Morphometric analysis of drumlin fields in northern Central Europe

An attempt is made to analyse the differences in characteristics and interrelations of drumlin fields in twelve areas in northern Central Europe. Measurements of size, shape, orientation, and distribution of drumlins have been made, using 1:25,000 topographic maps with contour patterns at 1.25 m intervals. Four groups are suggested according to the mean size of drumlins. A classilkation of drumlin shape is suggested according to the width‐length ratio. Average drumlins are either elongated or ventricular. Variation of the drumlin orientation possibly indicates the complexity of the ice movement. The distribution of drumlins is examined by using nearest‐neighbour analysis. Significance of the differences between drumlin fields is determined by using analysis of variance. Four different groups of drumlin fields arc suggested by using cluster analysis. The method proved suitable for a systematic analysis of geographical features in the landscapes of this type.
