Abstract

In this work, we report on an investigation that attempted to address the gully erosion problems of the Nanka - Adazi-nnukwu - Agulu area of Anambra State, Nigeria. With serious erosion leading to deep gullies occurring at unprecedented rates in many parts of Nigeria especially in Anambra State of the country, due partly to the lack of understanding of the erosion processes, and partly to lack of prompt appropriate action by the agencies responsible for its management, the need to properly manage or mitigate its effects has grown. Addressing this problem requires a target-oriented and clearly structured procedure. Simultaneously, it will be necessary to meet relevant legal, engineering, and environmental requirements and to produce designs that are environmental-oriented. The implementation of the erosion-hazard management and the integration of such a management instrument into an existing system, in addition to the use of modern technologies and procedures can help minimize the expanding erosion gullies and solve the erosion problem. The erosion hazard management process proposed consists of three phases: erosion hazard identification, erosion hazard analysis/assessment and erosion hazard handling which are based on each other.
