The coordinating model of the ganga basin

A scheme of model studies required to analyse a complex large scale system through decomposition approach is outlined. First, the total system is proposed to be modelled to identify interlinkages of the subsystems. Then the subsystems are analysed in detail to develop response functions. Finally the optimal system functioning is obtained by modelling the entire system in terms of response functions of the components.A linear programming model is developed for modelling the total system to identify the interlinkages. Its application is demonstrated in the Greater Ganga Basin using published data. Trade-off is developed between power generation and irrigated area in various seasons.
