| 109 | African to USGS-style quaternary codes.\r\n(mainly of interest to ESA | ||||
| 110 | BASINS users).\r\nWRIALL500.AVL: legend file for ArcView 3.x - line | ||||
| 111 | width proportional to Strahler | ||||
| 112 | order.\r\n-----------------\r\nWRIALL500.PRJ: ESRI projection | ||||

| 124 | TMPRIV_, TMPRIV_ID.\r\n\r\n(2) ATTRIBUTES (sequence may differ)\r\n. | ||||
| 125 | ==========\r\nNAME: generally, the name assigned to the reach on a | ||||
| 126 | topographical map\r\n- sometimes the correctness is uncertain.\r\n- | ||||
| 127 | ALIAS: alternate name or names for the reach, separated by \\.\r\n- | ||||
| 128 | RIVN_ROOT: For multilingual annotation purposes (prototype): the root | ||||
| 129 | of the river name.\r\n- RIVN_SUFX: The qualifier of the river name, | ||||
| 130 | e.g. river, spruit, loop.\r\nCLASS: unreliable indicator of | ||||
| 131 | seasonality of river flow. The classes and allocation require | ||||
| 132 | review:\r\n- Dry=dry river, Perennial=perennial river, | ||||
| 133 | Non=non-perennial river,\r\nUnknown=not present in original coverage | ||||
| 134 | or not transferred from source map.\r\nPRIMARY: primary drainage | ||||
| 135 | region where the reach occurs.\r\n- a lower-case letter indicates a | ||||
| 136 | pseudo drainage region outside South Africa.\r\nORDER: Strahler order, | ||||
| 137 | starting from source=1.\r\nEND: S=Source, N=iNtermediate, M=Mouth, | ||||
| 138 | E=Endorheic.\r\nREACHCODE: 10-character reach code made up as | ||||
| 139 | follows:\r\n- 1 to 4: quaternary drainage region in which MOST of the | ||||
| 140 | river falls.\r\n(Note that USA programs such as BASINS expect eight | ||||
| 141 | numerical digits.\r\nThe qat4qat8.txt lookup table contains the | ||||
| 142 | appropriate DWA to USA conversions.)\r\n- 5 to 6: arbitrary sequence | ||||
| 143 | number of the reaches within a quaternary drainage region.\r\n- 7 to | ||||
| 144 | 10: four zeroes (0000) in the 1:500 000 coverage, intended for later | ||||
| 145 | use at more detailed scale.\r\nSORTER: internal sorting field - always | ||||
| 146 | increases downstream in river network\r\nLENGTH_KM: length of reach | ||||
| 147 | in kilometres (not to be confused with the meaningless LENGTH | ||||
| 148 | field).\r\nRivEX fields: (see http://www.rivex.co.uk/)\r\n- SEGMENT : | ||||
| 149 | Channel identifier.\r\n- STRAHLER: Horton-Strahler order.\r\n- | ||||
| 150 | SHREVE: Shreve order.\r\n- US_ACCUM: Accumulated upstream metres at | ||||
| 151 | the lower node of each arc.\r\n- LINK_TYPE : same idea as the \"END\" | ||||
| 152 | field, above. E=Exterior, I=Interior, O=Outlet.\r\n- CATCHID: | ||||
| 153 | Automatically generated ID for each end node (i.e. when END='E' or | ||||
| 154 | 'M').\r\n- DIST2MTH : Distance to the mouth in metres from the upper | ||||
| 155 | node of each arc.\r\n- MAINCHAN : Main channel identifier.\r\n- | ||||
| 156 | CATCHID : drainage region identifier.\r\n", | ||||
