“…The capability of the runoff models in the above evaluation without direct involvement of rainfall characteristics in estimation of sediment associated OM and P agreed with the findings of Williams and Berndt (1977), Hrissanthou (2005), and Noor et al (2010, 2011) who stated that sediment and nutrient yield from upland areas is generally better correlated with observed runoff than with rainfall, although a longer and more widespread record of data is needed to better define the natural condition. The results of the present study can facilitate better understanding of the conditions in the Hyrcanian area, northern Iran, though more elaborated and comprehensive studies are essential for obtaining reliable conclusion in the future.…”

Noor H., Fazli S., Alibakhshi S.M. (2013) Suspended sediment (SS) resulted from distributed soil erosions facilitates soil organic matter and phosphorus (P) transportation and influences soil depletion and water quality. Organic matter (OM) in soil is the most important indicator of soil quality and productivity. P is one of the major nutrients controlling eutrophication of surface water. Irregular contaminant load pulsed by heavy rainfall may damage the ecological quality of downstream waters. Evaluation of OM and P, depleted by erosion processes in watershed scale, is necessary for better understanding the watershed system and should lead to appropriate management approaches. On the other hand, different behaviours of soil erosion as well as the necessity of regional studies have been proved. The present study was conducted in the Kojour watershed, Iran in order to (1) get some ideas about the storm-wise OM and P load in river, (2) evaluate the relationship between the peak of OM and P concentration and discharge during individual rainfall events, and (3) assess the applicability of rainfall and runoff variables of ten storm events in the prediction of storm-wise OM and P loss. The results showed that most of the OM and P peaks preceded the peak discharge, following a clockwise hysteretic loop that exhibited hysteresis with a greater OM and P concentration for a given discharge occurring on the rising limb rather than on the falling limb. The results also showed that regression models had good efficiency in estimation of storm-wise OM and P loss with coefficient of determination of 0.96 and 0.93, respectively.

“…An improved erosivity factor was therefore introduced by Williams (1975Williams ( , 1977 and Foster et al (1977) to also take into account the runoff shear stress effect in terms of the product of runoff volume and peak discharge, on soil detachment for single storms. The approach of Williams and Berndt (1977) in developing a modified version of the USLE was to derive a sediment yield estimation model based on runoff characteristics as the best single indicator for storm-event sediment yield prediction at the watershed outlet (Williams 1975, Beasley et al 1980, Sadeghi and Mahdavi 2004, Hrissanthou 2005, Mishra et al 2006, Sadeghi et al 2007a, 2007b, Mishra and Ravibabu 2009) and some factors affecting soil erosion. Williams (1975) showed that the estimate of stream sediment yield for individual storms could be simplified by using the USLE with its rainfall factor (R) replaced by a runoff factor.…”

The sediment yield model of the MUSLE (modified universal soil loss equation) is applied extensively throughout the world, but different performances have been reported of its success relative to measured data. A review of all the available literature is presented to assess the application of the model under different conditions and, ultimately, make a comprehensive judgement on the different aspects to allow readers to adjust their further research. A review of 49 papers showed the variable accuracy of the model, which depends on the manner of calculation and determination of the input and output, and the study time and space scales. There were differences in land use, in correspondence of the physiographic characteristics with those of the original conditions of model development, and even in the experience of researchers in applying the model. The results also show the need to consider the original application of the model, as proposed by its developers, to achieve comparable results.

“…In previous publications of the second author, different versions of the present model were used (Hrissanthou 2002(Hrissanthou , 2005. The main differences between the previous model versions and the present model version are summarized below: (a) The time variation of stream discharge and sediment discharge, on a hourly time basis, at the basin outlet is computed in the present model version.…”

“…In the previous studies, sediment yield values at the basin outlet were not available. (e) The previous model versions were applied to Nestos River basin, downstream of Platanovrysi Dam, with an area of 838 km 2 (Hrissanthou 2002) and to Kompsatos River basin with an area of 567 km 2 (Hrissanthou 2005). Both basins are neighbouring to Kosynthos River basin, with an area of 237 km 2 , considered in the present study.…”

The aim of this study is to present continuous simulation efforts of soil and streambed erosion processes, as well as the comparison of computed sediment load values with field measurements. For this reason, a composite mathematical model, consisting of three submodels, is applied to the basin of Kosynthos River (district of Xanthi, Thrace, northeastern Greece): a rainfall-runoff submodel, a soil erosion submodel and a sediment transport submodel for streams. The rainfall-runoff submodel that is used for the computation of the surface runoff and the streamflow in the sub-basins, is the deterministic distributed hydrologic model HEC-HMS 3.5. For the estimate of soil erosion in a sub-basin, the model of Poesen (1985) is used, while for the estimate of sediment yield at the outlet of a sub-basin, and finally at the outlet of the whole basin, the stream sediment transport model of Yang and Stall (1976) is used. The statistic efficiency criteria utilized for the comparison between computed and measured sediment discharge values at the outlet of the whole basin, provide satisfactory values. Therefore, it is concluded that the continuous hydromorphologic modeling can be successfully applied to Kosynthos River basin.
