ROMAN-BOTERO, RICARDO; GOMEZ-GIRALDO, ANDRÉS  y  TORO-BOTERO, MAURICIO. SEASONAL EFFECT OF TRIBUTARIES ON THE THERMAL STRUCTURE OF A SMALL NEOTROPICAL RESERVOIR, LA FE - COLOMBIA. Dyna rev.fac.nac.minas [online]. 2013, vol.80, n.177, pp.152-161. ISSN 0012-7353.

We investigated the seasonal evolution of the thermal structure of La Fe Reservoir based on field data and weather variables collected in 2010 and 2011 and the application of the hydrodynamic model ELCOM. The reservoir receives contributions from natural sources and water through a pumping system during the dry periods. We found that there is not a relevant influence of the annual cycle in the atmosphere-lake heat fluxes, although there were measurements during El Niño, transition, and La Niña. The observed changes in the thermal structure are mainly due to the hydrological conditions of the inflows and the operation of the pumping system. It was found that the northern basin is dominated by the dynamics of the natural inflows and water withdrawal, while in the south basin dynamics is dominated by the imported water.

Palabras clave : tropical physical limnology; neotropical limnology; thermal structure; La Fe reservoir.
