ABSTRACT: Register in the framework of the International Program of Research
on Water Resources Management and Protection of Ecosystems, the Congo basin in
which lies the catchment area of the Kadey (2647 km2) was selected to better
assess the impact climate variability on the water surface in the perspective
of supply drinking water both in the rainy season and in periods of low water.
Based on new data from rainfall and flow rates obtained in the last fifteen
years (1998-2013), the major trends in time series and the scope of the
“drought” were identified. The historical rainfall in the basin is
characterized by two major ruptures rainfall in 1969 and 1999. These have
generated an order deficit of 14% respectively and an excess of nearly 19%.
These phenomena also affected the recurrence of cumulative rainfall throughout
the Kadey basin. Here, the hydrological response to excess rainfall is over
100%. However, it appears that over the period 1970-2012, the number of years
that has undergone a “severe drought” is to play down.
