Resumen
This paper presents a study of the physical characterization through morphometric analysis of the Bosque Stream basin, inserted into the GrãoMogol State Park, in the city of GrãoMogol. Bosque Stream is one of the main sources of water of GrãoMogol State Park, which in turn plays a strategic role in the city water recharge and conservation of local biodiversity. The morphometric indexes were obtained through the use of topographic maps, satellite image, equations, and specialized software. The characterization of the basin results in relationships of numerical indexes of different attributes, allowing us to evaluate their inter-relationships and perform a more consistent water analysis. The morphometric parameters indicated that the hydrographic basin under study has circular shape (Ic = 0.64), with increased susceptibility to flooding, as evidenced by the form factor (0.59) and the coefficient of compactness (1.24), which reinforce the medium tendency to flooding, in which these, if they occur, may be huge. The results suggest the efficiency in environmental interpretation of the Conservation Unity and, obviously, the improved effectiveness in its management. This study may also contribute to the elaboration of the unit management plan.
