Barrier fields

Descriptions of the fields in the barriers feature class.

Field	Alias	Description
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)	The name of the field holding the storage capacity of the dam in million cubic meters (MCM). The name of the field can be different since the user specifies the desired field in the Degree of Regulation Settings.
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	Upstream discharge range factor values to be applied when calculating degree of fragmentation using dam-level discharge range factors. The name of the field can be different since the user specifies the desired field in the Degree of Fragmentation Settings.
DRF_DWN	Upstream discharge range factor	Downstream discharge range factor values to be applied when calculating degree of fragmentation using dam-level discharge range factors. The name of the field can be different since the user specifies the desired field in the Degree of Fragmentation Settings.
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.
