Σύνοψη	The Mechanistic-Empirical Pavement Design Guide (MEPDG or Pavement ME) is a modern method for designing asphalt pavements that predicts performance (rutting, cracking) using mechanistic stress analysis combined with empirical distress models. Developed by AASHTO in 2008 as a successor to the 1993 AASHTO Empirical Guide, this approach provides better accuracy and enables climate-based, site-specific design.	The unit hydrograph (UH) is a linear transformation that converts rainfall excess into streamflow for a watershed. Introduced by Sherman in 1932, the UH assumes that rainfall-runoff response is linear and time-invariant, enabling synthesis of flood hydrographs from design storms for dam spillway design and flood risk assessment.
