Abstract
Temporal changes of sediment dynamics
within the Nairobi River sub-basins between
1998–2006 time scale, Kenya. The city of Nairobi
is the heart of both industrial production and the
economic hub in Kenya and the Eastern Africa
region. The city of Nairobi and its environs are
drained by three streams, namely: Nairobi, Mathare
and Ngong rivers. These streams drain areas of
diverse land use activities. The land use changes
in a spatial manner from the rich agricultural system
through residential cum urban to industrial.
The signifi cance of these various land use systems
to pollutants generation, pollution, sediment
generation and hence water pollution and quality
degradation is quite enormous and worth investigation.
The land use changes in a spatial manner
making the basin ideal for a temporal variation of
sediments yields along the river profi le and their
impacts on the water quality status. This paper
examines the results of study carried out within
the basins in the years 1998–2006. The method
of study involved water sampling and laboratory
analysis to reveal the trends in sediment load increases
downstream the investigated streams.
Soil samples were also investigated to determine
their relationship to soil erosion rates and sediment
fl uxes. The study attempts further to fi nd the
best sediment management strategies in reversing
their increasing trends and restoring water quality
within the basin
