ANÁLISE DA ESTABILIDADE LATERAL EM TRECHOS FLUVIAIS DA BACIA RIACHO DO TIGRE, SEMIÁRIDO PARAIBANO

Abstract

The research analysed de lateral stability in Paraiba semiarid fluvials environment at the Tigre stream catchment. The principal objetic was study the capacity of lateral adjusts and his relationship with the margins by texture and consistency tests, being also realized vegetal covers analysis and energy distribution analysis. From the eigth parts evaluated, two of them was classified as steadies; four of them, unsteadies; and two with intermediary stability. From the results was possible conclude that the vegetation develop a fundamental function at the stability of the margins, because even in the poorly bonded composite margins were not identified indications of erosion process caused by the resistence exercised by the vegetal cover.
