Some aspects of water balance indicators in Western Central Africa: example of the savannas in the Niari valley (Congo)
Shrubby savannas of the Niari valley are an ecosystem form that have a weak predisposition to evapotranspirate water in the atmosphere. They seem to be a “reducing” environment of energy transformation. The interactions of the soil-vegetation-atmosphere system seem to be largely dependent of surface conditions. What mostly explains the weakness of recycled moisture over this local area (at a local space scale). That partly leads to a high variability of the field capacity which fluctuates between one and five months. Moreover, shrubby savannas of the Niari valley are characterized by a continuous seasonal dryness. It is the result of a climatic azonality characterized by weak rains combined…
