| Summary: | The Piranhas-Acu River is one of the major routes of natural drainage basin Piranhas Acu. This river of federal domain, once born in the city of Bonito Santa Fe, state of Paraiba, and follows its natural course by the state of Rio Grande do Norte, emptying into the Atlantic Ocean in Costa Potiguar. In order to characterize the sediment and measure their transport by Rio Piranhas, from its geometric characteristics and bed material sampled was held sieve analysis and calculated the transport through the bed of empirical formula. The equation used was that of Meyer-Peter & Muller (transport in the bed). The equation of Meyer-Peter & Muller produced results that apparently follow the variation in grain size of the sediment from the riverbed. Equations to estimate sediment transport in the river may not have an adequate accuracy due to problems in the fluvial system. |
