摘要：Remote sensing and GIS based results from the geometric characterization of pointbar deposits in the Lower River Niger are presented in this work. In this study thegeometry of 75- point bar deposits from Landsat images of 1985 and 2015 weredocumented and compared to determine the relationship that exist betweengeometric dimensions and the amount of change that has occurred on them. Pointbars in 2015 are observed to be greater in length, width and area than those in 1985.The R² values indicate that no relationship exists between point bar length and width.However, a significant relationship is observed to exist between both length andarea and width and area of the point bars within the study area. Thus, the utilizationof width to predict the length and vice versa of point bars is unreliable. Informationfrom this study provides useful information on specific shape and size ranges thatcan be utilized for the efficient characterization and development of hydrocarbonreservoirs.
