Modelling Flooding Sites Around River Niger Area of Onitsha Town Nigeria Using Remote Sensing and GIS Application Dr Sylvanus Iro, Dr C.E Ezedike
International Journal of Scientific & Engineering Research Volume 11, Issue 2, February-2020 1027 ISSN 2229-5518 Title; Modelling Flooding sites around River Niger area of Onitsha town Nigeria using Remote Sensing and GIS Application Dr Sylvanus Iro, Dr C.E Ezedike Abstract; Increasing frequency and severity of flooding have caused tremendous damage in Onitsha area of Nigeria, requiring more efficient and effective way to reduce the risk and damage people face. In this study, the Digital Elevation Model (DEM) of the study area was used in consideration of terrain's influence on flooding of the town. The Compound Topographic Index (CTI) of the area was calculated to extract areas that represent wetness, which shows areas liable to flooding. The DEM was further queried to identify the part of the town that will be flooded whenever River Niger rises to 5 metres above the current level. The result shows that of the 1226610m2 of the study area, flooding will inundate area approximately to 2400m2, representing 0.47% of the DEM cells of the total study area. The slope map indegrees identified areas with more than 890 to be safe from flood inundation when the river rises and areas less than 890 to be areas liable to flooding. The analysis of this model shows that the proposed model can be a valuable tool that will guide city planners to avoid areas that are liable to flooding being used as residential or commercial purposes and for minimising damages from flooding. Keywords: Flooding, River Niger, Remote Sensing, Geographic Information System and Digital Elevation Model. -

URBAN SPRAWL, PATTERN AND MEASUREMENT IN LOKOJA, NIGERIA URBAN SPRAWL, PATTERN AND MEASUREMENT IN LOKOJA, NIGERIA Michael Oloyede ALABI Department of Geography and Planning, Kogi State University P.M. B. 1008, Anyigba, Nigeria ement [email protected] Abstract Lokoja have been experiencing a large influx of population from its surrounding regions, which had led to rapid growth and expansion that had left profound changes on the landscape in terms of land use and land cover. This study uses the GIS techniques and the application of Shannon’s entropy theory to measure the behavior of sprawl which is based on the notion that landscape entropy or disorganization increases with sprawl, analysis was carried out based on the integration of remote sensing and GIS, the measurement of entropy is devised based on the town location factors, distance from roads, to reveal and capture spatial patterns of urban sprawl. Then Entropy value for each zone revealed a high value, especially areas outside the core city area; like Felele, with the entropy of 0.3, Adankolo, 0.2 and Lokongoma, 0.2. These areas are evenly dispersed settlement, as one move away from the city core. Study shows a correlation of population densities and entropy values of 1987 and 2007, for areas like Felele ,Adankolo, and Lokongoma , which is indicative of spread over space , an evidence of sprawl. But as we go down the table the entropy values seem to tend towards zero. -

Received 9 June, 2020; Accepted 4 September, 2020 This study applied Log-Pearson Type III probability distribution to model time series annual peak flow records of River Niger recorded at Lokoja gauging station. This was necessitated by the need to provide reliable data for safe and economic hydrologic design for security of lives and property at downstream of river Niger basin. Though several methods have been adopted in the study area for flood mitigation, however, it has become apparent that these measures are inadequate and no attempt has been made to apply statistical approach for provision of sustainable solution. Though flood cannot be prevented but the impact can be reduced by applying adequate counter measures. Therefore, this study shows the result of flood frequency analysis based on annual peak flow measurement covering a period of 18 years (1995-2012) carried by National Inland Water Ways (NIWA) at Lokoja gauge station. The probability distribution function was applied to return periods (T) of 2, 5, 10, 25, 50, 100 and 200 years. -

