[GRASS-user] friendly hydrologic model for water availability

[Massimiliano Cannata]

Dear Marcello,
You are right, for some reason, some of the code in the grass addons is not
present anymore.
Probably, the evapotranspiration module has been moved in the trunk (
i.evapo.pm, see http://grass.osgeo.org/grass70/manuals/i.evapo.pm.html)
Also the code for r.hydrofoss is missing (I don't know why...). I will put
on the server as soon as I will be back in the office.

By the way, If I correctly understand your goials, I don't think that
hydrofoss is suitable for your scope.
It is far away from being a simple and fast module to get a rough estimates
of water availability regarding a basin.
Probably, some concentrate module, can be most suitable: using less
parameters and being more tested.

The calibration, can be tricky and it has to be done in both the case, so
you need a sufficient number of observations regarding river discharge in
at least one point along the rivers (possible at basin closure point).
HEC-HMS could be one options (
http://www.hec.usace.army.mil/software/hec-hms/index.html,
http://www.hec.usace.army.mil/software/hec-hms/documentation/HEC-HMS_QuickStart_Guide_3.5.pdf
)

I would suggest (if you can understand italian) to take a look at this
http://www.hydro.unibo.it/teaching/IRI/slides/07_ModelliIdrologici.pdf to
get a better idea of the different types of hydrological models and scopes
of each of the existing types (see slide number 3).

Please, let me know if anything is needed. i will try to restore the old
page related to HydroFoss in the REDME file.

Best regards,
Maxi
