dc.description.abstract | The purpose of this study was an evaluation of
hydrological aspects within the rivers Rwamuthambi and Ragati
sub-catchments, relating to certain discharge and suspended
sediment load characteristics. This was with respect to annual
variability of discharge; existence or absence of persistence
in the discharge series; peak and low flow frequencies; and the
magnitudes and variability of suspended sediment loads.
The Ragati and Rwamuthambi sub-catchments of the Upper
Tana cover an area approximately 448.2 Km2. The sub-catchments
are drained by rivers Ragati and Rwamuthambi originating from
the Mt. Kenya forest. They cover a region that fall within
parts of Kirinyaga and Nyeri districts of Central Province,
Kenya.
The methodology adopted in this study involved a
preliminary data collection exercise followed by qualitative
and quantitative analysis. Data on sediment load was collected
through water sampling followed by laboratory analysis while
river discharge data was got through flow gauging and
supplemented with secondary data. The statistical methods of
data analysis employed included Analysis of variance (ANOVA),
Time Series Analysis,Frequency Analysis and the Student's ttest.
Fro~disCharge data analysis, it was observed that the
reliabiliti of established discharge-rating curves in defining
the discharge-gauge height relationships diminished with time | en |
