Erosion and sediment transport in the upper Tana catchment with special reference to the Thiba basin
Abstract
This thesis examines erosion and sediment transport problems
in the Upper Tana Catchment which covers an area of 9250 km. It
is based on a four-year field and laboratory study of erosion and
sedimentation processes in the drainage system.
The subject matter includes the assessment of hydrologic
and geomorphic processes responsible for soil erosion and sediment
transport within three land use types in the Upper Tana Catchment.
These include undisturbed forested areas, the cultivated regions and
the predominantly grazed areas. The study demonstrates how fundamental
the physical and human factors are to the operation of these processes •
Although a considerable number of studies of erosion and sediment
transport have been carried out in various parts of the world, very
few such measurements have been carried out in tropical countries.
No detailed work of this kind has been carried out in Kenya so far and
certainly not in the Upper Tana Catchment. The study does not
only deal with these processes but also demonstrates a methodology
that can be utilized in the assessment of sediment production rates in
r catchments and on hill slopes.
