HYDROLOGY ANALYSIS FOR THE JOHOR RIVER USING SYNTHETIC UNIT HYDROGRAPH GAMA I
ABSTRACT: A series of floods
occurred in several places in Malaysia during December 2006 January
2007,including the southern state of Malaysia; Johor Bahru. The rain recorded
in the city of JohorBahru was 286 mm. To understand this phenomenon and to
investigate the design flood of thisregion, a hydrology analysis procedure was
taken into account. The hydrology analysis procedureincludes collecting
rainfall data, analyzing rainfall data including areal rainfall and
rainfallfrequency, developing synthetic unit hydrograph using SUH GAMA I. It is
noticed that the lengthof rainfall data collected, i.e. 60 years, is
sufficiently long for analysis. From the hydrologyanalysis done in this study,
it can be concluded that the rain fell during 2006-2007 flood eventshad nearly 100
years period of rainfall. And the prediction for 100 years period of flood is
16,962m3/s.
