Article Title: Estimating Water Table Elevations by Spatial Interpolation: A Case Study of Kamariny Division, Keiyo North District, Kenya
by Catherine Chebet

Abstract:
Water scarcity is a serious issue in Keiyo District and Kenya in general. Indeed Kenya has been classified as a water-scarce country. The water crisis in Kenya is disrupting social and economic activities throughout the country. As stipulated in the Vision 2030, the economic and social developments anticipated will require more high quality water supplies than at the moment. To be able to achieve this, there is need to conserve water sources and find new ways of harvesting and using rain and underground water. The Vision 2030 for water and sanitation is to ensure that improved water and sanitation are available and accessible to all. The surface water resources of the study area are meagre and the entire region is principally dependent on groundwater for its water needs. The study therefore focused on the exploration of ground water in Kamariny Division of Keiyo District using the latest techniques in Geographic Information Systems (GIS) and particularly spatial interpolation. The main aim of the study was to estimate water table elevations in the Division. The results of the study will assist the local people in estimating the depth of the water table at any point in the area and make the right decisions in terms of choosing the best site for their wells and also estimating the cost of digging the wells in advance. Scholars and general readers can adopt the same methodology in estimating water table elevations in other areas in Kenya.

Keywords: ground water, spatial interpolation, geographic information systems, water table.
