SOME ENGINEERING PROPERTIES OF UDZUNGWA SCARP SOIL

The Udzungwa scarp is prone to landslide, slope instability, and severe erosion brought about by several interrelated factors like rainfall, soil geological formation, geomorphological feature of the slope and gross engineering properties of the soil available within the scarp. In this paper, some engineering properties of soil available within the scarp are discussed. Various soil engineering characteristics, erosion, and slope stability problems are pinpointed and discussed. This paper is based on the study carried out during pre-construction, construction, and post-construction investigation of 16 Km of Kihansi Dam Access road, which is traversing the Udzungwa escarpment.
