Description :
The purpose of this study was to analyse if the colour of soils on granito-gneissic bedrock of West Africa could give some simple indicators of the duration of soil waterlogging. A toposequence on a representative hillside in central Togo was studied by means of 19 hydropedological stations. Soil and piezometric conditions were studied on these stations for 3 annual cycles (1989-1992) during which rainfall conditions were representative of the mean rainfall conditions for that hillside. The operational limits of logistic models for predicting the mean annual rate of soil waterlogging are discussed.
