Appendix D - Inland Water Features Guide
1. Background, Description & Supply of the Digital Inland Water Features Guide
This guide originates from a guide produced by geographers in AUSLIG for inclusion in the SYMBAS 1988 Specifications, produced by the Royal Australian Survey Corps. The guide remains relevant and is the best available for the classification of inland water features. The major modification from the original guide is the combination of the intermittent and mainly dry water classifications into a non-perennial classification. This guide shows major perennial and non perennial watercourses and minor perennial watercourses only. Watercourses not shown on this guide will be classified as minor non-perennial except tidal watercourses in areas of mangrove which are always to be shown as perennial.
