Incomplete contents:
The evaluation of potential impacts of water resource development upon instream uses such as recreation and fisheries requires in the first instance a large amount of information on the character and environment of the river channels involved. A review of the various methods already in use for evaluating instream flow needs indicates, that, despite a wide diversity of approaches, there are many data requirements in common. Indeed, it is apparent that the intrinsic characteristics of a river may be described independently of the particular human use of concern; in principle, description of the physical appearance of a river is a relatively simple, though time-consuming, matter. A data collection procedure is proposed which will provide all the data needed by a specialist to assess the value of a given channel for instream uses. Data fall into the following groups; (i) Geographic location; (ii) Channel environment and setting; (iii) Channel hydraulic geometry; (iv) Sediment characteristics; (v) Streamflow and water quality; (vi) Riparian vegetation. As an example the procedure is applied to the Ashley River, Canterbury
