-
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.
