Detailed_Description:

Entity_Type:

Entity_Type_Label: riv_hydro1k

Attribute:

Attribute_Label: FID

Attribute_Definition: Internal feature number.

Attribute_Definition_Source: ESRI

Attribute_Domain_Values:

Unrepresentable_Domain:: Sequential unique whole numbers that are automatically generated.

Attribute:

Attribute_Label: Shape

Attribute_Definition: Feature geometry.

Attribute_Definition_Source: ESRI

Attribute_Domain_Values:

Unrepresentable_Domain: Coordinates defining the features.

Attribute:

Attribute_Label: LENGTH

Attribute:

Attribute_Label: FLOWACC
Attribute_Definition:: The maximum flow accumulation value of the stream segment. This value corresponds directly with the upstream watershed contributing area. (10-3 km2)

Attribute:

Attribute_Label: PF_TYPE
Attribute_Definition:: The Pfafstetter level at which the stream segment is considered “main stem”

Attribute:

Attribute_Label: LEVEL1
Attribute_Definition: The Pfafstetter units in which the stream segment lie.

Attribute:

Attribute_Label: LEVEL2
Attribute_Definition: The Pfafstetter units in which the stream segment lie.

Attribute:

Attribute_Label: LEVEL3
Attribute_Definition: The Pfafstetter units in which the stream segment lie.

Attribute:

Attribute_Label: LEVEL4
Attribute_Definition: The Pfafstetter units in which the stream segment lie.

Attribute:

Attribute_Label: LEVEL5
Attribute_Definition: The Pfafstetter units in which the stream segment lie.

Attribute:

Attribute_Label: LEVEL6
Attribute_Definition: The Pfafstetter units in which the stream segment lie.

Attribute:

Attribute_Label: FRMELEVATI
Attribute_Definition: The elevation value of the stream segment’s from-node (m)

Attribute:

Attribute_Label: TOELEVATIO
Attribute_Definition: The elevation value of the stream segment’s to-node (m)

Attribute:

Attribute_Label: STRORDER
Attribute_Definition: Strahler stream order of the segment

Attribute:

Attribute_Label: GRADIENT
Attribute_Definition:: Gradient of the stream segment calculated as the difference of the from and to-node elevations divided by the length of the segment

Attribute:

Attribute_Label: FRMUP_FLOW
Attribute_Definition:: The upstream flowlength from the from-node. Calculated using ARC/INFO’s FLOWLENGTH function, it is the longest path from the from-node to the drainage basin divide. (m)

Attribute:

Attribute_Label: TOUP_FLOWL
Attribute_Definition: The upstream flowlength from the to-node. (m)

Attribute:

Attribute_Label: FRMDN_FLOW
Attribute_Definition:: The downstream flowlength from the from-node. Again from ARC/INFO’s FLOWLENGTH function, it is the length from the from-node to the ocean or a terminal sink. (m)

Attribute:

Attribute_Label: TODN_FLOWL
Attribute_Definition: The downstream flowlength from the to-node. (m)

Attribute:

Attribute_Label: SOURCETHM
