Abstract

The Weija catchment in Ghana has been identified to exhibit signs of geological instability with frequent vibrations occurring in the area. The paper sought to assess residents’ knowledge of mass wasting in the Weija catchment using observations, field measurement and interview schedule with local residence. Both natural and anthropogenic factors were identified as the cause of mass wasting in the Weija catchment. Vegetation removal, excessive rainfall, sand mining, poor construction practices and location of structures as well as poor drainage systems were identified as the major causes of mass wasting in the area. Stress and anxiety, loss of property, destruction of roads was identified as the triggering effects of mass wasting in the Weija catchment. Measures to reduce mass wasting included appropriate construction practices, good drainage systems, afforestation and restriction on excavation on and at the hill basement. The paper recommends good engineering practices that takes into account the geology and morphology of the hill or landscape before buildings are erected.
