Basin properties: Physiographic

The following map will display the aggregated physiographic information for each watershed in the database. The properties are derived from the HydroSHEDS (2006) dataset. The void-filled HydroSHEDS digital elevation model (DEM) with a 30 arcsec resolution is used and can be downloaded for free (here). The information was extracted with the PAVICS subsetting tools.

The map includes switches to display the following properties:

• latitude of watershed centroid [deg]
• longitude of watershed centroid [deg]
• area [km²]
• elevation [m]
• slope [deg]
• gravelius [frac]
• perimeter [km]
• aspect [deg]

The blended Raven model used for the hydrologic simulations used the properties of area, elevation, slope, as well as latitude and longitude of the watershed centroid.
