Abstract

Awareness of transported sediments and its temporal variation increase the precision of soil and water conservation projects and is an important indicator for determination of organic matter (OM) loss. Therefore, establishing the relationship between suspended sediment and OM content has a vital role in watershed management. Therefore, the present study was conducted in Educational and Research Watershed of Tarbiat Modares University (Kojour) with an area of 50130 ha to investigate temporal variation of OM and suspended sediment (SS) relationship in seasonal, monthly and storm scales for data set collected during autumn 2007 and spring 2008. For this purpose, water and SS samplings were made via depth-integration method and samples were then transported to the lab. SS was separated via decantation method. OM amount was also determined with loss on ignition procedure. The relationship between OM and SS in different time scales was evaluated by using different BIVARIATE REGRESSION methods. Results of this study verified a high correlation between SS and OM in fall and winter seasons and December and January with respective correlation coefficients of some 0.90, 0.86, 0.95 and 0.95 (P<0.01), estimation and validation errors less than 37.18 and 36.90 and coefficient of efficiency more than 0.41. Whereas no significant relationship could be attained for spring and February, April and May, in evidence of small value of SS.
