本次调查河流属水文资料较缺乏的河流,是在参证站宁家河渠首水文站多年实测水文资料的基础上,通过实地水文调查与勘测,根据国家行业有关规范,对该河段进行的洪水调查分析。主要依据国家行业标准《水文调查规范》(SL 196-1997)、《水文普通测量规范》(SL58-1993)等技术标准和规定进行。根据对历史暴雨洪水的对比分析研究工作,全面分析暴雨成因、洪水成因、洪水发展过程、进而对洪水量级做出分析评价。通过野外调查测量考证和分析历史暴雨洪水,通过分析论证,确定该河流河段历史洪峰水位和流量与本次所调查分析的洪峰流量基本一致。
The survey of rivers is a lack of hydrological data of the river, is in reference station Ning Jiahe hydrological station hydrological station for many years based on the measured hydrological data, through field hydrological surveys and surveys, according to national industry standards, carried out on the river Flood investigation and analysis. Mainly based on national industry standards “hydrological survey” (SL 196-1997), “General Hydrological Survey” (SL58-1993) and other technical standards and regulations. Based on the comparative analysis of historical storm floods, this paper comprehensively analyzes the causes of rainstorms, the causes of floods and the development of floods, and then makes an analysis and appraisal of the magnitude of floods. Through the investigation and measurement of the field investigation and analysis of historical storm floods, through analysis and demonstration, it is determined that the historical flood peak level and flow rate of this river reach the peak flow basically consistent with this survey and analysis.
