Desenvolvimento do hidrograma unitário da bacia do rio Mamuaba.

Abstract

The present study is aimed at developing the Unit Hidrograph of the river Mamuaba for the section corresponding to Fazenda Mamuaba utilizing the precipitation and run off data of 3 years (1972, 1973, 1974). The derivation of the Unit Hydrograph was done by a selection of 5 simple hydrographs of complex storms by estabilishing a run off coefficient of each part of the precipitation. The resulting hydrograph have been discussed and their validity has been tested by simulating two complex hydrographs for actual precipitation. The influence of the coefficient of run off on the sensitivity of the derived Unit hydrograph has also been studied.
