桥涵水文主要是依据河流和水文环境等各项因素进行桥梁设计，是桥位环境设计的一项重要基础工作。通过梳理近些年来桥涵水文的发展状况,从桥涵水文中的一些关键问题——桥涵水文研究方法、设计洪水流量、桥梁基础冲刷的成因、影响因素和桥梁墩台冲刷深度的计算等方面阐述桥梁水文的发展成就，对当前的研究难点和未来的研究热点进行了简要的概括。

Hydrology for bridges and culverts is mainly based on the river and hydrological environment and other factors for bridge design, which is an important basic work of bridge site environmental design. By reviewing the development of hydrology for bridges and culverts in recent years, some key issues from hydrology of bridges and culverts, such as research methods, design flood discharge, causes of bridge foundation scour and influencing factors, and calculation of the scour depth of bridge piers and abutments, elaborated the development achievements of hydrology for bridges and culverts and briefly summarized the current difficulties and future hotspots.
