(Department of Geology, University of Nairobi, 1994)Thirty three surface water samples, thirty one groundwater samples and nine samples of sewage and industrial effluents were collected and analysed for various parameters mainly for Biological Oxygen Demand (BOD), Chemical ... -
Impacts of rainfall on aircraft operations at Julius Nyerere international airport and Shinyanga airport, Tanzania.
(Department of Meteorology University of Nairobi, 2009)Although air transportation seems to be the best way of travels in Tanzania sometimes it became unsafely and unreliable due to the different factors including bad weather such as heavy rains. Bad weather may lead to ... -
Numerical simulation of the influence of the large-scale Monsoon flow on the diurnal weather patterns over Kenya
(Department of Meteorology University of Nairobi, 1992)The influence of the large-scale monsoonal wind systems on the diurnal weather patterns over Kenya was investigated in this study using a three-dimensional limited-area model known as the Regional Atmospheric Modeling ... -
Hydrogeology of lake nakuru drainage basin using electrical resistivity survey.
(Department of Geography, University of Nairobi, 2000)The Lake Nakuru Drainage Basin is underlain by volcanic and volcano-sedimentary rocks of PliocenePleistocene-Recent Periods. These rock types are common water bearing formations, especially the weathered,fractured or ... -
Influence of fog on aircraft delays at Jomo Kenyatta international airport, Nairobi, Kenya
(Department of Meteorology University of Nairobi, 2006)In this study, the influence of fog on aircraft delays at JKIA for the period 2000 to 2005 is considered. Delays are defined in terms of the difference between the actual flight time and that projected by the air traffic ... -
The simulated impact of deforestation on the changes in the East African climate: a GCM study
(Department of Meteorology University of Nairobi, 2006)This study investigates the possible impact of deforestation on the climate of Eastern Africa. The study area is located between approximately longitudes 25 °E to 50 °E and latitudes 20 "N to 10 "S. The data used in the ... -
Structural analysis of the drainage basin of kenyan rift Valley lakes within the aberdare detachment, using Satellite data, gis and field observations
(Department of Geology, University ofNairobi,, 1999)In addressing the problem of lake-level changes in the drainage basin of the Kenyan Rift Valley lakes (Bogoria, Nakuru, Elmenteita, Naivasha) of the Aberdare Detachment System, a study of the watershed of the basin is ... -
Lithostratigraphic analysis and palaeoenvironmental Interpretation of the late tertiary and quaternary sediments of The Nakuru, Elmentaita and Naivasha basins.
(Department of Geology, University of Nairobi, 1993)The objective of this thesis is to provide a better understanding and correlation of the lacustrine palaeoenvironments of the late Tertiary and Quaternary rift sediments within the basins of Lakes Nakuru, Elmentaita ... -
An investigation of the effects of urbanization on the climate of Maseru, Lesotho
(Department of Meteorology University of Nairobi, 2006)The influence of urbanization on the local climate has been identified in various parts of the world by a careful study of trends in meteorological parameters over a period of time. Although these effects may not be ... -
Numerical simulation of the influence of mesoscale forcing on the large-scale flow and weather over Ethiopia
(Department of Meteorology University of Nairobi, 2003)The influence of large-scale monsoonal winds and thermally-induced mesoscale circulations on the diurnal weather pattern over Ethiopia was investigated in this study using a three-dimensional limited area model known as ... -
The effects of contour hedgerows (alleycropping) on microclimate, soil and water conservation and competition on sloping lands for sustainable land use in Machakos district, Kenya
(Faculty of Science, University of Nairobi, 1999)The research was conducted in a semi-arid land of Kenya prone to land degradation when open for rainfed agriculture. Insufficient water and soil erosion limit plant growth and development. The area has erratic rainfall ... -
Transport and dispersion patterns of aerosols over the east African region
(Department of Meteorology University of Nairobi, 2010)This study used aerosol optical depth (AOD) from satellite based Moderate Resolution Imaging Spectroradiometer (MODIS) observations at 550nm in 1° X 1° grid resolution to investigate the transport and dispersion patterns ... -
A numerical study of the effects of the roughness length on the meso-scale flow patterns over Kenya
(Department of Meteorology at the university of Nairobi,, 1992)A three-dimensional numerical model was used in this study to examine the effects of changes in the surface roughness length on the meso-scale flow patterns over Kenya. Three experiments were performed. The first ... -
