River flooding has become a widely distributed and devastating natural disaster that has caused significant damages both economically and socially. Recently, it displaced millions of people in Nigeria and submerged several square kilometres of landed area in general and farmlands in particular. Although, the National Emergency Management Agency (NEMA) predicted the occurrence of the flood disaster and advised the relocation of residence from the floodplain to the high ground, but spatial information pertaining to the areal extent vulnerable to the hazard was not made available. This study attempted to assess the spatial impact of the October 2012 flooding of the Niger-Benue basin on the surrounding areas using the moderate resolution imaging Spectroradiometre (MODIS) data of NASA Terra satellite and developed a geospatial methodology for detecting and extracting the flood risk areas and the vulnerable population to flooding within the basin. The integration of remotely sensed data and other spatial and non-spatial data within the GIS platform was able to produce series of thematic maps which was used to generate a geospatial database for flood risk analysis and assessment. The result of the analysis effectively demonstrated the contribution of geospatial methods in mitigating and monitoring the effect of flooding along the Niger-Benue basin. It was therefore, suggested that government agencies and policy makers should adopt this powerful technique for reliable and well synthesized information which is a vital component of flood risk assessment and planning.

During humanitarian emergencies, well-timed information on affected populations is central in planning humanitarian responses and the optimum allocation of available resources. However, this is usually only available following an on-ground assessment which, in most of the cases, comes too late to contribute to the initial decision-making process that informs the first wave of humanitarian response. To address this problem, a spatial model was developed for the assessment of the flood-affected population in a near real-time scenario. A flood extent vector, extracted from MODerate resolution Imaging Spectroradiometer daily images, was superimposed on a LandScan population grid to estimate the population count living in the flooded area, aggregated by their respective administrative level. The methodology was found to be both timeand cost-efficient for riverine floods. The model was tested for its accuracy using an on-ground initial vulnerability assessment and the figures matched to within 80-90%. This model can be used with a confidence level of ±10% for riverine floods.

“…Often, simple approaches are used, mainly due to limitations in available data and knowledge on damage mechanisms. With the advent of geospatial technology that aid remote sensing, researchers have been able to investigate flood thoroughly [13,14]. The first integration of remote sensing with flood monitoring mentioned in literature dates back to the 1970s, where data from Landsat 1 helped to analyze the Mississippi flood of 1973 [15].…”

Floods, Landslides, Forest fire, Volcanoes, Hurricanes and Tsunami among others are indeed considered as the most natural hazards that cause loosed of resources which includes human lives. Hadejia-Jama' are River Valley has a well-known seasonal occurrence of floodings with maximum interval of five years incidents historically. Among these disasters floods especially along the river basin particularly in developing nations like Nigeria became a regular disaster with state of frequent occurrences almost seasonally. This study assessed pre-flood and post-flood nature of floodplain along Hadejia-Jama' are from Jigawa to Tiga Dam in Kano State. Remotely sensed sentinel 2 satellite data and ALOS Digital Surface Model (DSM) was used for the study. The sentinel images were subjected to image pre-processing activities such as geometric correction Odewole et al.; IJECC, 10(2): 34-44, 2020; Article no.IJECC.54640 35 and radiometric correction. To focus on the flood plain, a 5 km buffer of the area around Hadejia-Jama'are River Basin from Jigawa to Tiga dam were extracted from the data by using the extract/clip tools in ArcGIS 10.3 software. Findings of the study revealed that dominant land use along the floodplain prior to flood include bare surface, patches of agriculture/vegetation, settlement, water body. The study also revealed that patterns of flood damages vary irrespective of the risk with areas like Dawakin Kudu and Garun mallam were witnessing more flood damages than Miga LGA of Jigawa State. It is, therefore, concluded that Earth observation and its applications are useful tools/methods for flood damages assessment and evaluation as well as a basis for taking proactive steps in mitigating flood hazard along floodplains and another flood prone environment.
