A GIS Multi-Criteria Evaluation for Flood Risk-Vulnerability Mapping of Ikom Local Government Area, Cross River State
Flooding is a significant hydrological hazard in the world and has elicited responses from government and non-government agencies alike due to the damages it portends. This study was formulated on this backdrop, with the objective of designing a flood risk-vulnerability map of Ikom Local Government Area. The types of data employed were majorly secondary. Interviews were also primarily adopted. The multi-criteria assessment meant a systematic combination of independent parameter inpu...
Increased Paved Surfaces as Major Factor of Urban Flooding in Humid Tropics: An Example from Calabar, Cross River State, Nigeria
Urban flooding is a major hydrological hazard in most cities of the humid tropics due to high amount of rainfall, unlike in Polar Regions. However, recent increase in flooding menace has been attributed to human activities. This paper presents new insights on the condition of the built-up surface as the major factor of flooding in humid tropical cities using geospatial technology, with Calabar as an example. The study area was first classified, using the unsupervised algorithm into ...
