Using fractal geometry to make rapid field measurements of riverbed topography at ecologically useful spatial scales
journal contribution
posted on 2023-05-16, 13:38 authored by Robson, BJ, Chester, EJ, Leon BarmutaLeon BarmutaA method is described for making rapid in situ field measurements of riverbed topography over spatial scales of-1-10 m. This method uses rolling balls to make quick, accurate measurements of river-bed roughness at several spatial scales. Random sampling and replication generate multiple estimates of the fractal dimension (d) that can be used to test for significant differences in the complexity of riverbed architecture between habitat types and spatial scales.
