Knighton, A.D. Local variations of cross-sectional form in a small gravel-bed stream
The local behaviour of selected cross-sectional variables is analysed for four stream lengths located at different positions along the profile of Cave Stream in the Southern Alps, New Zealand. Bankfull width and mean depth are correlated with stream bed height. Riffle sections are distinguished from pool sections in having wider and shallower channels. However, bed topography has little apparent influence on cross-sectional form as a spatial series. The series for the two upstream lengths are dominated by random effects and only in the downstream lengths where the stream becomes large enough to counteract external constraints does any degree of regularity in the variation of cross-sectional form begin to develop.
