Image number: 2099
Feature : gully
Grouping : mass movements
Discipline : geomorphology
Year : 2007
Locality : Mutanga-Bujumbura
Country : Burundi
Region - tribe : Bujumbura
Physiographic region : Rift-Tanganyika
Notice : Upslope from the Lyceum 'Clarté de Notre-Dame' à Mutanga, a deep lavaka-like gully is developed more or less perpendicular to the slope. The gully has been deepened considerably during the last 50 years as a result of increasing peaks. The unusual location of the gully does rise the question whether a first ditch has not been digged around the lyceum ground in order to protect it against runoff from upslope. Anyway the deepening of the gully has initiated earth slides which affect now also the lyceum ground.
