MODELLING OF THE RIPARIAN VEGETATION DYNAMICS DUE TO RESERVOIR OPERATIONS THROUGH AN INTEGRATED CELLULAR AUTOMATA
Riparian zones are important to the interception of diffusive pollutants and the rehabilitation of aquatic ecosystems. Due to the high fluctuations of the river flows, riparian ecosystems usually have strong dynamic behaviours. This paper focuses on the understanding of the vegetation dynamics and successions of riparian zones of compound channels when the flow regimes are fundamentally modified by river regulations such as reservoir operations. The paper developed an integrated riparian vegetation model which couples the global continuum formulations of hydrodynamics with the local cellular automata of vegetation evolution. The model was then applied to a compound channel of the Lijiang River in the Southwest China, which has been affected by the flow regulations for navigation purpose. Through the simulations, the previous changes of the riparian vegetations were analyzed and their future developments under the new flow regulation scheme were predicted. In particular, the potentials of integrating global formulation and cellular automata were well studied.
