Results of numerical experiments with an implementation of  Version 2.3.01 of the Hybrid Coordinate Ocean Model (HYCOM) to the geographical region delimited by 48o–68o E and 23.92o–30.5o N.  Four simulations were done (EXPT012, EXPT013, EXPT014 and EXPT015) forced with atmospheric and radiative products from NCEP Reanalysis. EXPT01.2 did not consider tides nor rivers runoff. EXPT01.3 considered river runoff but no Tides. EXPT01.4 was forced with tides, but no river. EXPT01.5 was forced with both  tids and river runoff.
