Estudo hidrometeorológico na bacia do rio Mundaú, Alagoas e Pernambuco

Abstract

This work was carried through in the Hydrographical Basin of the River Mundaú, located in the States of Alagoas and Pernambuco, being overcome as base, given of fourteen pluviotrics and a station for measure fluvial, located in this basin, the period of 1965 until 1985 for precipitations and period of 1965 until 2002 for outflows. Ther average precipitation of thebasin was calculated through the method of Thiessen, as well as the precipitation regimen of the study área, then after, was calculated probable maximum precipitation, through the Distribution of Probability of Gumbel or Extreme Values, verifying also the period of return. Also the space distribution of the precipitation in the área of the basin was analyzed, through figures generated for software to Surfer version 7.0. The regimen of outflow of the basin was observed, analyzing it’s annual, monthly and sazonais variations, became the calculation of proble the maximum outflow, throug the Distribution of Extreme Values of Gumbel and was analyzed tjhe period of return for the observed maximum outflows. A was created one Curva-Chave (Key-Curve) for in the River Mundaú, in which revealed sufficiently trustworthy, due the good joined correlation. All these results Will make with that let us can understand this ecosytem better and to try to modify the process anthropomorphous in which the basin comes passing.
