Application of Two-Dimensional Hydraulic Modelling of Hydrological Risk Related to Urban Flood. A Case of the Taza City, Morocco

Abstract

Flood Risk modelling and analysis have received plenty attention globally because of the growing rate of flood failures in maximum riverine regions. This work aims to map the flood hazard in an urban environment through two-dimensional (2D) modelling with the Iber software. The study area is the city of Taza, located between the Pre Rif and the Middle Atlas in the northeast of Morocco. The inputs to the 2D model are metrological, hydrological, topographical and geological data. The hazard map is developed using 2D hydraulic modelling. The results obtained show that the propagation of rainwater occurs rapidly due to the rugged terrain of the region studied and the impermeability of the soil.
