INTRODUCTION

Hydrological flow situation in the Niger basin during the month of November was
characterized by a continued increase of flows in the Middle Niger. In the same time the flow at the Upper Niger, the Inland Delta and the Lower Niger was decreasing.

The flow analysis situation was carried out by dividing the basin into four sub‐catchments also represented with reference gauging stations as follows: Upper Niger at Koulikoro (Mali), Inland Delta at Dire (Mali), Middle Niger in Niamey (Niger) and Lower Niger at Lokoja (Nigeria) as shown in figure 1.

Figures 2 to 5 and Table 1 show respectively, the comparative hydrographs for hydrological years 2011/2012, 2012/2013, 2013/2014 and 2014/2015 as well as the five‐year wet and dry return periods and mean at the references stations.
