Fluxes of Dissolved Inorganic Nutrients and Total Suspended Solid at the Sawi River Mouth, Chumphon Province during Wet and Dry Seasons in 2014 – 2015
Abstract
A study on fluxes of dissolved inorganic nutrients and total suspended solid at the Sawi River Mouth, Chumphon Province during wet (9 – 10 September 2014) and dry seasons (28 – 29 April 2015) was conducted. The Acoustic Doppler Current Profiler (ADCP) was used to measure water flux. The results showed that the net fluxes of water, dissolved inorganic ammonia, nitrite, nitrate, phosphate and total suspended solid were directed seaward in wet seasons (1.53 x 106 m3/day, 296.66 kg N/day, 19.61 kg N/day, 659.26 kg N/day, 40.56 kg P/day and 153.93 ton/day, respectively). In dry season, the net fluxes of water, dissolved inorganic ammonia, phosphate and total suspended solid were directed riverward (0.29 x 106 m3/day, 258.13 kg N/day, 4.44 kg P/day and 21.78 ton/day, respectively), and the net fluxes of dissolved inorganic nitrite and nitrate were directed seaward (1.55 kg N/day and 31.48 kg N/day, respectively).
Keywords: Sawi River, fluxes of dissolved inorganic nutrients, fluxes of total suspended solid
