BELTRAN VARGAS, Julio Eduardo. Modeling of primary production of phytoplankton in the wetland Jaboque, Bogotá D.C.. Tecnura [online]. 2016, vol.20, n.47, pp.85-95. ISSN 0123-921X. https://doi.org/10.14483/udistrital.jour.tecnura.2016.1.a07.
A dynamic simulation model is presented to explain the general behavior of the primary production of phytoplankton in the wetland Jaboque-Bogota, Colombia, in three sections with differential physical and chemical characteristics. The model takes into account the physicochemical variables, the basin area, depth, annual rainfall, water temperature, pH and concentration of chlorophyll _a. The dynamic modeling is based on differential equations and the Euler integration method is used, the modeling was developed using Stella 9.1® computer program. The model allows quantifying the primary production of phytoplankton in wetland Jaboque from chlorophyll _a monthly average concentration for each section. The results of the Ppf modeling show that Ppf concentration variations in each section of the wetland follow a reverse pattern to the bimodal behavior of precipitation. A high degree of correspondence between the values of chlorophyll_a Ppf field and modeled in the following manner r2 = 0.86 for the first section and r2 = 0.86 and r2 = 0.79 for the remaining sections was found. Error determination was 0,57 relative to the first section and 0,35; 0,46, indicating that the results are not overstated. The model shows in general terms the functional aspects of behavior Ppf and its relation to the process of eutrophication, and it allows recommendations for the management and restoration of wetlands.
