AN ALTERNATIVE FOR FLOOD CONTROL IN THE ICARAÍ RIVER BASIN, NITERÓI CITY, RIO DE JANEIRO, BRAZIL

Resumo

This paper demonstrates that it is possible to implement a flood control system (called “piscinão”) in Niterói city, located in Rio de Janeiro State, Brazil composed by a reservoir that retains temporally the storm water. The recommended design storm equation and flood routing were applied in order to design the reservoir capacity. The results indicate that it is feasible to implement such solution, reducing more than two thirds of the peak discharge downstream, thus mitigating the damages caused by flood in Niterói city.
