Floodplain wetland mapping in the White Volta River Basin of Ghana

2015

English

Apart from the earmarked Ramsar sites along the coastal zones of Ghana, no inventory has been conducted to determine the location, distribution, and status of wetlands within any of its river basins. In this study, a logistic regression model was used within the GIS platform to predict, at pixel level, the presence of a wetland in the basin of the White Volta River. The output consisted of a map and also indicated that a total of 259.5 km2 of the land mass is estimated as probable floodplain wetland sites. The model used resulted in a high level of accuracy in predicting wetland presence.
