Identification of critical sediment source areas across the Gharesou watershed, Northeastern Iran, using hydrological modeling
In this study, the process-based watershed model, Soil and Water Assessment Tool (SWAT), was used for simulating hydrology and sediment transport in the Gharesou watershed and for identifying critical areas of soil erosion and water pollution. After model calibration and uncertainty analysis using SUFI-2 (Sequential Uncertainty Fitting, ver. 2) method, the outputs of the calibrated model were u...

متن کاملSource Fingerprinting of Sediment Deposited in the Dam Reservoir: A Case of Lavar Dam Watershed, Fin, Hormozgan Province
Extended abstract 1. Introduction Soil erosion is a major environmental threat worldwide. This three-stage process including detachment, transportation and sedimentation of soil particle by runoff affects natural and agricultural areas of Iran. Soil erosion has many off-site and on-site effects such as sediment deposition in the lake of dam and channels, transportation of nutrients and contam...
متن کاملSedimentology of the of Zayandeh-Rood River alluvial Terraces and the sediment source identification
In this research, three alluvial Terraces that are located in pathway of Zayandeh-Rood River are studied. The river starts from Bakhtiayri Zardkoh mountain and after through Esfahan city ends to Gawkhony lake. Age of alluvial terraces is younger in upstream than downstream and the height level of the terraces decrease relative to current river bed toward the downstream. The terraces were sample...
متن کاملIdentification of Critical Sediment Source Areas at Regional Scale for Environmental Management (Case Study: Dehnamak Basin, Iran)
To identify critical sediment sources in large catchments, using easily available terrain information at a regionalscale, a methodology was developed to obtain a qualitative assessment necessary for environmental management.Fargas et al method was employed in the research. The study was carried out in one of the sub-basins of Hableh Roodbasin called Dehnamak in the arid and semiarid climate of ...
