Abstract:
The objective of the present study consisted in the diagnosis of the physical conservationist deterioration of the microbasin of the Paus Brancos Stream, Campina Grande, PB, in the semi-arid region of Paraiba state. The microbasin was divided in 11 minibasin. The methodology consisted in determination of the rugosity coefficient (Ruggdeness Number - RN), using the physical characteristics of the minibasins and the distribution of land use classes using the rugosity coefficient. In the studied area the physical conservationist deterioration is high (34.91%), contributing to this the small vegetable covering 232.15 ha (10.05%). There is availability of many areas for the agriculture but their utilization depends on auxiliary diagnosis. Although there are only 172.37 ha (7.48%) in conflicts, for the perfect environmental equilibrium of the microbasin, 1,286.14 ha (55.68%) need to be worked out. No class A minibasin presented excess of agricultural area. The deteriorated area in the studied microbasin is 507.35 ha (21.97%).
