Variabilities in Johor river discharge

Variabilities in Johor river discharge

River discharge is the volume of water which flows through a river channel within a specific time. Discharges are normally used by the hydrologist in order to measure variability of a flow. The aim of this study is to compare the variability of different period of hydrological time series discharge...
