About This Course

The Open Learning Course on Flood Hazard and Exposure Mapping is designed to equip participants with the theoretical knowledge and practical skills needed to assess and map flood hazards and exposure using open-source tools such as openLISEM 0.2.5a and QGIS. The course covers fundamental concepts of flood hazards, hydrology, and flooding impacts, along with practical applications of GIS and remote sensing techniques for flood modeling, including the following topics:
  • Introduction to Flood Hazards – Covers the basics of flood hazards, hydrology, and the influence of climate change on flooding.
  • Tools and Techniques for Flood Hazard Mapping – Introduces GIS, remote sensing, flood modeling techniques, and risk assessment methods.
  • Open-Source Flood Modeling Software – Provides hands-on training with openLISEM and QGIS, covering flood simulation, erosion modeling, slope stability, and data processing.
  • Practical Applications and Case Studies – Applies the learned concepts to real-world flood scenarios in Mozambique, including urban, coastal, and riverine flooding.

Sardar Ateeq

Dr.-Ing. Sardar Ateeq is a senior advisor at Antea Group Belgium. He obtained a PhD in Hydraulic and Water Resources Engineering from the Technical University of Munich, Germany, with the highest distinction. He automates 1D/2D/3D hydrodynamic and morphodynamic simulations, significantly reducing project costs and enhancing the precision of engineering designs and numerical calculations. He is actively involved in developing and improving hydrodynamic and morphodynamic simulation tools according to project requirements, utilizing both standard PCs and high-performance computing (HPC). He believes in open science and open-source numerical modeling.

With more than 10 years of experience as a hydraulic engineer, he has performed numerical modeling simulations of flooding and sediment transport on several international projects using his automatic calibration and validation concept. His single-click and play concept reads all inputs, simulates, analyzes, and outputs hazard risk maps automatically.

He uses tools like TELEMAC/GAIA, InfoWorks ICM, MIKE series, HEC-RAS, openLISEM, FLOW-3D, HydroAS, and QGIS, actively contributing to open-source software development.
