Lund-CIRP Transport Equations

Camenen and Larson (2005, 2007, and 2008) developed a general sediment transport formula for bed and suspended load under combined waves and currents.

Bed load

The current-related bed load transport with wave stirring is given by

  (1)

Suspended load

The current-related suspended load transport with wave stirring is given by

  Failed to parse (unknown function "\eps"): {\displaystyle \frac{q_{s}}{\sqrt{(s-1)gd^3}} = U c_R \frac{\eps}{\w_s} \biggl[ \biggr] } (2)

Failed to parse (unknown function "\eps"): {\displaystyle 1 - \exp{ \biggl( - \frac{w_s d}{\eps}} \biggr) }
