| dc.description.abstract | The Iringa area, situated in the Southern Highlands of Tanzania, exhibits various types of gully erosion and gullies form an important element in the landscape. They occur mainly on land which has been or could be used for agriculture and therefore contribute a great deal to land wastage, as well as to the silting of culverts and drainage channels in the area. The factors leading to soil erosion in the area are described and are identified as strongly seasonal rainfall, the presence of impermeable horizons at or near the surface, improper methods of Land use and increasing pressure on the land. Six specimen gullies mapped in the field on a scale of l:1200. The basis of morphology, topographic location and of material into which cut. Local land use history was also considered. On the basis of these studies and experience gained from a more examination of many other gullies in the area, characteristics of the gullies are described and an attempt made to analyse the origin, growth and age of the gullies. It is concluded from these that Bullying in the area is not the result of any process, but to the interaction of a number of both active and passive processes. It is further suggested that gullies in the area are not of recent origin, but that at present they are undergoing a renewal of erosion. It is considered that the cutting of the gullies is the result of more than one phase of activities. | en_US |
