Proposta do sistema de drenagem urbana para o bairro Centro 1 da cidade Irecê-BA.

Abstract

With climate change, it can be seen that rainfall intensities have increased over a short period of time, and sanitation methods are being developed to minimize problems generated by large outflows without proper runoff, and the method in question is Urban Drainage. Therefore, this work had the objective of elaborating a proposal of urban drainage for the main district of the city of Irecê in the state of Bahia, where there are great trade and the main hospital of all the region. First, the city's intense rainfall equation was calculated to calculate the project flow. From then on the center was divided into sections, since its total area is relatively large, totaling nine stretches, where calculations were made for sizing the gallery size and its depth. And, finally, the energy lines of all the stretches were obtained and adjusting when necessary the depth of the dimension of the greide, so that the line of energy adapted.
