This paper discusses the results of a study carried out in 2003 on the water quality of Nairobi River on the basis of pollution parameters and water quality index. The study aimed at establishing whether the water meets the surface water quality criteria for water supply. The area of study in Nairobi River was within its entry and exit of Nairobi province. It was observed that human activities along the river with visible encroachment to the banks, contribute to the heavy level of pollution of the river. This is the section that industrial discharges and municipal sewerage are discharged into the river. The study was carried out through field surveys and laboratory tests on samples taken from the river. The results obtained from laboratory tests were analysed and compared to the established surface water quality criteria by A.S.C.E, W.H.O, Natural watercourses Standards of Kenya and classification of rivers by Royal Commission on Sewage Disposal. Human activities along the river course have severely impacted on the River water quality. The study area had average pH of 7.04; the average turbidity was 41.5N.T.U, the average suspended solids in the section was 116.43 mg/l, the average dissolved oxygen was 4.32mg/l. the average BOD was 182.5mg/l. The average COD for the reach studied was 49.5mg/l. The river was therefore classified as bad according to Klein 1966. The study concluded that the Nairobi River within Nairobi province was badly polluted as indicated by the water quality index analysis. The WQI gives a value of 49.27, fall between the numerical ranges of the classification of bad (26-50).

Dulo, Njunguna. "Modelling Change in Development on Urban Runoff.". In: National Hydrological Society Conference. UNESCO - HSK; 2012. Abstract

Cities around the world are currently facing considerable pressure to cope with infrastructure provision amidst rapid urban development and economic growth. Kenya is also facing an
increasing growth of informal settlements in her urban centres. As rapid urbanization takes its toll, so has the development and growth of slums. More than 34% of Kenya‟s total population lives in urban areas and of this, more than 71% is confined in informal settlements (UN-Habitat, 2009).
This paper presents the result of study to assess the effects of the change in land use in two sub-catchments, in an urban area close to the Nairobi Central Business District (NCBD). The paper compares the change in land use of two regions in Nairobi, Kenya that are slowly changing due to the fast growing population and economy, on urban runoff.
