Abstract
This study reviews the existing erosion and sediment transport models developed at hillslope and watershed scales. The method followed in this review is to summarize the models with a focus on the physically based modeling technique as well as with a brief discussion about empirical and conceptual models. Approaches for determining the sediment transport capacity of flow are explained. The extension of a sediment transport model to a nutrient transport model is then discussed. Finally, the future of erosion and sediment transport models are projected to include the probabilistic description of hydrology, the physical characteristics of the watershed, and the stochastic structure of soil properties. The review is expected to be of interest to researchers, watershed managers and decision-makers while searching for models to study erosion and sediment transport phenomena and related processes such as pollutant and nutrient transport.

The first author (H. Aksoy) was a post-doctoral researcher with the second author (M.L. Kavvas) when this study was performed at the Hydrologic Research Laboratory, Department of Civil and Environmental Engineering of University of California at Davis (UCDavis). This stay was supported by Istanbul Technical University (ITU) through a postdoctoral research scholarship, by Scientific and Technical Research Council of Turkey (TUBITAK) through NATO B-1 postdoctoral scholarship, and by UCDavis through CA State EPA 205J Grant. The second author's work was supported partially by US EPA Center for Ecological Health Research (Grant No. R819658) at University of California, Davis, and partially by US EPA Grant No. R826282010. However, the views expressed in this paper do not necessarily reflect those of the funding agencies, and no official endorsement should be inferred. The authors also would like to acknowledge constructive comments by two anonymous reviewers, guest editors (Dr. W. Cornelis and Dr. D. Gabriels of Ghent University, Belgium), and editor-in-chief at CATENA at different stages of this manuscript.
