There is certain orientation in the development of the fluvial geography, because the process is controlled by the Theory of Minimum Energy Dissipation. According to the theory of entropy and take equilibrium profile of watercourse as example, this paper discussed the theoretical shapes of the fluvial geography after analyzing the mathematics innate character of Theory Minimum Energy Dissipation. Studying result shows that the equilibrium profile of all watercourses should be a cycloid line. Thus point out a new thinking method to the study of the unity of topography in fluvial geography.
