Abstract
This study focused more in flood estimation model for Johor River in Kota Tinggi watershed, Malaysia using HEC-HMS (Hydrological Modeling System). HEC-HMS is necessary tool for analyzing and simulating rainfall and runoff process. In this study, HEC-HMS version 3.5 is used to simulate stream flow for Johor River basin. Calibration and validation process were carried out using different sets of data. Data of precipitation and stream flow used in this study is from the period of January 2012 until December 2012. The precision of data used during calibration and validation process depend on parameter used in HEC-HMS. Results of simulation can be generated in summary table, hydfograph and time series table. Correlation coefficient R 2 and root mean square (RMSE) are used to measure the performance of the modeling. A model with the R2 value is nearly to 1.0 and RMSE value is close to 0 is considered as good and satisfactory. During calibration process, value of RMSE for 1836402 station is 1.9 m3/s while value of RMSE for 1737451 station 1.89 m3/s. During validation process, value of RMSE for 1836402 station is 1.2 m3/s while value of RMSE for 1737451 station is 1.69 m3 Is. The simulated model were fit with the observed data and show that the HEC-HMS are suitable model to predict the hydrologic changes in Johor River.
