INTEGRATING 1D AND 2D HYDRODYNAMIC MODELS FOR FLOOD SIMULATION

FALCONER R. A. / LIN B. / WICKS J. M. / et al. - ARTICLE DE PERIODIQUE - 2006

Presentation of the integration of a two-dimensional (2D) model with the one dimensional hydrodynamic model ISIS to enhance its capability for simulating floodplain flows. The 2D model is based on the DIVAST model, a research model widely used for predicting flows and water quality indicators in estuarine and coastal waters. DIVAST is dynamically linked to the ISIS model and the linked model is used to predict overland flood flows. A serie of numerical test were undertaken. The model was used to predict the flood flow in a urban area.
