KILEA, RICHARD MUENDO
Geothermal energy is thermal energy from the subsurface of the earth. The heat is extracted in
form of steam, and is tapped in the surface at very high pressures. Geothermal energy is renewable,
carbon free and free form of energy that provides a continuous and uninterrupted supply of power
and heat. Utilization of Geothermal energy began in the early 19
th
century and as civilization
advanced, this form of energy became most preferred and thus there is need to increase its capacity
because it is not fully utilized. Kenya is endowed with this form of energy along the rift valley due
to the recent quaternary volcanoes. Currently Kenya has an installed capacity of over 900 MWe,
however the geothermal capacity in the country is more than 7,000 MWe. Only 5 of the 14
geothermal prospects have been developed while the rest are in different stages of exploration.
This project highlights the geothermal portfolio capacity in Kenya and ranks the remaining 9
geothermal fields in their order of development. These fields include; Emuruangogolak, Suswa,
Longonot, Arus Bogoria, Lake Baringo, Silali, Namarunu and Barrier geothermal field. To achieve
this ranking, surface geoscientific data was generously given by various sources such as the main
two industrial geothermal players (KenGen and GDC) and the Ministry of Energy. The data was
reviewed and integrated to come up with a basis for the classification and ranking. Using this data,
the project developed detailed raw conceptual models of each geothermal field and power potential
estimates using power density calculations. Power density method of geothermal power
calculation gives first order estimates of the geothermal filed expressed in terms of MW/km².
Results of this work has ranked the fields as follows: Taking the resource capacity estimates,
geological, hydrogeological, and fluid chemistry criteria into consideration and some socio-
economic factors, the geothermal prospects are ranked as follows: Suswa, Longonot, Silali,
Emuruangogolak, Korosi, Barrier, Arus Bogoria, Lake Baringo and Namarunu; Suswa being the
most viable.

MAINA, ERASTUS
This project details the implementation of a Geographical Information system in water service provider companies to increase efficiency in the management and maintenance of the water utility network by providing information that can be used by the technical guys in their daily routines and carrying out simple tasks like repairing and locating ineffective part of the network. The need arise as the water network in Nanyuki have not been mapped they still rely on the memory of their staffs in managing their assets and with the amount of information those water service providers deal with need a good information system to handle it. This is to ensure that good monitoring of water network and improvement of supply which has been a challenge has been achieved. Embracing the GIS technology is the solution to most of the problems faced by utility companies from data collection to field-workforce.
The objective of the project is to generate a desktop geographical Information system that can be applicable by any water service provider (WSP) day-in day-out. The methodology adopted in this project is that of a stand-alone geographic information system that involved establishment of a local geodatabase and mapping the water utility network of a pilot area that is followed by creation of geometric network dataset and various analysis. The methodology adopted resulted to mapping of most of the water utility network integrated with the customers’ information which would face-out the reliance of staffs’ memory who might not stick in the company for long.
The project provided information that could be used by maintenance crew during repair like the shortest route maps, upstream and downstream analysis map to help determine which valve to close during repair and from which main valve does a certain customer benefit from, and map showing critical components within the network just to name a few.

CASE STUDY OF KAKUMA REFUGEE CAMP, TURKANA COUNTYEKOMWA, EVERLYNE MORITAhttp://repository.dkut.ac.ke:8080/xmlui/handle/123456789/12322020-06-10T06:36:32Z2020-01-01T00:00:00ZGIS IN ASSESSMENT OF WATER POINT SOURCES. CASE STUDY OF KAKUMA REFUGEE CAMP, TURKANA COUNTY
EKOMWA, EVERLYNE MORITA
Water is a very important natural resource, with a variety of applications domestically and industrially and is thus very essential for the survival of mankind, wildlife and vegetation. Unfortunately, only about 0.8% of the available water on the earth’s surface is usable, that is, is fresh and exists in a non-frozen nature. Kakuma exists in a semi-arid region with virtually no vegetative cover, and thus there exist very few surface water sources in the region.
The objective of the research was to map out the existing water points and to identify new location for water points using spatial model.Geospatial technology employed was data collection,capturing by scanning,georeferenced,projection,and data overlay. The data collected was analysed using spatial model.
The result obtained shows that there is inadequate water sources due to high increasing population in the camp

Patrick, Wachira
Land is a major factor of production in Kenya, it has major influence in economic, social, environmental and political activities.
This research will purposely aim at investigating the gaps from land registration process where documents for registration does not guarantee 100 percent security of land tenure. The output of this research may aid in the development of a better land registration procedure for Thika municipality and also similarly affected municipalities. In Africa and other developing countries, land registration systems are struggling and access to the registered documents is limited. In Kenya most of the land is not formally registered and it denies citizens enjoying the full benefits of an efficient land registration.
Thika municipality as the specific area of study was chosen because of its dynamism, rate of growth and its proximity to Nairobi city. There exists three types of registration systems to acquire rights to land namely; Registration of Titles Act (RTA), Registered land Act (RLA) and General boundary. Which are operated and managed using manual systems despite the increased availability of the current digital Land Information Systems.
A case study method will be used where a prototype cadastral database was developed together with a mobile application proposing a quick, efficient and transparent method of data capture, registration and management. This was after the various and persistent challenges observed and are negatively affecting access, sharing and retrieval of geospatial data. The proposed system demonstrated that integration of geospatial information within a GIS platform may be better than the analogue system in cadastre data display, retrieval and management. Its results are predictable and interoperability is high. The shift towards embracing the new technology by using an LIS suggests that manual systems in land registration should be abolished since individual rights to security of tenure are embedded within a wider social obligation.
