  1. Flash Flood Simulation over Egyptusing RegCM3 Dr. H. Hasanean Abdel Tawab Shalaby Bakr A.M. Badawy

  2. Objective • The aim of the work to simulate the flash flood of November 1-2,1994, and study the ability of the RegCM3 to describe the sever mesoscale process responsible for development of the unusually intensive Storm of November 1-2, 1994

  3. Model Setup • Domain Area: • (20° W to 45° E & 15° S to 40° N) cover EgyptArea • Case Study: • Flash Flood Event ( 1,2 November 1994 ) • Two Simulations:, • 40 km Resolution • 60 Km Resolution • Different Convective and Cumulus Schemes: • Arakawa-Schubert & Anthes-Kuo • Arakawa-Schubert & Scheme Grell • Fritsch-Chappell & Anthes-Kuo • Fritsch-Chappell & Scheme Grell
