Relationships between the morphometric parameters of meander planform in south County Down

James M. O'Boyle


Dynamic adjustments to achieve quasi-equilibrium in alluvial streams involve changes in the planimetric geometry. To determine the present situation in South Down, detailed field measurements of meander elements were made on a sample of fifty river meanders, forty-six of which occur on slopes of less than 2°.

Significant relationships were established between channel width and meander wavelength, radius of curvature, amplitude and meander-belt width as dependent variables. These relationships were found to be curvilinear, thus indicating that ratios are not constant. Correlation coefficients for paired planform elements were calculated. Relations were similar to those of other recent empirical studies.
