“…These methods include physically models, experimental models, and numerical models such as finite difference, finite volume, finite element, and element-free methods. These models involve specific knowledge of the physical characteristics of the study area, complex boundary layers, more assumptions and large dataset which makes it more expensive, labour consuming, tedious etc [ 1 , [10] , [11] , [12] , [13] ]. Nowadays, various machine learning techniques has been proved the capability to overcome the traditional techniques limitations and shown to be precise estimation of different parameters or events with multi time scale in the complex hydrology modelling studies [ [14] , [15] , [16] , [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] ].…”
