Maximum currents are reported in the Mazatlan port area. Secretaría de Marina report a maximum current within the port of Mazatlan of about 0:7ms1, and Montano-Ley et al.observe a maximum current of 0:6ms1 in the main channel,which acts as a natural conduit flow due to its depth and location . Montano-Ley et al.
report a significant current decrease in the upper UCL to 0:3ms1, very close to the simulated value and attributed to bottom friction in the shallow upper lagoon.
