If the selected standard is higher than the range listed in Table 2.2.10, a special demonstration should be made to prove its economic rationality. The design flood standards for flooded objects such as railways, highways, power, water conservancy facilities and cultural relics not listed in Table 2.2.10 shall be determined in accordance with the provisions of professional specifications.
2.2.11 The boundaries of resident migration and land acquisition shall be based on the overall situation of the impact range of the above-mentioned reservoirs, such as frequent flooding and temporary flooding, flooding, temporary shore, landslide, etc., and follow the principles of safety, economy and convenience for production and life: Comprehensive analysis and demonstration shall be determined: 2.2.12 In the dam front section where the backwater effect is not obvious, the wind and wave climbing, ship wave 62 The reservoir submergence area shall include the regular submergence area below the normal water storage level and the temporary submergence area above the positive zone water storage level that is submerged by the backwater of the reservoir flood and wind and waves, ship waves, ice jam water, etc.
2.2.3 The determination of the temporary submergence range of the reservoir design flood backwater shall be based on the backwater elevation along the outer envelope composed of the natural flood above the dam site and the flood backwater level of the same frequency (flood season and non-flood season) designed after the reservoir is built. If the reservoir water level is lowered during the flood season, the backwater level of the front section of the reservoir is lower than the normal water storage level, and the normal water level elevation shall be used. The design terminal position of the reservoir backwater end shall be within the range of the backwater curve at the reservoir tail not higher than the natural flood water surface line of the same frequency by 0.3m, and generally can be horizontally extended to intersect with the natural water surface line. The determination of the design flood backwater level of the reservoir should also take into account the impact of 20-30 years of sediment deposition based on the amount of river sediment transport, the reservoir operation mode, whether there is a regulating reservoir upstream, and the importance of the affected object. 2.2.4 The wind and wave impact area should include the area where the reservoir bank is affected by wind and waves and ship wave climbing. For reservoirs with open reservoirs and long wind distances, the impact of wind and wave climbing should be considered on the basis of normal water storage level, depending on the topography and geology of the reservoir bank, residential areas and 5
clothing use. The impact range can be determined by the wave height calculated based on the 5-year to 10-year return wind speed during the normal water level retention period (see Appendix B for wind and wave height calculation). The ship's wave, according to the relevant professional regulations, is:
2.2.5 The ice jam water area should be determined according to the average water level of the reservoir when a large number of ice flowers appear, the average flow rate into the reservoir and the amount of ice flowers passing through, combined with the Yongshui curve calculated during the river closure period and the river opening period.
2.26 The impact area after the reservoir is filled with water, including geological disasters such as flooding, coral reefs, landslides, and other areas affected by the reservoir. 2.2.7 The scope of flooding should be reasonably determined in conjunction with relevant departments through comprehensive investigation and research based on the results of hydrogeological surveys and the groundwater burial depth allowed by different economic objects. 2.2.8 For areas where bank collapse and landslides may occur, their engineering geological and hydrogeological conditions should be identified, and on the basis of considering the law of reservoir water level fluctuations, the initial (5 to 10 years) and final possible landslide ranges should be predicted to study whether to take measures to deal with them. 2.2.9 The impact area of ​​reservoir flooding should also include the impact area caused by backflow of reservoir water and flooding in the valley soluble rock depressions in the karst landforms around the reservoir: the reservoir area that loses production and living facilities after the reservoir is dehydrated, the isolated island and the downstream river channel dehydration affected by the flooding of the flood-type power station reservoir. 2.2.10 The design flood standard for land acquisition and resettlement of reservoirs should be analyzed and demonstrated according to the importance of the objects, the regulation performance of the reservoir and the use mode. Under the principles of safety, economy and considering the original flood control standards, the design flood standard range listed in Table 2.2.10 should be selected according to local conditions. If the selected standard is higher than the range listed in Table 2.2.10, a special demonstration should be made to prove its economic rationality. The design flood standards for flooded objects such as railways, highways, power, water conservancy facilities and cultural relics not listed in Table 2.2.10 shall be determined in accordance with the provisions of professional specifications.
