eview and handling process is necessary for
all data, with outlier determination rules and
treatment procedures and methods determined
in advance. Fig. 43 illustrates the general quality
control procedures, data management method
for time-series hydrological data, which were
applied to the Geum River system.
To build the quality control system for the Geum
River area in 2009, the research committee
assessed the quality control status of the Geum
River Flood Control Center, and analyzed the
function and status of the data management
system in use. The committee determined a
quality control method for water flux volume data
with rainfall volume and water level data, which

was then used to modify/complement the quality
control system.
To enhance the viability of the quality control
task, the committee encouraged on-demand
education for the staff in charge, and suggested
a modification/supplementation method and
improvement plan for the system and standard
inspection based on evaluations of the system’s
operation results. By establishing guidelines for
daily quality control tasks, the committee put
forth a framework for systematization. It also
facilitated continued adjustments to the system
by proposing a sustainable management plan to
ensure superior hydrological data quality.
