This paper tries to systematically survey, with taking theoretical view on geomorphic basin and its changes into account. The purpose of this research is to determine the balance and stability of geomorphic basins from the past to present and then to future. Consequently, it tries to determine the balance between energy and input-output materials for example (rainfall , solar radiation, tectonics and neotectonics …) to the basin based cybernetics (including geomorphic, topographic and geological state) and also to calculate energy and material balance considering positive and negative entropy at basin level. Based on the findings, which is the outcome of cybernetic resultant between form and process in basin, we can determine stability and type of balance in the basin. In this paper, emphasis has been put only on rainfall (express of the energy exponent). However, it first discusses Kor Basin Geomorphic locations and Energy-Material Entropy on its surface and then Quantity form of energy (Isolated & Potential Energy). Considering geomorphic state of the basin, we can determine the best planning method from all systems (planning, risk management and crisis management) for basin that neither requires a great cost nor causes disturbance in stability and geomorphic balance while being the optimal process. In Kor geo planning, we are encountering and determining two dimentions: (Y dimension, for geomorphic change for example throughput topogeraphy geradient formations on Kor Basin and X dimension, for rainfall discharge range on Kor Basin rivers out let only and only on fiat paper surface), but in Kor geo management, we represent at least three – dimensional ordered, for example topogeraphy gradient for Y coordinate and rivers discharge quantity for X coordinate and absolution geography location (for space point Z coordinate). Consequently, Kor River Basin can be studied based on two scientific metod : I . Planning & II , Management .
