Descriptions of the fields in the barriers feature class.
GOID
Stream identifier
Corresponds to the GOID of the nearby river. For the model to recognize on which river the barrier is located, each dam must have the correct GOID value (i.e., the GOID that corresponds to the GOID of the river reach).
NOID
Network identifier
Corresponds to the NOID of the nearby river. The value in this field should match the NOID value of the river reach in the streams feature class where the barrier is located.
STOR_MCM
Storage capacity of the reservoir in million cubic meters (mcm)
INC
Dams to include
A binary field (0 or 1) indicating whether to include the barrier (value = 1) or exclude the barrier (value = 0) from the analysis.
DRF_UP
Upstream discharge range factor
DRF_DWN
Upstream discharge range factor
BAS_NAME
Hydrological Basin name
Based on HydroSHEDS original basins.
BAS_ID
Hydrological Basin identifier
An integer identifying the hydrological basin the barrier is in. Values should be the same as the BAS_ID for the river the barrier is in.
BAR_ID
Barrier identifier
An integer identifying the barrier.
BAR_NAME
Barrier Name
Provides the name of the barrier, if available.
BAR_Type
Type of barrier
Indicates the type of barrier (e.g., irrigation, hydropower, water supply, etc.).
LONG
Longitude
The longitude of the barrier.
LAT
Latitude
The latitude of the barrier.
STAGES
Stage of development
Indicates whether the barrier is existing (value = ST1), under construction (value = ST2), or planned to be constructed (value = ST3).
RIV_ORD
River order
The river order of the stream where the barrier is located. The values in this field should match the values of the field in the streams feature class for the river reach where the barrier is located.
DIS_AV_CMS
Long-term average discharge
The long-term average discharge measured in cubic metres per second.
HYDRO_LAKE
Lake identifier
An integer identifying the lake/reservoir associated with the barrier. The identifier for the lake/reservoir should match lake feature class.
PCAP_MW
Power capacity in megawatts
The power capacity of the barrier measured in megawatts. Can be used as an alternative to storage volume (STOR_MCM) if storage volume is unavailable. Based on the power of the dam, a rough estimate of reservoir size can be derived.
YEAR
Year of construction
The year the dam was constructed.
STATUS
Status of development
Indicates whether the barrier is existing (value = EXI), under construction (value = CON), or planned to be constructed (value = PLA).
INC1
Alternative dams to include
A different dam inclusion field for running the analysis with a different set of barriers. In this case, INC1 includes existing dams only. Can be used to calculate new values for testing different scenarios.
INC2
Alternative dams to include
A different dam inclusion field for running the analysis with a different set of barriers. In this case, INC2 includes existing dams and dams that are under construction. Can be used to calculate new values for testing different scenarios.
INC3
Alternative dams to include
A different dam inclusion field for running the analysis with a different set of barriers. In this case, INC3 includes existing dams, under construction dams, and planned dams. Can be used to calculate new values for testing different scenarios.
GRAND_ID
GRAND identifier
The GRAND database identifier.
KCL_ID
KCL database identifier
The KCL database identifier
Zarfl_ID
Zarfl identifier
The zarfl database identifier.
SOURCE
Data Source
Indicates the source of the data.
BB_ID
Backbone river identifier
An integer identifying on which river the barrier is located. The values in this field should match the values in the streams feature class for the river the barrier is located on.
BB_LEN_KM
River length in kilometres
The length of the river in kilometres. The values in this field should match the values in the streams feature class for the river the barrier is located on.
Region
Region
The region where the barrier is located.
