Transformation of urban flood modelling from hydrodynamic to system dynamics approach

Flood problem is one of the key issues in the urban water management practice. Currently, there is a gap between flood prediction techniques, which mostly by Hydrologic Modelling, and the water management modelling, which mostly use the System Dynamic approach. This paper evaluates the possibility of the integration of hydrodynamic modelling to System Dynamics, which is one of the most common method to develop an urban water modelling. By integrating hydrodynamic modelling within a larger system dynamics-based urban water modelling, the hazard aspect of urban water management can thoroughly be examined. In this paper, the integration of Hydrodynamic Modelling into system dynamics-based urban water modelling is achieved by implementing the flow inputs of hydrodynamic modelling as a variable in the system dynamics.
