Channel Sinuosity Effects on Inland Transport in the Riverine Region of Ilaje, Nigeria

Transportation is an essential tool for regional social and economic growth, as well as national development. Transport has a vital social and environmental impact that cannot be overlooked. The character of naturally functioning rivers varies greatly and does not remain constant since it is mainly determined by several of physical factors and processes, among which is river sinuosity. Understanding how the inland waterways change with time and the effect or consequences of these changes on the lifestyle and economic activities of the inhabitants becomes very important. This study focused on revealing the changes that had occurred in the planforms of Igbokoda-Idiogba/Ayetoro waterways in Ilaje, Ondo state; its effects on inland transport taking cognisance of sinuosity index. It assessed morphological changes of navigable rivers in the study area from 1972-2022; the effects of river sinuosity on inland transport in the study area were considered. The study deployed geospatial techniques to assess the decadal changes of changing patterns of the channel’s sinuosity taking cognizance of the sinuosity index and formula. However, the study shows the capabilities of geospatial techniques in monitoring river morphology. The study revealed significant changes in the channel’s sinuosity and consequential effects of the changes. Sustainable transport measures for safety and efficiency were recommended.
