  1. The theory of minimum entropy production or minimum rate of energy dissipation shows that a river is stable when it is in a relative equilibrium condition. ( 3 ) the river facies formulas of alluvial river have been developed using the theory of minimum rate of energy dissipation together with flow continuity and motion equations, suspended load transport or bed load transport equation. ( 4 ) the causes of the river patterns are explained using the theory of minimum rate of energy dissipation

    ( 3 )基於最小能耗率原理,以水流能耗率作為目標函數,以水流連續方程、水流運動方程及懸移質挾沙力公式或推移質輸沙率公式作為約束條件,通過對目標函數求條件極值,分別推導出以懸移質造床為主的顯式河相關系式和以推移質造床為主的顯式河相關系式。
  2. Basic equation for variation of bed material composition in active layer of alluvial river
