of that added by the Chao Phraya River while DIN and SiO2 are each about 40% of the river input. The dissolved organic nutrients are also substantial with seepage inputs equivalent to about 30% of the river for DON and DOC and 130% for DOP. The results for the wet season show greater seepage fluxes although less impact relative to the Chao Phraya
because the river discharge (and thus nutrient flux) is also much higher at that time. In spite of that, the estimated seepage flux for DIN, PO4, and SiO2 are still significant at roughly 20%, 60%, and 15% of that of the Chao Phraya River, respectively. Relative inputs of DON at 40% are similar to that of the dry season while both the DOP and DOC are
relatively lower at 30% and 20% of the river input
