River basins of Vorarlberg rivers

This dataset includes almost all catchment areas of all rivers, streams, trenches and mobs present in our digital river network.
The catchment area at the point of estuary of a river is defined as the area which, if the surface of the site is completely sealed, drains after all existing sinks have been filled by this point. In particular, this catchment area also includes all those areas that in reality would drain out of the catchment area due to underground flow processes or technical facilities. In other words, these are purely topographically defined catchment areas.

Important fields and data types of the attribute table (those that contain content information):
fgw_id unique identifier of the waterway route (e.g.: 812260)
Order Order Order (Rhine ... 1, Ill ... 2, Garnerabach ... 3, ...)
Area_m2 catchment area size [m2]
Areakm2 Catchment area size [km2]
Order Order Order (Rhine ... 1, Ill ... 2, Garnerabach ... 3, ...)
Z_Max. height in the catchment area [m]
Z_Mean mean elevation in the catchment area [m] (median)
Z_min min. height in catchment area [m] – height of pour point
FGW_ID_LON unique identifier of the waterway route (e.g.: 81 22 60)
NAME_MUEND Water name at the mouth

Data up-to-dateness:
The river basins within Vorarlberg are based on the ‘digital elevation model from 2011’ and the ‘water network 2017’. If there are major changes to the flowing water geometry or errors are detected, the affected catchment areas are recalculated.
