GARCIA LEMMO, Rafael; MARCO PARRA, Lué Merú; TORRES SIERRALTA, Gosmyr Gabriella  e  YACELLI ACEVEDO, Grecia Aurora. Contaminant dispersion at Tumaque basin between Lara and Yaracuy in Venezuela. RIHA [online]. 2014, vol.35, n.2, pp. 79-93. ISSN 1680-0338.

The WASP 7.4 model was applied to the Tumaque basin (Lara and Yaracuy states, Venezuela), to evaluate contaminant dispersion. The geographical characterization of the basin was made considering spot and diffuse sources for sampling points with the aid of Google Earth. Physical, chemical and biological characterization of the waters was carried out. For the hydrodinamic model, the water body was divided into 12 cells. The calibration was performed using two tracers: total dissolved solids and chlorides. The differences between determined and predicted values was 6% when dissolved solids is used as a tracer for the control point at Entrada al Eneal.

Palavras-chave : Tumaque basin; contaminant dispersion; hydrodynamic model.
