Abstract
With objective of to diagnose the deterioration socioeconomic, environmental and to evaluatethe morphometric characteristics of the microbasin of the Stream Happiness’s, the study areawas visited, applying itself questionnaires in a sample of the local population.

The microbasin has a more prolonged form, being proven for Ic060, Kc 0,98 and Kf of 0,15, besides Dd of 1,10 km/km2 and the declivity of the 1,20% basin.These associated values show an area without problems of inundations and erosions alongthe Stream. The indexes obtained don’t still demonstrate a high environmental deterioration.
