BELTRAN-VARGAS, Julio Eduardo  e  RANGEL-CH., Jesús Orlando. Dynamic modeling of total suspended solids in the wetland Jaboque, Bogotá (Colombia). Colomb. for. [online]. 2012, vol.15, n.2, pp.191-205. ISSN 0120-0739.

We propose a dynamic simulation model to provide a general explanation for the behavior of total suspended solids in the Jaboque wetland (Bogotá DC). The analyses were performed in three areas with distinct physical and chemical characteristics. The model predicted concentrations of total suspended solids in the months of April, May, June, October and November. Values ranged from 85 mg L^-1 and 101 mg L^-1 with an average of 65.12 mg L^-1 with a hydraulic time retention between eight and nine days per year for the first area, the second area between 57 and 69 with an average of 50 mg L^-1 with a hydraulic time between 20 and 23 days per year and in the third area between 56 mg L^-1 and 67 mg L^-1 with a mean of 48.8 mg L^-1 and a hydraulic retention time between 24 and 26 days per year. The months of December, January, February, August and September showed a tendency to have lower values. The estimated values of total suspended solids based on our model had an acceptable correspondence, R² = 0.95, 0.71, 0.67, with the actual values in all cases. The relative error for each area was 0.10, 0.20 and 0.26, demonstrating that the model does not overestimate the results.
