Assessment Of Floodwater Harvesting Infrastructures In The Namibian Cuvelai-Etosha Basin

Abstract The Cuvelai-Etosha Basin lies in north-central Namibia and due to the prevailing climatic situation, the basin is dominated by strong seasonal and annual variations of either very dry conditions with drought or heavy flooding in certain years. A growing population in the Cuvelai-Etosha Basin has resulted in increased demand for water for daily use and agricultural activities. Floodwater Harvesting Infrastructures are considered to be a more effective way to solve those problems. Henc...

ABSTRACT Quality water should be colourless, tasteless, odourless and free from faecal contamination. This study investigates the physiochemical and microbiological characteristics of sachet packaged water vended in four local government areas of Ekiti State, Nigeria of contamination of commercially vended packaged water and their public health implications. The four Local Government Areas were Ado-Ekiti L.G.A, Ikere L.G.A, ljero L.G.A and Ikole Local Government Areas of Ekiti State. Five sac...

EFFECT OF DOMESTIC WASTEWATER DISCHARGE ON WELL WATER USE QUALITY IN IKOLE-EKITI, EKITI STATE, NIGERIA

 ABSTRACT The aim of the present study is to know the effect of wastewater (sewage) discharge on the quality water in Ikole-Ekiti, Ekiti State Nigeria. The community discharges wastewater which affect the water quality with most of the wastewater coming from domestic wastewater. Associated with the development of the area, the increase of pollutants into the surface water has been majorly from domestic activities. The study involved sampling of well water from four communities in Ikole LGA o...

QUALITY ASSESSMENT OF ABATTOIR EFFLUENT ON SURFACE WATER IN AKURE SOUTH, ONDO STATE, NIGERIA

ABSTRACT Water quality is very important in the environment, because life depends on this, it's very good to check the quality of water time to time to check the rate at which it is been degraded. The objective of this work is to determine the physiochemical and heavy metal parameter of abattoir effluent to surface water and compare the standard to WHO. Two empty bottles were used to collect sample from the surface water, GPS was used to get the geographical coordinate and samples were taken ...

ASSESSING THE QUALITY OF SURFACE WATER FOR IRRIGATION PURPOSE

ABSTRACT The study areas (Water works, Ureje and Kurundu) are situated in Ado Local Government Area of Ekiti State, and lies within latitude 7°45'N and 7°25'N and longitude 5°60'E and 6°00'E respectively. The study area also falls within the basement complex of south western Nigeria. The dominant lithologies include migmatities, granite gneisses, quartzites, charnockites and granites. Physical, chemical and bacteriological evaluation of surface water in the study areas were carried out to...

STATISTICAL ANALYSIS OF RAINFALL CHARACTERISTICS IN AKURE, ONDO STATE.

ABSTRACT This study examines the trends, onset, cessation and growing season of rainfall over Akure using data obtained from the archive of Nigerian Meteorological Agency (NIMET) Oshodi, Lagos, over the period of 1970-2005. Standardized Precipitation Index (SPI) was estimated from the available Rainfall records, Decadal analysis of Akure indicated 1991-2000as a wet decade, while 1981- 1990 was a dry decade. The onset and cessation dates were determined. The estimated parameters were subjecte...

GEOSPATIAL ASSESSMENTS OF HYDROLOGICAL IMPACTS OF FLOOD OCCURRENCES IN ADO-EKITI AND ENVIRONS

ABSTRACT Flood risk assessment is an important component of risk management. This study aims to generate a GIS-based flood risk map that can facilitate proper planning of mitigation measures against future floods occurrences. This study uses GIS technique and remotely sensed data to assess the extent of urbanization in land use, and vegetation changes in Ado-Ekiti metropolis between 1986 and 2017. Digital Elevation Models (DEM), settlement maps and satellite imageries to assess the susceptibi...

GEOSPATIAL ASSESSMENTS OF HYDROLOGICAL IMPACT OF FLOOD OCCURRENCES IN ADO-EKITI AND ENVIRONS

ABSTRACTDrought is one of the a resultant effect of climate change and it is the naturally occurring phenomenon that exists when precipitation has been significantly below normal recorded levels, causing serious hydrological imbalances that adversely affect land resource production systems. Unlike many other natural hazards, drought develops slowly, making it difficult to pinpoint the onset and termination of an event. The environmental impacts of hydrological drought are Reduced stream flow ...

APPLICATION OF THE STANDARDIZED PRECIPITATION EVAPOTRANSPIRATION INDEX (SPEI) IN BENIN-OWEN A RIVER BASIN, NIGERIA

 ABSTRACT Precipitation deficit and its daily, seasonal and annual oscillations are inherent characteristics of Nigeria's climate. Droughts are generally characterized by a prolonged and abnormal moisture deficiency. In drought studies it is important to characterize the start and end of a drought as well as its intensity, duration, frequency and magnitude. The objective of this study was to apply the Standardized Precipitation Evapotranspiration index (SPEI) for drought assessment in the Be...

ASSESSMENT OF POTENTIALLY TOXIC ELEMENTS IN HAND DUG WELLS AND BOREHOLE WATER IN IKOLE-EKITI AND ITS ENVIRONS, EKITI STATE, NIGERIA.

ABSTRACT Water is an important resource for almost all human activities like agriculture, industry, transportation, domestic uses and the proper functioning of the human body, The study examined the physiochemical properties and potentially toxic metals in hand-dug wells and boreholes in Ikole Ekiti and its Environs. Six functional hand-dug wells and six boreholes in the area were sampled and analyzed using standard procedures. Potential toxic metals were determined using Atomic Absorption S...

CHEMICAL COMPOSITION OF BOREHOLE WATER IN TWO LOCAL GOVERNMENT AREAS OF ONDO STATE WITH SPECIAL REFERENCE TO POTENTIAL TOXIC METALS

 ABSTRACT Many households are used to the construction of shallow wells, but the wells hardly provide adequate water supply in term of volume and quality throughout the year. As a result, government adopted the construction of boreholes as an alternative to pipe-borne water supply and as an immediate solution to water supply and quality problem. Groundwater (borehole water) samples were collected randomly from two (2) Local Government Areas: Akure south (Oda, Ijoka, Sebi, Kajola, Ijapo hous...

RAINFALL DISTRIBUTION AND THE LENGTH OF GROWING SEASON IN NORTHERN NIGERIA

 ABSTRACT This study examines the rainfall distribution and the length of the growing season in Northern Nigeria using the daily rainfall data from the selected stations Gasua, Kaduna, Kano, Katsina, Maiduguri, Potiskum, Sokoto, Yelwa, Zaria. The data were collected from the archives of the Nigerian Meteorological Services, Oshodi, Lagos. The length of the growing season was determined using the cumulative percentage mean rainfall method. The growing seasons in Gasau, Kaduna, Kano, Katsina, ...

METHODS OF ESTIMATION OF IONIC STRENGTH IN HAND DUG WELL WATER OF IKOLE-EKITI EKITI STATE NIGERIA

ABSTRACT The estimation of ionic strength and its activities in well water source within the vicinity of Ikole local government Ekiti state was conducted. A total of fifteen ( 15) water samples were collected from five locations (Al, A2, A3, Bl, B2, B3, Cl, C2, C3, DI, D2, D3, El, E2 and E3) from the study area. These samples were examined for major cations and major anions using Atomic Absorption Spectro-photometer (210 / 211 YGP (AAS)) and Technicon Auto analyzer AAII system respectively. F...
