[GRASS-user] friendly hydrologic model for water availability

GRASS GRASS user
1

Hello all,

I’m interested in getting my water availability basin, using a model that is as simple to use, the goal is to estimate the volume available to the basin water users (grantable volume).

Thus, it makes sense to use a complex model, such as the r.topmodel, could someone indicate some module or addons for GRASS?

Thanks in advance,

Here is an overview http://grasswiki.osgeo.org/wiki/Hydrological_Sciences
Of course the choice of the most appropriate tool mostly depend on the data available and on the accuracy of the results that you aim to achieve.

Hello mag,

Thanks for your quick reply, definitely do not need anything very precise, just an idea of magnitude values.

I think HydroFOSS interesting, but unfortunately the site is down, I´ll try to contact the author.

Again, Many thanks for your help,

Hi Markus,

I referred to the link that is inside the README (http://istgis.ist.supsi.ch:8001/geomatica/index.php?id=1).

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