Sunday P. Ejaro* and Umar Abdullahi Department of Geography and Environmental Management, University of Abuja, Abuja, Nigeria. *E-mail of corresponding author: [email protected] Abstract This study examines the spatial and temporal changes in land use and land cover in Suleja Local Government Area (LGA) of Niger State between 1987 and 2012, as well as, the rate of change, factors responsible and suggests measures on how to check the trend in order to maintain sustainable development. The study utilised ILWIS 3.3 software for the processing and classification of the tri-date (1987, 2001, and 2012) satellite images. The method for the analyses of the land use and land cover change is the Post-classification Comparison Method (PCM). Land use and land cover change data obtained from each period is presented in colour composite maps and tables. The results obtained show that the proportion of area covered by built up land, farm land and bare soil is on the increase, whilst there is decline in vegetation. Built up land increased from 7.0 km 2 (or 5.2%) in 1987 to 17.9 km 2 (or 12.5%) in 2012, farmland from 50.1 km 2 (or 36.7%) to 63.0 km 2 (or 46.2%) and a decline in vegetation from 68.7 km 2 (or 50.4%) in 1987 to 43.1 km 2 (or 31.6%) in 2012. -

Death and the Textile Industry in Nigeria
Death and the Textile Industry in Nigeria Elisha P. Renne First published in 2021 ISBN: 978-0-367-46552-0 (hbk) ISBN: 978-1-003-05813-7 (ebk) Conclusion Death, deindustrialization, and time (CC BY-NC-ND 4.0) This OA chapter is funded by Elisha P. Renne. Conclusion Death, deindustrialization, and time “We felt that society was dragging anchor and in danger of going adrift. Whether it would drift nobody could say, but all feared the rocks.” Edward Bellamy, Looking Backward, 2000–1887 This volume focuses on the consequences of deindustrialization on the lives of former factory workers at the Kaduna Textile Ltd (KTL) mill in the Kakuri area of Kaduna and the “work of the dead” in ameliorating these changes. As such it addresses the question, “How is deindustrialization experienced dif- ferently by people in varied places, times, and circumstances?” (Cowie and Heathcott 2003: 5). As many of the workers at KTL came from rural towns and villages to the south of the city of Kaduna, their experience reflects many changes: from rural to urban living, from agricultural to industrial labor, and to new conceptions of time and work. Their experience has been complicated by the failure of the government to pay negotiated remittances owed to KTL workers following the company’s closure, which was not the case for most other Kaduna textile mills. Consequently, KTL workers, as members of the National Union of Textile Garment and Tailoring Workers of Nigeria, sought to pressure the company to release these funds in order to ease the difficulties of finding alternative sources of income and of paying for food and health care as well as supporting their families. -

Analysis of Nigerian Hydrometeorological Data
Nigerian Journal of Technology, Vol. 22, No. 1, March 2003 Dike & Nwachukwu 29 ANALYSIS OF NIGERIAN HYDROMETEOROLOGICAL DATA By Dike, B. U. and Nwachukwu, B.A. Department of Civil Engineering Federal University of Technology, Owerri ABSTRACT Rainfall and runoff like most hydrologic events are governed by the laws of chance; hence, their predictions cannot be done in absolute terms. Since there is no universally accepted method for determining the likelihood of a certain magnitude of rainfall or runoff, common probabilistic models were used in this research to predict the magnitude and frequency of their occurrence. Missing records were determined by the mass curve analysis for rainfall and regression analysis for runoff involving runoff data at neighbouring site. Tests on time homogeneity, showed that the annual rainfall records at Port Harcourt, Enugu and Lokoja were stationary and random, the annual runoff records of River Niger at Onitsha, Lokoja and Baro were non-stationary, showing a decreasing trend of mean annual runoff. Various models were tested for suitability in predictions of annual rainfall at Port Harcourt, Enugu and Lokoja, also for annual runoff of River Niger at Onitsha, Lokoja and Baro. The mean annual rainfall was found to diminish from the coast to inland with values' of 2, 400, 1, 700, and 1,200mm for Port Harcourt, Enugu and Lokoja respectively. The mean annual runoff for River Niger at Onitsha, Lokoja and Baro were 117, 000, 169, 300, and 60, 525 Mm3 respectively. The application of the models showed that the lognormal distribution should be adopted for predictions of annual rainfall at Port Harcourt and Lokoja and annual runoff of River Niger at Onitsha and Lokoja, The normal distribution should be adopted for predictions of annual rainfall at Enugu and annual runoff of River Niger at Baro.
