Assessment of Risks of Flooding by Use of a Two-Dimensional Modelby A. Paquier,
Abstract: In case of rare floods, the rivers might go far away from their minor bed, submerging large areas, eventually with relatively high velocities. One-dimensional models are not suitable to describe such events as cross velocities are often of same order as velocities in the axis of the minor bed. With the support of the example of the flooding of a coastal plain (Agly River) in Southern France, we describe the use of a two-dimensional model in such cases.
