%X A numerical approach to heat and mass transfer in a
large water reservoir is presented. This water reservoir is likened to a
parallelepiped reservoir whose vertical and lower walls are adiabatic and
impermeable. The equations that govern natural convection in water are solved
by the finite volume method and Thomas¡¯salgorithm. The adequacy between the
velocity and pressure fields is ensured by the SIMPLE algorithm. We are going
to evaluate the water losses by evaporation from three dams in the Nakanb¨¦
basin in Burkina Faso for a period of thirty years, that is to say from January
1, 1991, to March 15, 2020. The three dams
have a rate of evaporation greater than 40% of the volume of water stored.
Indeed the rate of evaporation in each dam increases with the water filling
rate in the reservoir: we have observed the following results for each dam in
the Nakanb¨¦ basin; for the date of 02/27/1988 to 03/13/2020., the Loumbila dam
received a total volume of stored water of 22.02 Mm3 and 10.57 Mm3 as the total volume of water evaporated at the same date. At the Ouaga dam (2 + 3), it stored a water volume of 4.06 Mm3 and evaporated 2.03 Mm3 of its storage volume from 01/01/1988 to
05/07/2016. Finally, with regard to the Bagr¨¦ dam, it stored 745.16 Mm3 of water and 365.13 Mm3 as the volume of water evaporated from
01/01/1993 to 03/31/2020.
