Re: [Qgis-user] River Flood modelling
Hi Nicolas and Jonathan, and not to forget Whitebox as extra hydrological software the results of which may be imported: http://www.uoguelph.ca/~hydrogeo/Whitebox/ Thomas Am 25.01.2019 um 23:54 schrieb Jonathan Moules: Hi Nicolas, If you don't get a reply here that solves your issue it may be worth asking on the GRASS mailing list.

I am looking for something like the Saga Lake flood module with a LiDAR derived DEM, a seed but with the possibility to add X amount of water. It's basically a lake and dam scenario and you just add water and figure out where the water goes down the valley when it goes over the dam. Of course I can't use the normal lake flood modules because rivers are not flat therefore I need something that takes the downhill valley shape into consideration. Also, I am not looking for a simple channel network map with lines and points. I would like the actual polygon or raster representation of the 2D shape of the river channel. Can you please point me in the right direction.

Re: [Qgis-user] Eliminate GAPS SRTM 30 metros
-BEGIN PGP SIGNED MESSAGE- Hash: SHA512 Hi, ALOS World 3D - 30m (AW3D30) data may be also considered an alternative (http://www.eorc.jaxa.jp/ALOS/en/aw3d30/), for the time being already available for substantial parts of Southern Asia and South America. Informations on how resolution and error margins of the dataset compare to ASTERDEM or SRTM30 will be appreciated.

Re: [Qgis-user] SRTM-plug-in?
-BEGIN PGP SIGNED MESSAGE- Hash: SHA512 Hallo all, anyway the "Retrieve SRTM DEM data" tool of the (very versatile) Whitebox GAT http://www.uoguelph.ca/~hydrogeo/Whitebox/ software has it, with options to mosaic and data hole filling, see notes to the module with Python and Groovy script examples. Both resolutions are supported.
