sensing and GIS based results from the geometric characterization of point bar
deposits in the Lower River Niger are presented in this work. In this study the
geometry of 75- point bar deposits from Landsat images of 1985 and 2015 were
documented and compared to determine the relationship that exist between
geometric dimensions and the amount of change that has occurred on them. Point
bars in 2015 are observed to be greater in length, width and area than those in
1985. The Rē values indicate that no relationship exists between point bar
length and width. However, a significant relationship is observed to exist
between both length and area and width and area of the point bars within the
study area. Thus, the utilization of width to predict the length and vice versa
of point bars is unreliable. Information from this study provides useful
information on specific shape and size ranges that can be utilized for the
efficient characterization and development of hydrocarbon reservoirs.
