Abstract: Fresh water is essential for the existence and development of any community. In Gongoni, Kilifi County, groundwater forms the primary source of fresh water. The presence of salt harvesting activities in the area and the concentration of pit latrines within their vicinity pose major pollution risks to these water sources. Salt harvesting ponds, which play a key role in concentrating sea water during the salt harvesting process, have a potential of affecting the quality of ground wat...
Abstract: The main objective of the study was to determine how river discharge and sediment yield in the basin is influenced by variations in rainfall and land use land cover change. The study was based on the analysis of hydrological and meteorological data archived by the Water Resources Authority (WRA) and the Kenya Meteorological Department (KMD), respectively. The river discharge, Total Suspended Sediment Concentration (TSSC) and sediment yield data was collected from established river ...
Abstract: Rainfall remains the crucial component of the weather elements for improving agricultural yield. Different models are used to explain the intra-seasonal features like water balance, Reddy model, Mann Kendal test, Markov Chain and Standard Precipitation Index. The water balance and Reddy models were used to analyze the variability and stability of onset, end and length of growing periods for common crops and soil conditions. The analysis of the annual rainfall was made by daily Prec...
ABSTRACT The study area is located in the Abakaliki formation of Asu-River group Lower Benue Trough. The area lies between latitude N060221 011to N060 281 011of the equator and longitude E0080 001 011 to E 0080 061 011of the Greenwich meridian. The study was carried out to ascertain the geology and the occurrence of groundwater in the area through detail geological field mappings geophysical investigation and pumping test. Field observations shows that the area is made up of two lithologic...
ABSTRACT In rural areas, water availability in the right quantity and quality is an important step towards achieving socio-economic development. Thus, the provision of sustainable water supply has been a central issue in Kenya with priority on low-income rural communities and underdeveloped areas with poor water resources. This has forced many rural communities to embrace community management model in rural water systems. However, despite continued large-scale investment by the government an...
ABSTRACT Various studies have shown that land use impacts on water quality are attributable to about 80 % of diseases in the developing world. The main objective of the study was to evaluate the effects of land use on water quality in River Malaget sub-catchment. The specific objectives were to: i) establish spring and streamflow water quality; ii) determine the water quality index of the selected sampling points and iii) evaluate the relationship between spring and streamflow water quality ...
ABSTRACT Access to quality water remains a key indicator of an improved social and economic life of any community. Due to an increasing human population, changes in land use activities and climate variability, Nyangores Basin in Kenya has been under pressure and for this reason, availability and access to quality and sufficient quantity of water has been adversely affected. Despite government plans to ensure all households access piped water; this has not been achieved as coverage is still v...
ABSTRACT Availability and accessibility of safe water is key to sustainable livelihoods in the world hence, poverty eradication and good health leading to agricultural and economic prosperity. Poor water availability and accessibility is a pressing problem in developing countries in Africa, therefore, understanding of water as a natural resource and human consumption commodity can help solve the problem and contribute to achievement of Millennium Development Goals (MDGs). Kenya is a water sc...
ABSTRACT The area of study occurs mainly within the Calabar Flank and part of the adjacent basement terrain of the Oban Massif. The latter is composed of mainly migmatitic gneisses, phyllites, amphibolites, granites, schists and granodiorites, while the major lithologies of the Calabar Flank include carbonates, shales, claystones and sandstones. This study aims at determining the quality and usability of the water, in addition to ascertaining the possible pollutants and ways to ameliorate the...
The economic importance of groundwater in the Greater Accra Region cannot be overemphasized, since supply from boreholes and wells continues to be the most dependable alternative sources of water for most rural and urban communities in the region. Three different consolidated hard rocks underlie the region making it difficult to produce volumes of groundwater for supplies. Demand for portable water has led to the drilling of large numbers of boreholes. This study statistically assesses t...
