Présentation
The area of the study is located in the central part of the Rift Valley of Kenya. The objective of this study was to assess the behaviour of the groundwater flow system of the Nakuru-Elmenteita basin and to determine if lakes Elmenteita and Nakuru are hydraulically connected. This was approached mainly by using the study of hydrochemistry, stable isotopes and groundwater modelling. The groundwater flow direction in the study area is towards the lakes from the western and eastern escarpments. Stable isotope data from a well north west of Lake Nakuru also shows that there is about 29% Lake Elmenteita water in the mixture which implies the flow of groundwater from Lake Elmenteita towards Lake Nakuru. Stable isotope sample taken from Elmenteita fresh spring also shows 31.4% Lake Naivasha water which strengthens the conclusion given by previous studies on the contribution of Lake Naivasha water towards Lake Elmenteita. Hydrochemical analysis results, as well, show that groundwater flow is towards the lake from the eastern and western part of the escarpments. The model is not properly calibrated due to shortage of time and lack of data. But the preliminary calibration out put can be the basis for proper calibration
