The Effects of Gully Erosion on Infrastructural Facilities in Gboko Township of Benue State, Nigeria.
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 9
Abstract
This study examined the effects of gully erosion on infrastructural facilities in Gboko Township to ascertain the magnitude of gully effects on infrastructural Facilities. Gullies were purposively selected from each of the five (5) unit of the town, Gboko north, south, east, west and Gboko central. Data collected were analysed using inferential statistics of mean, standard deviation, coefficient of variation and correlation matrix. Results of the analysis indicate that the gullies were both narrow U and broad U shape, gully dimensions and elements were varied. The correlation between cross sectional area, soil loss and slope angle has the high positive correlation of 0.958, 0.968 having an r2 of 0.975 respectively. The correlation between gully length and gully depth, gully width, shoulder width, slope angle, cross sectional area soil loss indicate 0.588 0.534,- 0.113, - 0.154, 0.0525) having r2 of (0.958, 0.927, 0.570, 0.968) respectively. The impact of gully erosion on electricity poles and water supply is less visible while the streets, bridges/culverts are the most affected since their maintenance is very poor. The study concludes that gully erosion has affected infrastructural facilities in the study area. It recommends that adequate effort be made both by government and individuals to prevent the occurrence of gully erosion by planting cover vegetation in the areas that are found to be open. Proper channelization be made with a view to channel the excess water from paved surfaces.
