Application of physically-based and experimentally calibrated method for flood hazard assessment: Case study of Zaio, Morocco

Abstract

This study aims to assess the urban flood hazard in Zaio, Morocco by utilizing a rainfall-runoff transformation and hydrodynamic modelling. We utilized a statistical adjustment and The Soil Conservation Service–Curve Number (SCS-CN) method to estimate the 100-year return period flood hydrograph, which itself served as input for the Iber numerical model. Flood hazard assessment for human adults was calculated using a physically-based and experimentally calibrated method, a method that takes into consideration all physical forces acting on a human body during a flood, i.e., drag and buoyancy, and thereby facilitate a more precise assessment of urban flood hazard.
