| Résumé anglais |
The streamflow of the Nile river, like those of the others waterways which pass through the Sudano-Sahelian zone, has been considerably strucked down in 1972, 1973, 1983 and 1984. The hydrological drought has brought on a water shortage characterized by a degradation of the streamflow of the river Nile, a lowing of the fluvial underground water table, an abnormal depletion of soil moisture and a damage of the fluvial environment (erosion and undermining of banks, withering of the fluvial vegetation, decrease of the river fishing) in the river Nile valley.
