Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: K Schachtschneider K WinterThe study involves the analysis of groundwater around Bass Lake, part of a fragile black water lake system situated along a narrow coastal plain in the southern Cape, in order to establish the quality of the water and to identify... -
Oualidia lagoon, Morocco: an estuary without a river
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: K Hilmi VG Koutitonsky A Orbi JI Lakhdar M ChagdaliThis study describes some physical oceanography features of an estuary maintained by fresh groundwater inflow. The mesoscale variability of currents, temperature and salinity are documented from moored current meter observations of 12 days duration at three stations. Current speeds exceeded... -

Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: Julius Kipkemboi AnneA van Dam Patrick DennyThe potential effect on ecosystem integrity of the use of natural wetlands for seasonal wetland fishponds ('fingerponds'), integrated with vegetable production for livelihood demands, was evaluated using experimental sites at Lake Victoria, Kenya. Soluble reactive phosphorous and total phosphorus, ammonium,... -
Heavy metals in the water and sediments of Oued Es-Souk, Algeria, a river receiving acid effluents from an abandoned mine
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: Chahrazed BoukhalfaThe Sidi Kamber Mine, abandoned since 1976, is still a source of acidic drainage entering the Oued Es-Souk River. An investigation of the rate of pollution of the Oued Es-Souk and the variation of its water quality showed that the... -
Impact of rainfall variability on groundwater levels in Ruiru municipality, Kenya
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: R.M. Nyakundi --- Department of Civil, Construction and Environmental Engineering, Kenya M. Makokha --- Department of Water Engineering and Technology, Kenya J.K. Mwangi --- Department of Civil, Construction and Environmental Engineering, Kenya C. Obiero --- Department of Land Resource Planning and Management, KenyaGroundwater accounts for the largest fresh water resources in the world. However, there has been limited exploitation of this vital resource in many areas. Where groundwater resources have been utilised, they have been over-exploited, polluted, wasted and mismanaged. In Ruiru... -
The annual pattern of sap flow in two Eucalyptus species established in the vicinity of gold-mine tailings dams in central South Africa
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Peter Dye --- Ecological Engineering and Phytotechnology Programme, Restoration and Conservation Biology Research Group, School of Animal, Plant and Environmental Sciences, South Africa Alistair Clulow --- Agrometeorology, South Africa Eric Prinsloo --- CSIR, Built Environment, South Africa Vivek Naiken --- CSIR, Natural Resources and the Environment, c/o Agrometeorology, South Africa Isabel Weiersbye --- Ecological Engineering and Phytotechnology Programme, Restoration and Conservation Biology Research Group, School of Animal, Plant and Environmental Sciences, South AfricaSeveral hundred mine tailings dams occur in the Witwatersrand Basin Goldfields in central South Africa. Seepage of acid mine drainage (AMD) from these unlined structures is widespread, and a variety of contaminants is released into soil and groundwater. The ‘Mine... -

Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Peter K. Mbaka --- Department of Civil, Construction and Environmental Engineering, Kenya John K. Mwangi --- Department of Civil, Construction and Environmental Engineering, Kenya Clement K. Kiptum --- Department of Civil and Structural Engineering, KenyaA supply of potable water is important for the sustenance of a healthy population. This study was conducted in the Keiyo Highlands, Elgeyo Marakwet County, in Kenya. The aim was to assess seasonal variation in physico-chemical and microbiological water quality... -
Assessment of vulnerability to groundwater pollution in Department of Odienné (North-West Côte d’Ivoire)
