Water Circulation, Sediment Transport, and Pollutant Dynamics in Southern Iberia Waters: A Review on Numerical Modelling Studies

Table 2

Summary of model parameters. In the cases of 𝐸 and the critical stresses for resuspension and deposition, the selected values correspond to intermediate values within their range of variation commonly found in literature. A reference [61] is given as an example. Note that some parameters may differ for the GoC and AS.
