Physicochemical, primary production and trophic state variation of an urban artificial water body located in the central zone of the tropical latitude of Mexico

Abstract

Artificial water bodies at tropical latitudes have regular or extreme water contributions dependent of climate and interannual variations that result in differences in the physicochemical characteristics of the water; in addition to the climate. They receive peripheral runoff two, according to geomorphology; in the case of Mexican artificial water bodies as Cantera Oriente, they will also depend on the orography that entails changes in the volumes of water. All of this influence in conservative and non-conservative physiochemical components through dilute the water in the rainy season and concentrate it in the dry season. Therefore, this paper estimates the variations of: temperature, conductivity, dissolved oxygen, pH, with nutrients (total phosphorus and nitrogen, chlorophyll “a” and primary production). In the Cantera Oriente all this parameters resulting in an oxic and anoxic condition, as well as a widely variable hypertrophy, depending on the month of year, in addition, anthropogenic sewage runoff must be added.
