Nowadays, the management of water capital becomes an alarming situation, worrying the authorities of many countries. The purpose of this study is to assess the capacity of the Kisanga II aquifer in order to serve the population of the city of Lubumbashi with water of sufficient quality and quantity in order to reduce the shortage of water. Hydrological observations were made over a period from 2014 to 2015. They reveal the behavior of the aquifer during the critical periods (dry season, dry episodes). From these observations, the authors describe the morphological and morphometric characteristics of the catchment drained by the river KISANGA II; evaluate the reserves of the aquifer of the basin, using the flood hydrograph raised by them; Then they discuss the significance of these results obtained by applying the empirical formulas of MAILLET & WERNER, TISON & DUNSQUIT and then explain the index of storage and the rate of renewal; establishing the optimum conditions for the use of this aquifer in case of abusive exploitation and finally providing advice to the managers.

Abstract
Nowadays, the management of water capital becomes an alarming situation, worrying the authorities of many countries. The purpose of this study is to assess the capacity of the Kisanga II aquifer in order to serve the population of the city of Lubumbashi with water of sufficient quality and quantity in order to reduce the shortage of water. Hydrological observations were made over a period from 2014 to 2015. They reveal the behavior of the aquifer during the critical periods (dry season, dry episodes). From these observations, the authors describe the morphological and morphometric characteristics of the catchment drained by the river KISANGA II; evaluate the reserves of the aquifer of the basin, using the flood hydrograph raised by them; Then they discuss the significance of these results obtained by applying the empirical formulas of MAILLET & WERNER, TISON & DUNSQUIT and then explain the index of storage and the rate of renewal; establishing the optimum conditions for the use of this aquifer in case of abusive exploitation and finally providing advice to the managers.
Author Keywords: aquifer, hydrological observation, morphological and morphometric characteristics, basin, flood hydrograph.
