| Summary: | Flood is a major issue during monsoon season in Northern region of Malaysia especially in Muda River Basin. This study focused on the
specific hydrology parameters that lead to the flood events in Muda River Basin, Kedah. There were 4 hydrologic parameters for thirty
years of collected data from selected hydrology monitoring stations provided by Department of Irrigations and Drainage, Malaysia. The
study applied Principal Component Analysis (PCA) and result shown that stream flow and suspended solid stand with highest correlation
of coefficient variables with the changes of water level in the study area. Statistical Process Control (SPC) applied in this study was to
determine the control limit for every selected parameter obtained from PCA. The Upper Control Limit value for water level reported
from SPC analysis in the study area was 7.568m and starting from this level and above, the risk of flood is high to occur in the study
area. This research proved that the flood risk model created in this study was accurate and flexible for flood early warning system at
Muda River Basin. |
