    • Development of a streamflow model for rural catchments in Kenya. 

      Gichuki, F. N; Mungai, D. N; Gachene, C. K. K; Thomas, D. B. (University of Nairobi,college of agriculture and veterinary sciences,, 1993)
      A stream flow model was developed for use in rural catchments in Kenya. In the model the physical environment was divided into three zones: the unsaturated zone (consists of multiple hydrological response units defined by ...
    • Erosion and sedimentation problems in the arid and semi-arid lands of Kenya. 

      Denga, F. O; Ongwenyi, G. S; Kitheka, J. U.; Gichuki, F. N; Mungai, D. N; Gachene, C. K. K; Thomas, D. B. (University of Nairobi,college of agriculture and veterinary sciences,, 1993)
      This paper examine past and present trends in the development of Kenyan water resources, and the status of Kenya's arid and semi-arid lands. It considers the parameters linked with soil erosion and sedimentation processes ...
    • Land degradation in east Africa. 

      Stahl, M; Gichuki, F. N; Mungai, D. N; Gachene, C. K. K; Thomas, D. B (1993)
      This paper reviews the history and present crisis state of land degradation in the highlands of east Africa, which contain the most productive agricultural areas of Kenya, Uganda, Tanzania and Ethiopia. The main focus is ...
    • Riverbank protection and food security. 

      Gichuki, F. N; Mungai, D. N; Gachene, C. K. K; Thomas, D. B. (University of Nairobi,Department of soil science,, 2000)
      This paper reflects on the role of root crops (cocoyam, Colocasia esculenta or C. antiquorum) as a case study in riverbank protection and food security in Kenya. Field performance, water erosion control, ecologically ...
    • Sediment sources to Masinga dam 

      Gichuki, F. N; Mungai, D. N; Gachene, C. K. K; Thomas, D. B (1993)
      Preliminary findings on the effects of land use in the Masinga Dam catchment, Kenya, on the storage capacity of the reservoir are presented. Remote sensing and GIS techniques, supplemented with ground reports, were used ...
    • Some conceptions about sediment rating equations. 

      Gichuki, F. N; Mungai, D. N; Gachene, C. K. K; Thomas, D. B. (University of Nairobi,Department of soil science,, 2000)
      This paper examines the anomalies in the sedimentation rating equations in terms of existing notions of statistical analysis and concludes that c=aqb is the preferred relationship. The method of estimating parameters a and ...
