- Abstract
Understanding and representing the behavior of the hydrological cycle of a river basin have a great importance for an efficient management of its resources and the use of hydrological models come to contribute in this sense. Therefore, the objective of this work is to estimate sediment yield in the Epitácio Pessoa Reservoir basin in Paraíba, a basin that is suffering from long periods of water scarcity and sediment yield. The study was carried out for the period 2001 to 2014, using the SWAT model. The mean simulated flow for the period was 12,87 m³/s and the estimated average sediment yield for the basin was 0.03 (ton/ha-1.year-1) during the 14 years analyzed. Based on the estimates, the total sediment deposited in the reservoir was approximately 434 thousands tons in 14 years. Thus, it is necessary to use policies to reduce sediment production in the basin and consequently minimize the silting process of the Epitácio Pessoa reservoir, which over the years has been causing a decrease in its total storage capacity, originally of 535.680.000 m³ (DNOCS, 1963), and today according to the AESA is 411.686.287 m³.
