Abstract: The primary purpose of this study is to examine, whether or not it is possible to predict sediment characteristics namely total inorganic phosphorus (LSTINP), organic phosphorus (LSTORP) and total iron (LSTFe) from overlying water characteristics, namely total filterable orthophosphate (OVTFO) and total iron (OVTFe) and Pore Water characteristics, namely Total Filterable Orthophosphate (PWTFO) and total iron (PWTFe) in an eutrophic lake where there is no phosphorus release. The calculated determination coefficients, especially 0.588 for autumn 2004 and 0.767 for spring 2005, confirmed that the littoral sediment iron was correlated to overlying water phosphorus and iron. The results also confirmed that an adequate amount of variation in sediment characteristics can be explained by the pore water characteristics owing to the fact that they were statistically significant (p<0.01), except for LSTFe in the spring 2005. The results proved that the measured total filterable phosphorus and total iron concentration of the pore water have a more predictive value for phosphorus concentrations in the littoral sediment of Lake Mogan. In this study, it was also demonstrated that multiple regression equations constructed for one year could not be utilized to predict littoral sediment characteristics effectively in another year.
