| Monthly variations of physico-chemical and biological parameter were determined in near the Kum River mouth at lower discharge period from January 1998 to September 1999. The characteristics of water quality was showed hypertrophic with average values of total nitrogen (TN), total phosphorus (TP), chlorophyll-a and transparency are 3.9 mg N/l, $160;{mu}g/l$, $73;{mu}g/l$ and 0.8 m, respectively. Among a nitrogen component, inorganic and organic nitrogen comprised 34% and 66% of TN, $NH_4$ and $NO_3$ comprised 30% and 70% of inorganic nitrogen respectively. SRP concentration comprised below 9% of TP. TN/TP and DIN/SRP ratio in winter were higher than in summer. SRSi fluctuation was very wide as ranged from 0 to 3.0 mg Si/l and the highest after flood event in summer. Long-term depleted pattern of Si was observed, that is considered to be important nutrient for algal growth. Chlorophyll-a concentration was very high as $113;{mu}g/l$, $162;{mu}g/l$ in winter and summer respectively, which persisent bloomed diatom Stephanodiscus and blue-green algae Microcystis. In consequence, water quality management of these periods are considered very important. |
