Fourier analysis method can be used as a mathematical tool for modelling the diurnal profile of surface air temperature and surface dissolved oxygen (DO) of lake water. For developing the model, initially Lake Rudrasagar, Tripura, India has been chosen as the study site. Within the scope of this communication, due to availability of collected data the developed mathematical model has been verified for Subhas Sarobar, Kolkata. It is observed that the diurnal profile of DO and surface air temperature of both the lakes studied almost follows similar trends of sinusoidal variation.

Abstract


Fourier analysis method can be used as a mathematical tool for modelling the diurnal profile of surface air temperature and surface dissolved oxygen (DO) of lake water. For developing the model, initially Lake Rudrasagar, Tripura, India has been chosen as the study site. Within the scope of this communication, due to availability of collected data the developed mathematical model has been verified for Subhas Sarobar, Kolkata. It is observed that the diurnal profile of DO and surface air temperature of both the lakes studied almost follows similar trends of sinusoidal variation.
