Attributes associated directly with network:
Field | Type | Description |
Catarea | Real | Watershed area in m2 |
CUM_Area | Real | Area upstream of a reach (and including this reach area) in m2. |
Nzsegment | Integer | Reach identifier to be used with REC2 (supercedes nzreach in REC1). |
nz_fnode | Integer | Unique number of preceding river segment's outlet node. |
nz_tnode | Integer | Unique number of following river segment's inlet node. |
Lengthdown | Real | The distance to coast from any reach to its outlet reach, where the river drains (m). |
Headwater | Integer | Number (0) denoting whether a stream is a “source” (headwater) stream. Non-zero for non-headwater streams. |
Hydseq | Integer | A unique number denoting the hydrological processing order of a river segment relative to others in the newtork. |
StreamOrder | Integer | A number describing the Strahler order a reach in a network of reaches. |
euclid_dist | Real | The straight line distance of a reach from the reach “inlet” to its “outlet”. |
upElev | Real | Height (asl) of the upstream end of a reach section in a watershed (m). |
downElev | Real | Height (asl) of the downstream end of a reach section in a watershed (m). |
upcoordX | Real | Easting of the upstream end of a river segment in m (NZTM2000). |
upcoordY | Real | Northing of the upstream end of a river segment in m (NZTM2000). |
downcoordX | Real | Easting of the downstream end of a river segment in m (NZTM2000). |
downcoordY | Real | Northing of the downstream end of a river segment in m (NZTM2000). |
sinuosity | Real | Actual distance divided by the straight line distancegiving the degree of curvature of the stream |
nzreach_rec1 | Integer | The REC1 identifiying number for the corresponding\closest reach from REC1 (can be used to retrieve the REC management classes) |
headw_dist | Integer | Distance of the furthermost “source” or headwater reach from any reach (m). |
Shape_length | Real | The length of the reach (vector) as calculated by ArcGIS. |
Segslpmax | Real | Maximum segment slope along length of reach. |
Segslpmean | Real | Mean segment slope along length of reach. |
LID | Integer | Lake Identifier number(LID) of overlapping lake. |
Reachtype | Integer | A value of 2 is assigned if the segment is an outlet to the lake, otherwise 0 or null. |
nextdownid | integer | segment number of the most downstream reach |
