Comparison of Spatial Variations of Soil Erosion at Gonbad Representative and Treated Watersheds in Hamadan Province

Seyed Hamidreza Sadeghi; Zahra Hashemi Ariyan; Mehdi Vafakhah; Zeinab Karimi

Volume 71, Issue 2 , September 2018, , Pages 405-417


  Studying temporal and spatial variations of soil erosion and the effective factors is very important for providing appropriate solutions to properly plan the utilization of watershed resources. However, few studies have attempted to examine temporal and spatial variations of soil erosion. In this study, ...  Read More

Effect of Data Length, Study Span and Number of Stations on Amount of Rainfall Erosivity Factor Variability in Different Time Scales in Iran

Seyed Hamid Reza Sadeghi; Mohsen Zabihi; Mehdi Vafakh

Volume 70, Issue 2 , August 2017, , Pages 399-409


  Regarding the undeniable role of rainfall erositivity factor in initiating water erosion, studying its different aspects is important in optimal soil and water resources management. It is taken in to account in many soil erosion estimation models which are used for soil and water conservation. However, ...  Read More

Dynamics of Sediment Hysteresis Patterns during Storm Events

Pari Saeidi; Seyed Hamidreza Sadeghi; Abdoulrasoul Telvari

Volume 70, Issue 1 , June 2017, , Pages 125-138


  Understanding and quantifying the dynamics of suspended sediment transport is essential to control soil erosion and implement appropriate mitigation practices to reduce stream suspendedsediment and on-site and off-site effects of sediment transport. However, the quantification and the interpretation ...  Read More

Evaluation of Time-Area Accuracy in Developing IUH

Hamid Reza Moradi; Hanieh Asadi; Seyed Hamidreza Sadeghi; Abdolrasool Telvari

Volume 68, Issue 3 , October 2015, , Pages 647-656


  The hydrograph at watershed outlet can be expressed as hydrological response of watershed to geomorphological behavior. In present study with the aid of the GIS and the concept of instantaneous unit hydrograph, the watershed response was simulated. In present physical method, the IUH is derived from ...  Read More

Analysis of Intra-Storm Suspended Sediment Delivery Processes from Different Tributaries to the Lake Zarivar using Hysteresis Patterns

Seyed Hamidreza Sadeghi; Shirkouh Ebrahimi Mohammadi; Kamran Chapi

Volume 68, Issue 2 , September 2015, , Pages 323-340


  The behavior of suspended sediment during flood events is not only a function of energy conditions, i.e. sediment is stored at low flow and transported under high flow conditions, but also is related to the variations in sediment supply and sediment depletion. These changes in sediment availability result ...  Read More

Developing Models of Daily Sediment Yield Estimation for Kojur Forest Watershed

Zakariya Asadolahi; Mahdi Vafakhah; Seyed Hamidreza Sadeghi

Volume 67, Issue 1 , May 2014, , Pages 1-15


  Todays, dynamic models are supposed as the most important tools in erosion and sediment phenomenadue to their complexities and existence of many affecting factors. Towards, the present study wasconducted in the Kojour watershed for daily sediment modeling using daily rainfall, discharge andsediment during ...  Read More
