Analysis Of Land Use Changes And Its Hydrological Implication On River Niger, Lokoja, Nigeria, O O. Ifatmehin Phd, P A. Essoka Phd, A Ahmed Dec 2012

Analysis Of Land Use Changes And Its Hydrological Implication On River Niger, Lokoja, Nigeria, O O. Ifatmehin Phd, P A. Essoka Phd, A Ahmed

Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria

This study evaluates the impact of urbanization on Meme river catchment of 667,560.5Km2 area in the Lokoja urbanizing area of Kogi State. The emphasis was to examine the rate of urbanization, changes in land-use, and changes in meme river channel. Land-sat satellite imageries of 1987, 2001, 2006 and 2011 were processed to examine how land use change processes affects rate of urbanization and impacted on the stream. Hydrological map of Meme River was digitized using ARCGIS 9 software to extract the precise study area. It was discovered from multiple regression analysis that light vegetation (.92), built up area (.81), rock …


Spatial Discrepancies Between Nhdplus And Lidar-Derived Stream Networks, Nicole Marie Samu May 2012

Spatial Discrepancies Between Nhdplus And Lidar-Derived Stream Networks, Nicole Marie Samu

Masters Theses

Many organizations demand that current water resource issues necessitate improved stream network mapping for more accurate and reliable watershed analysis and modeling results, which can ultimately enable better management and policy decisions. Stream network data from the National Hydrography Dataset Plus (NHDPlus) and derived from Light Detection and Ranging (LIDAR) are each widely accepted to be of superior quality compared to many other conventional datasets. Each dataset indicates potential to improve a wide range of water resource applications; NHDPlus for its high spatial accuracy and functionality, and LIDAR-derived networks for their high resolutions. NHDPlus is publicly available and widely used; …


Emerging Law Addressing Climate Change And Water, Prof. Elizabeth Burleson Jan 2010

Emerging Law Addressing Climate Change And Water, Prof. Elizabeth Burleson

Prof. Elizabeth Burleson

The World Economic Forum recognizes that while restrictions on energy affect water systems and vice versa, energy and water policy are rarely coordinated. The International Panel on Climate Change predicts that wet places will become wetter and dry places will become dryer. Transboundary water, energy and climate coordination can occur through international consensus building.


Surface Mining And Reclamation Effects On Flood Response Of Watersheds In The Central Appalachian Plateau Region, Todd R. Lookingbill, Joseph R. Ferrari, B. Mccormick, P. A. Townsend, K. N. Eshleman Jan 2009

Surface Mining And Reclamation Effects On Flood Response Of Watersheds In The Central Appalachian Plateau Region, Todd R. Lookingbill, Joseph R. Ferrari, B. Mccormick, P. A. Townsend, K. N. Eshleman

Geography and the Environment Faculty Publications

Surface mining of coal and subsequent reclamation represent the dominant land use change in the central Appalachian Plateau (CAP) region of the United States. Hydrologic impacts of surface mining have been studied at the plot scale, but effects at broader scales have not been explored adequately. Broad-scale classification of reclaimed sites is difficult because standing vegetation makes them nearly indistinguishable from alternate land uses. We used a land cover data set that accurately maps surface mines for a 187-km2 watershed within the CAP. These land cover data, as well as plot-level data from within the watershed, are used with HSPF …


Applicability Of Satellite Remote Sensing And Gis Techniques And Ground Data In Watershed Planning: The Case Of Kubili, Nigeria, Olarewaju Oluseyi Ifatimehin Aug 2007

Applicability Of Satellite Remote Sensing And Gis Techniques And Ground Data In Watershed Planning: The Case Of Kubili, Nigeria, Olarewaju Oluseyi Ifatimehin

Watershed land and hydrology are resources that are very important in agricultural development. Adequate and proper land use planning and management of these resources is of ultimate importance in sustainable development. In this study remote sensing and Geographic Information System (GIS) techniques were used to generate information on the current status and utilization potentials of the Kubili watershed and generate local specific micro watershed development plans for the area. The study revealed that about 33.25 per cent of the land cover is used for rain fed agriculture that lacks sufficient soil and moisture to support good yield. The drainage density …
