Flood Risk Assessment and Disaster Management through Data Applications and Engineering Interventions

Abstract

Flooding is the most extreme and well-known destructive tournament and has serious implications for sustainable development. The vast majority of disasters in Africa are caused by floods, which are also the most frequent and widespread calamities. This paper x-rays alternative approaches to catastrophe management and flood risk assessment. Various methodologies, literature reviews and advanced techniques such as remote sensing, indicator-based methods, computer-based methods and utilization of geographic information systems (GIS) and other approaches in disaster management and flood risk assessment in Nigeria. Floods result in significant losses to property, infrastructural decadence, and the prevalence of diseases. Lack of sufficient capacity building, good spatial planning, strategic training, inconsistent government policies, and erratic land-use management are major challenges. Flood Risk Index (FRI) is based on meteorological and socioeconomic information. The frequency and severity of natural disasters have sharply increased in recent years, putting large populations at risk in a variety of environments and raising worrisome worries across the globe. Flood risk assessment and disaster management around hydraulic structures such as dams can be achieved through effective inventory, data applications and other engineering interventions. Indicator-based methods; GIS-based spatial planning, Community-Based Disaster Mitigation (CBDM) and land use management strategy are recommended as viable solutions.
