Fig. 2 Talweg Longitudinal Section 3.2. ANALYSIS OF THE SEDIMENT-CAUSED STORAGE CAPACITY LOSS Now, the storage results calculated and measured by the topographic map before the reservoir construction, in 1996, 2005, 2009 and 2014 have been collected, as well as the results of the cross section survey of the reservoir before the reservoir construction, in 1996, 2000, 2003, 2005, 2009 and 2014, and the method of section is applied to calculate the storages over the years. In order to eliminate the errors caused by the two calculation methods, the storage capacities calculated by the method of section in 2000 and 2003 shall be corrected, and the calculated characteristic capacity and sediment-caused storage capacity loss are shown in Fig.3 and Table 1.
