Target entity: modified Meyer-Peter–Müller formula
Context triple: [Meyer-Peter–Müller bed-load formula, hasVariant, modified Meyer-Peter–Müller formula]
  • A. Meyer-Peter–Müller bed-load formula chosen
    The Meyer-Peter–Müller bed-load formula is a classic empirical equation in fluvial hydraulics used to estimate the transport rate of coarse sediment along a riverbed under given flow conditions.
  • B. Einstein bed-load function
    The Einstein bed-load function is a seminal hydraulic engineering formula developed by Hans Albert Einstein to predict the transport rate of sediment particles rolling and sliding along a riverbed under flowing water.
  • C. Darcy’s law
    Darcy’s law is a fundamental equation in fluid mechanics that relates the volumetric flow rate of a fluid through a porous medium to the pressure gradient, permeability, and fluid viscosity.
  • D. Kimura two-parameter model
    The Kimura two-parameter model is a foundational mathematical model in molecular evolution that describes DNA sequence change by distinguishing between transition and transversion substitution rates.
  • E. Froude number
    The Froude number is a dimensionless quantity in fluid dynamics that compares inertial forces to gravitational forces, commonly used to characterize flow regimes in open channels and around ships.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
