การสังเคราะห์ข้อมูลน้ำท่าโดยใช้โปรแกรม HEC-4 (Runoff Generation by HEC-4)

Abstract

HEC-4 is the computer program which used for monthly runoff generation. The
generated runoff data will be used to extend the record to the desired period, which is very
useful for the studied area which has too short record. This program use the statistical
principle - i.e. simple correlation coefficient, normal deviates and random to generate the
data
For the case study at Chi river, the monthly runoff was generated at Ban Thasabeang
station by using 5 stations. The results indicated that the difference between the mean and
standard deviation of the observed runoff and generated runoff were 3% and 2.4%
respectively
