Reservatório para contenção de cheias no Mercado Central e Canal do Portinho em São Luís-MA

Abstract

Floods and the overflow of water on dry land have always been part of our life on earth. "Almost every civilization has a story about a great flood, since ancient times, people have built their cities on the banks of rivers, because they use water to drink and to irrigate their crops". For this reason, floods and rivers affect numbers of people, in some places, people have built dams or dams to protect lands against river floods and to create reserves for the driest periods, after much rain the soil is soaked and it loses the ability to absorb all the water that falls on it, that water then flows to the lowest places, ending up in rivers and streams, and consequently filling cities, making victims and leaving thousands of people without homes and belongings. The neighborhoods of São Luís suffer from heavy rains, the level of the Bacanga River, one of the main rivers in the state of Maranhão, rises almost five meters from the normal level, causing floods in the Central Market. The implementation of swimming pool structures for draining and draining rainwater would be sufficient for the containment of rainwater in the Central Market and Canal do Portinho in São Luís-MA.
