DIS_AV_CMS | River reach discharge | The long-term average discharge in cubic metres per second. |
VOLUME_TCM | River reach volume | Volume of the river in thousand cubic metres. |
Source | Source | A binary field identifying the reach as a source reach (value = 1) or not a source reach (value = 0). |
Sink | Sink | A binary field identifying the reach as a sink reach (value = 1) or not a sink reach (value = 0). |
WIDTH_M | River reach width | The width of the river reach measured in metres |
Depth_M | River reach depth | The depth of the river reach in metres. |
INC | Rivers reaches to include | A binary field indicating whether to include (value = 1) the river reach or exclude (value = 0) the river reach from the analysis. |
CONTINENT | Continent name | Delineated based on HydroBASINS |
CON_ID | Continent identifier | An integer to identify the continent where the river reach is located. |
ISO_NAME | Country name | ISO country name |
ISO | Country code | The ISO country code. |
PAC | Protected Area | A binary field indicating that river reach is flowing through protected areas. |
BAS_NAME | Hydrological Basin name | Based on HydroSHEDS original basins |
BAS_ID | Hydrological Basin identifier | Based on HydroSHEDS original basins |
BB_NAME | River name | The name of the backbone river. |
BB_ID | Backbone river identifier | The identifier of the backbone river. |
BB_ORD | River order | The river order based on Hack’s stream order. |
BB_DIS_ORD | Backbone Discharge Order | Backbone discharge order calculated as RIV_ORD at last reach of river. |
