Abstract:Abstract: Hydrological archives are an important part of hydrological work. Faced with the new situation and new requirements of hydrological management, the construction of hydrological archives informatization needs to be strengthened urgently. Taking Suzhou hydrology as an example, based on the current situation of Suzhou hydrological archives management, this paper discusses the basic level hydrology in view of the weak awareness of archives and the low degree of attention paid to it. Challenges and corresponding measures faced by units in hardware, digitalization, system, personnel and other aspects of archives information construction work provide reference for the development of basic-level hydrological archives work.
