Flood Assesment and Monitoring of the River Benue Cannel

This paper presents the findings of a comprehensive assessment and monitoring study of floods in the River Benue channel from 2015 to 2022. Floods are significant natural disasters with global impacts, and Nigeria, particularly the River Benue channel, is susceptible to recurring and severe flood events. The study employed advanced geospatial technology, including satellite imagery and remote sensing, to generate flood extent maps for each year. These maps were analyzed to determine the spatial distribution and intensity of flood events, and inundation frequency was calculated to assess the recurrence of floods. The results reveal significant variations in flood patterns and impacts across different years and states along the River Benue. In 2015, widespread inundation was recorded in all states, signifying the severity of flooding during that year. Subsequent years exhibited fluctuations in flood intensity and spatial distribution, with some states experiencing higher intensity than others. The most severely affected locations varied from year to year, with notable occurrences in Adamawa, Taraba, Kogi, Nasarawa, and Benue states. The study's implications underscore the localized nature of flood events and the need for context-specific flood management strategies.
