Abstract: | The impact of urbanization on stream channels has been investigated in a range of areas; the degree and extent of the channel
adjustments have been demonstrated; and for a few areas these characteristics have recently been placed into a spatial context.
A method of rapid field survey for depicting the channel network of urban areas in terms of near natural, adjusted, and channelized
systems is illustrated for the urban area of Armidale NSW, for which Armidale Dumaresq Council had prepared a stormwater management
plan. Such a survey could enable channel characteristics and adjustments, as well as water quantity and quality, to be included
in the management plan. Possible options for management to address are suggested for each of the channel categories. A channel
classification system of the kind suggested can provide a basic complement for the further development of the stormwater management
plan, can afford a basis for specifying management alternatives, and can be helpful in demonstrating the options offered for
community consultation. |
