Empirical flood formula

  "id": "MLC-T-MET-005363",
  "term": "Empirical flood formula",
  "field": "Meteorology and atmospheric science",
  "definition": "A mathematical equation used to estimate the peak discharge of a flood based on observed relationships between rainfall, catchment characteristics, and historical runoff data. These formulas, such as the Rational Method (Q=CIA), rely on easily measured parameters like drainage area, land cover, and rainfall intensity rather than a full physical simulation of hydrological processes. They are most applicable to small, ungauged watersheds where detailed data for complex models is unavailable.",
