If we describe the system by using mathematical concepts and language, then the process is called mathematical modelling. Or we can say we use the mathematical expression to describe a real quantitative situation. By the mathematical model, we can represent in mathematical terms of the behaviour of real devices and objects. Numerical modelling: Numerical models are mathematical models that use some sort of numerical time-stepping procedure to obtain the models behaviour over time. Numerical modelling uses mathematical models to describe the physical conditions of geological scenarios using numbers and equations.
