Geologists FOREWORD Previous to the undertaking of modern geological surveys the Naivasha area, in the south-central part of Kenya Rift Valley, was probably the best known part of the Colony from the geological point of view. This resulted partly from ease of access, as from the earliest days the area was crossed by commonly used routes of com­ munication, and partly from the presence of lakes, which in Pleistocene times were much larger and made the country an ideal habitat for Prehistoric Man and animals that have left their traces behind them in the beds that were then deposited.

Many thanks to KMFRI Naivasha technical team for assisting with logistics and sampling, and to the entire KMFRI Naivasha staff for their support. iv Abstract This study presents the first documentation of the status of the River Malewa fishery, a major river draining into Lake Naivasha and, to relate the status of the current commercial fishery to information on potential yields so as to identify whether or not there is a scope for better management and utilization of the resource (River Malewa fishery).Six sampling sites were selected from the upper catchment area of the Malewa river system to the lower catchment as it drains into Lake Naivasha.An integrated assessment of water quality to all sites, including the collection of fish communities, physical habitat and chemical information to assess river Malewa conditions was conducted.

Journal of Spatial Hydrology Vol.7, No.1, Spring 2007 Hydrodynamics of topographically closed lakes in the Ethio-Kenyan Rift: The case of lakes Awassa and Naivasha Tenalem Ayenew1*, Robert Becht2, Arno van Lieshout2, Yemane Gebreegziabher3, Dagnachew Legesse1, Japheth Onyando4 Abstract The hydrodynamics and the long-term water balance of two topographically closed crater lakes is presented in a comparative manner using a spread-sheet hydrological model. The main objective of the work is to study the role of groundwater and the effect of water abstraction from lakes Awassa and Naivasha. The rationale of selection of the two lakes separated by thousands of kilometers is the striking similarity of their hydrogeological and geomorphological setting and future intended water uses for large-scale abstraction from the lakes and feeder rivers. The net groundwater outflow from Lake Awassa and the effect of water abstraction from Lake Naivasha under different scenarios were calculated based upon the average monthly hydrometeorological data of rainfall, evaporation and river inflows.

Tel. +49-331-977-5810, Fax +49-331-977-5700, E-mail [email protected] The development of the Cenozoic East African Rift System (EARS) profoundly re-shaped the landscape and significantly increased the amplitude of short-term environmental response to climate variation. In particular, the development of amplifier lakes in rift basins after three million years ago significantly contributed to the exceptional sensitivity of East Africa to climate change compared to elsewhere on the African continent. These amplifier lakes respond rapidly to moderate, precessional- forced climate shifts, and as they so apply dramatic environmental pressure to the biosphere. Rift basins, when either extremely dry or lake-filled, form important barriers for migration, mixing and competition of different populations

  • Hydrologic Analysis of Malewa Watershed As a Basis for Implementing Payment for Environmental Services (Pes)
    HYDROLOGIC ANALYSIS OF MALEWA WATERSHED AS A BASIS FOR IMPLEMENTING PAYMENT FOR ENVIRONMENTAL SERVICES (PES) L. P. Ogweno1, J. M. Gathenya2, and P. G. Home3 1 Kenya Industrial Research and Development Institute, Nairobi, Kenya 2,3Department of Biomechanical and Environmental Engineering, Jomo Kenyatta University of Agriculture and Technology, Nairobi, Kenya E-mail: [email protected] Abstract This paper investigates the hydrological effects of specific land use changes in Malewa catchment through the application of the Soil and Water Assessment Tool (SWAT) as a basis for implementing PES on a daily time step. The model's calibration efficiency is verified by comparing the simulated and observed discharge time series at the outlet of the watershed, where long series of hydrometrical data exist. The model is used to simulate the main components of the hydrologic cycle, in order to study the effects of land use changes. The model was calibrated and validated for the prediction of flow. Extensive continuous flow data over 10-year period from three locations within the basin were used for model calibration and validation. Sensitive model parameters were adjusted within their feasible ranges during calibration to minimize model prediction errors for daily and monthly flows. Water quality parameters (sediment, nitrogen and phosphorous loadings) were not available hence were not calibrated but the model default values were used after calibrating the flow data. At the main gauging station 2GB01; monthly calibration resulted in model prediction average flow within 19% of the measured average flow while the monthly Nash-Sutcliffe (ENS) measure was 0.58. Monthly validation results for 2GC05 and 2GB07 showed the model predicted average flow within 20% of the measured average flow with ENS of 0.58 and 0.61 respectively.

Geologist |5*9> FOREWORD This report covers nearly 2,500 square miles of the central sector of the Great Rift Valley and its eastern shoulders, an area of great diversity of topography and rock-types in which are to be found many vital clues as to the origin and age of the rift. Dr. McCall's pains­ taking work in describing and unravelling all the evidence contained in this region therefore makes up a volume which is somewhat larger than the normal reports of the Geological Survey, but will nevertheless be of absorbing interest to geologists and geomorphologists.
