Statistical analysis on rainfall and discharge data : in study area in Johor river basin
Johor river is one of the several river that drain into Tebrau Strait ( Selat Tebrau). The Johor river catchment is centered about 35E, 0.5N. Rainfall and flow data for the period 1980 – 2011 were used in this study. The time series of monthly values of rainfall and discharge were analyzed using sta...
