Flood risk index assessment in Johor river basin [Penilaian indeks risiko banjir di lembangan sungai Johor]
This study is focusing on constructing the flood risk index in the Johor river basin. The application of statistical methods such as factor analysis (FA), statistical process control (SPC) and artificial neural network (ANN) had revealed the most efficient flood risk index. The result in FA was wate...
