dc.description.abstract Current understanding of small -scale physical processes , such as mixing , in tropical water bodies is lacking and observations are scarce at best . This study sheds more light on these processes through a combined observational -modeling approach . For this purpose , observations were made in Valle de Bravo's freshwater reservoir , about 100 km west of Mexico City and at an elevation of 1830 m above sea surface . Turbulence kinetic energy dissipation (TKED ) rates were estimated by fitting a theoretical Batchelor spectrum to the temperature gradient spectrum . From similarity scaling of dissipation rates , it was found that in the surface layer , winds were the main driving force in generating turbulence during the day , while convective forces were responsible during the night . Bottom boundary layer (BBL ) mixing was mainly driven by internal wave (first vertical and first horizontal mode ) breaking at the bottom . Lognormality of turbulence dissipation rates is also discussed for surface , intermediate and bottom boundary layers . For our modeling efforts , a state -of -the -art one -dimensional turbulence model was used and forced with the observed surface meteorology to obtain simulated temperature and dissipation rate profiles . The model results were found to be in good agreement with the observations , though minor differences in dissipation rates were found in the vicinity of the thermocline and the BBL . en_US
