The delta deposition pattern is the most important and universal sedimentation type in reservoirs, yet it is still unclear to engineers and researchers concerned about its evolution, adjustment and preliminary equilibrium of the sedimentation. Taken the reservoir named Xi Luodu as a typical case study the whole deposition processes of the delta evolution can be divided into two stages according to the time the delta arrives at the dam site, corresponding to the formation of the wedged shape deposition. Sedimentation in the first stage composes the majority deposits of the reservoir total accumulation volume. Although in the second stage the deposition rate is much slower than the first one it is the period for the reservoir to rebuild its new equilibrium mainly by changing the configuration of its cross-section to regain sufficient sediment carry capacity. The delta profile and the cross-section deformation were both discussed in detail during the two stages. Characteristics of the deposition/erosion along with the sediment delivery ratio were also analyzed throughout the whole processes.
