Streams fields
Descriptions of fields in the streams feature class.
GOID
Stream Identifier
ID is used to link the dam to the river reach
NOID
Network Object identifier

NDOID
Downstream network identifier
Down stream network identifier
NUOID
Upstream network identifier
Upstream network identifier
REACH_ID
Reach identifier
River reach identifier
LENGTH_KM
River reach length
Length of the river reach in kilometres
LENGTH_DOWN_KM

RIV_ORD
River Order based on field DIS_AV_CMS (Discharge / Flow)
River order is based on the long-term average discharge:
| 1 = > 100000
| 2 = 10000 – 100000
| 3 = 1000 – 10000
| 4 = 100 – 1000
| 5 = 10 – 100
| 6 = 1 - 10
HYFALL
Hydro falls
Indicates whether a waterfall is present.
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

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.
BB_OCEAN
Ocean connectivity
A binary field indicating whether the river is directly connected to the ocean (value = 1) or not (value = 0).
BB_LEN_KM
River length
Length of the river in kilometres.
BB_VOL_TCM
River volume
Volume of the river in thousand cubic metres.
BB_DRY_PCT
Dryness indicator
Indicator for intermittency (0 = flowing year long; 100: completely dry all year long)
