Fig. 5 Comparison of Sedimentation Longitudinal Sections of the Manwan Reservoir in 2003 (model verification) 4.3. SEDIMENTATION FORECAST 4.3.1 CALCULATION DATA AND PARAMETERS FOR SEDIMENTATION (1) Longitudinal and Cross Sections of the Reservoir Area The longitudinal and transverse profiles of the reservoir area were surveyed by the Surveying and Mapping Branch of the Kunming Engineering Corporation Limited of Power China from April to May 2014, and the layout of the profiles for scouring and silting calculation of the reservoir is shown in Figure 6, with 71 profiles in total. The section spacing is between 75m--- 1,321m, which can satisfy the calculation requirements. Compared with the measured data in 2009, there are 8 sections less in the end area of the reservoir; and combined the comparison of the calculated results in 2009 and 2014, the scouring and silting in river of the end area of the reservoir changed a little; hence the measured results in 2009 shall be applied for the 8 sections. 342
