4.7.4 Study for Riverflow Data

Riverflow data of the BRS was collected and used for developing discharge-duration curves.

The status of riverflow data for each gauging station is shown below. Riverflow gauging

stations with short records (less than 4 or 5 years) are excluded from this study. Riverflow

data from stations where riverflow records differ in character from other stations in the same

water resource region, or where riverflow data is extremely large / small is also excluded

from target data.

4.7.5 Discharge-Duration Curves

As described above, applicable riverflow records are used for developing discharge-duration

curves. By comparing discharge-duration curves with other riverflow gauging stations in the

WRR (Water Recourses Region), riverflow data from stations where riverflow records differ

in character from other stations in the water resource regions, or where riverflow data is too

large / small is excluded from target data. For zoning segmentation areas of discharge –

duration curves, the following points are taken into considerations: (1) Characteristics of

discharge-duration curves, (2) Climate Regions and (3) Annual Rainfall Distributions. The

methodology for developing discharge-duration curves for each zone and the results of zoning

are shown below. As a result of this study, discharge-duration curves and their zones are

shown in Fig. 4.7-7 and Table 4.7-5.
