【摘要】 无资料地区小流域河道管理范围划界工作是河湖划界的重要组成部分,但由于缺乏实测的水文资料,河道控制断面的设计洪水位无法由水位流量关系推求。探讨了推理公式法在无资料地区小流域河道管理范围划界中的应用,认为该方法可准确计算出各个断面设计洪峰流量,并结合实测断面资料,由洪峰流量计算设计洪水位。最后将此方法应用到敖家河小流域河道管理范围划界,计算所得的设计洪峰流量与洪水位成果合理,成功划定其河道管理范围。更多还原

【Abstract】 The demarcation of river management scope in small watersheds with no data area is an important part of river and lake demarcation. However, due to the lack of measured hydrological data, the design flood level of river control sections cannot be derived from the relationship between water level and flow. This paper discusses the application of the inference formula method to the demarcation of river management scope in small watersheds with no data. It is considered that the method can accurately calculate the flood peak flow of each section design, and combine the measured section data to calculate the flood level from the flood peak flow. Finally, this method is applied to the demarcation of the river management scope of the Aojiahe small watershed. The calculated flood peak flow and flood level results are reasonable, and the management scope is successfully determined.更多还原
