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)

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.
