“…O volume de sedimentos em um reservatório pode ser avaliado por meio de modelos empíricos (BORLAND; MILLER, 1960;SLOFF, 1991SLOFF, e 1997 ou matemáticos (USACE, 1972;ZHOU;LIN, 1998;CAMPOS, 2001;WU;VIEIRA;WANG, 2004;LAQUINI, 2009). No entanto, estes modelos, apesar de muito úteis, só fornecem uma avaliação preliminar do volume de sedimentos depositados, uma vez que a solução precisa do problema é muito complexa e requer informações muitas vezes indisponíveis.…”

“…This 1-D model was validated by simulating sedimentation processes during drawdown of the reservoir. CCHE1D (Center for Computational Hydroscience and Engineering) is an integrated flow and morphodynamic model developed by the National Center for Computational Hydroscience and Engineering (NCCHE) at The University of Mississippi (Wu & Vieira, 2002;Wu et al, 2004). The model simulates non-uniform sediment transport, bed aggradation and degradation, bed material composition (hydraulic sorting and armouring), and bank erosion.…”

“…These models have ranged from simple conceptual representations of transport in uniform flow in clear water (Vreugdenhil and de Vries 1973;de Vries 1973) to comprehensive representations treating transport in sediment-laden nonuniform and unsteady flow with interaction between suspended sediment and movable bed layer (Pianese 1994;Wu 2004;Wu et al 2004;Singh 2006, 2007). Such situations may be encountered during flash floods, landslides, and bank failures.…”

“…In such situations, not only the sediment transport but also the flow is unsteady and nonuniform, and sediment transport takes place under nonequilibrium conditions. For modeling such situations, the requirement of sophisticated numerical models are inevitable (Singh et al 2004;Wu et al 2004;Vasquez et al 2008;Aricò and Tucciarelli 2008).…”
