ABSTRACT
It is worthwhile to recall an extract2 from the Report of the Mackenzie Committee (1962) in assessing hydro-electric potential in Scotland: ‘To have any real meaning, the estimates of potential water power must be related to economic considerations…’
Most published studies deal with Category (b), and, since regional investigations cannot by their nature deal with site-specific details and economic analyses, guidelines based on minima for flow and head have to be adopted.
