
RunPIHM is the module where PIHM has
been integrated to Qgis. For a successful run of the model is required to have
all the input files prepared in accordance with the file format of the PIHM. It
should be noted that PIHMgis helps prepare only 4 files out of the 8 files
needed for a model run.
In the input section of the dialog
browse the folder where the input files for the model has been stored. The model
assumes that each input file has the same first syllable for the file name
followed by “.” and file type (for e.g. domain.mesh; domain.att; domain.soil).
Input File ID corresponds to that first syllable of the input files (for the
“domain” example - input domain in
the Input File ID textbox). Click RUN to begin processing. The
interacting hydrologic processes of different timescales introduce stiffness
into the system of ordinary differential equation. Therefore, the time a model
run will take to complete depends on several factors which include: simulation
duration, forcing data, system state. A progress-bar has been provided to keep
track of progress of the simulation. After the completion of the model run Close the
dialog.
