Flood prevention managers base decisions and policies - along with other matters - on river forecast systems and identified risks. Most assessment programs however do not address the geotechnical levee failure mechanisms. The REAL™ (Rapid Engineering Assessment of Levees) method incorporates the levee's geotechnical failure mechanisms to get a clear view on levee safety risks and thus improving flood risk management. REAL™ is based on the repetitive character of the evaluations for large stretches of levees and the need to perform these assessments, both efficiently and economically.

REAL™ is a GIS based automated levee assessment method which enables FAST4DMAP® grid analyses and batch processing  (developed by Deltares) of different failure mechanisms using sophisticated algorithms, surface and subsurface models. The models consist of different types of data (LiDAR, HEM, boreholes, CPT's and water levels).

REAL™ enables:

• Systematic consistency in studying the different levee failure mechanisms
• Multi water level analyses, such as high event scenarios
• Quick insight in altered assumptions and insights in physical phenomena
