Influence of Infiltrations on the Recharge of the Nkoabang Aquifer Located in the Center Region, Cameroon

Due to the limited reach of drinking-water delivery network, Yaoundé’s surrounding communities (such as Nkoabang) rely on well water, boreholes, and springs. This study conducted a Thornthwaite water-balance analysis in watershed order understand its hydrology capability investigated influence flows infiltrations recharge aquifer Nkoabang (Centre Region, Cameroon). The methodology this work consisted updating rainfall temperature data Mvan meteorological station Yaoundé carry out hydrological water balances performing piezometric monitoring seven wells one spring dry season rainy season. average height for period between 1951–2017 was 1577 ± 222 mm, while monthly temperatures ranged from 22.8 (July) 25.4 °C (February) an 24.1 0.8 °C. interannual infiltration 137 corresponding coefficient 8.68%. value levering varies 706 718 m 711.76 during It fluctuates 719 712.95 4.09 m. Irrespective season, highest lowest values are those P6 P3, respectively. Piezometric level vary little another but higher than Wells area generally show small variations amplitude, ranging 0.4 3.3 with 1.19 1 map shows flow NE-SW direction; storage areas south supply peaks NE Nkoabang. daily indicative rates (S) 0.15 m3 (dry season), which can seasons 36 46 people, respectively, based ratio 0.1 per day habitant.
