| ABSTRACT
|
| In 1991-1992, collecting and analyse recorded mean monthly and mean annual rainfall and runoff of 60 and 23 stations respectively. First, recorded mean monthly runoff of each 15 selected key stations was simulated in 25 years (1966-1990) by HEC-4 Monthly streamflow simulation programme. |
| Bang Pakong River Basin is divided into 8 sub-basins. Four regression equations (Qm = aAb) for the relationship between mean runoff (Qm) and drainage area (A) of sub-basins are analysed. Then mean monthly and mean annual runoff for each sub-basins and whole basin are estimated by these regression equations. Finally, the result of mean monthly runoff and mean annual runoff are presented. Four regression equations are also estimated annual runoff for ungaged basins of Ban Pakong River Basin. |
