Abstract

One of the important river in south CASPIAN SEA is Chamkhale river. The Shalmanroud river joien it and compose a estuary system. The aim of this study was measurement of Physico- Chemical factors and fluxes of NUTRIENTS in the estuary. We sampling that factors during a year in five stations from St. 1 (freshwater) to St. 5 (Sea water). Samples taxed from surface and bottom water with hydrobios Rutner. Physical and Chemical factors were, Air and Water temperature, Salinity, pH, Secchi desk transparency and NUTRIENTS were Sio2, No3-, No2, Tp, DIN, Po4, NH4+ and Alkalinity. The important factor in estuaries is salinity and kind of mixing water, Chamkhaleh estuary is a Salt wedge estuary that inters seawater is very different in the seasons. Measurement of physical and chemical factors showed water temperature 19 TOC, Surface salinity 3.95 ppt, bottom salinity 8.45 ppt, pH 8.1, NUTRIENTS concentration was seasonally related to river flow with annual means Sio2 2.648±0.76, No3- 0.434±0.11, No2 0.036±0.025, NH4+ 0.27±0.19, DIN 0.74±0.23, Ort-Po4+ 0.067±0.034, TP 0.114±0.05, Alkalinity 37.4±5.1 mgl-1. Concentration of NUTRIENTS were in station 1 (accept Alkalinity) and minimum level in station 5.NUTRIENTS concentration decreasing from freshwater to sea water. Seasonal fluxes of NUTRIENTS showed that maximum level were in spring (accept Alkalinity).
