Abstract

Systems theoretic approach to modelling rainfall-runoff process with conceptual component S. Sanaga & A. Jain Department of Civil Engineering, Indian Institute of Technology Kanpur, India. Abstract The approaches adopted for rainfall-runoff modelling can be classified into two types: Conceptual and Systems Theoretic. Conceptual models give due consideration to the underlying physical process; whereas, the systems theoretic models do not. In recent years, Artificial Neural Networks (ANNs) have been proposed as efficient tools for modelling and forecasting. Stochastic and ANN models can be classified as systems theoretic models. Researchers have used both conceptual and systems theoretic approaches for rainfall-runoff modelling individually but the attempts to combine the two approaches have been lacking. However, it must be realized that an integrated approach that combines the conceptual and systems theoretic approaches may be able to better represent the rainfall-runoff process. This can be
