  abstract = {{T}his study provides the first numerical simulation of physical and biogeochemical processes in a very turbid and highly eutrophic tropical reservoir of the {T}rans-{M}exican {V}olcanic {B}elt in {M}exico. {T}he {C}ointzio reservoir (capacity 66 {M}m(3)) is characterized by a lack of water treatment plants upstream and a high content of very fine clay particles. {I}t suffers serious episodes of eutrophication associated with high levels of turbidity and benthic anoxia. {D}ifferent scenarios for future climate inputs, nutrient inputs and water levels were simulated. {T}he results pointed out the potential negative long-term impact of climate change on this reservoir. {I}n this region, an increase of average air temperature as high as 4.4 degrees {C} is expected by the end of the century. {W}hen coupled with a low water level, this increase could lead to critical conditions with a severe depletion of dissolved oxygen and important algal blooms with chlorophyll a reaching values of up to 94 mu g {L}-1. {T}he calculations indicated that a drastic reduction of nutrient inputs (up to 90%) would be required to significantly reduce chlorophyll a concentrations. {I}f such mitigation measures are adopted, the maximum peak of chlorophyll a would be reduced by 55% after a ten-year period of efforts, with corresponding positive effect on dissolved oxygen concentrations. {T}he main limitation of the chosen numerical approach comes from the assumption of a constant water level in the model. {T}his may be particularly critical for shallow type reservoirs. {W}hile this region remains poorly studied, this study brings original information that will help stakeholders to adopt appropriate strategies for the management of their waterbodies that experience critical eutrophication.},
