Abstract

Small-scale aerial photographs and high-resolution satellite images, available for Ethiopia since the second half of the twentieth century, allow only the length of gullies to be determined. Understanding the development of gully volumes therefore requires that empirical relations between gully volume (V) and length (L) are established in the field. In this study, V–L relations were established for permanent gullies in northern Ethiopia. In order to take the regional variability in environmental characteristics into account, factors that control gully cross-sectional morphology were studied from 811 cross-sections. This indicated that the lithology and the presence of check dams or low-active channels were the most important controls of gully cross-sectional shape and size
