Abstract

Todays, dynamic models are supposed as the most important tools in erosion and sediment phenomena due to their complexities and existence of many affecting factors. Towards, the present study was conducted in the Kojour watershed for daily sediment modeling using daily rainfall, discharge and sediment during 2007 to 2010. The modeling process was carried out all data and the monthly and seasonally classification data in linear and nonlinear models. The results indicated that daily linear and non-linear models did not indicate a suitable model. The monthly and seasonally classification of the data led to achievement of better models with determination coefficient significant at 5 percent level and relative error less than 40 percent as compared with those obtained from no classification. It was also found out that daily sediment of Kojour watershed was affected by discharge occurred event day and before four days. The discharge occurred event day is the most effective factor in 80% selected models in the study watershed. The nonlinear models were better estimation than linear models in July, September, December and March and autumn but linear models were better than nonlinear models in other months and seasons.
