Gullying within wetlands in Zimbabwe : morphological characteristics of gullies

Auteur :
WHITLOW, R.

Description :
The morphology of dambo gullies is examined with particular reference to ten gully systems in the Chikwakwa-Mangwende area in north-east Zimbabwe. Localised piping is related to clay-rich, slightly sodic subsoils in columnar dambo profiles, while deep hexagonal cracking is prevalent in the smectitic dambo clays and affects crumbling of gully banks. - (AJC)
