Modelling of Suspended Sediment Yield and Determination of Effective Factors on sediment variability in Karoon and Karkhe Watersheds

vahid chitsaz; Aliakbar Nazari Samani; Saeed Soltani; sadat feiznia

Volume 73, Issue 2 , September 2020, , Pages 293-303


  Sediment and erosion are two natural phenomena in watersheds. Due to irregular recording and sampling difficulties, daily data are not available for sediment records. Therefore, decision makers and researchers have to apply interpolating methods to estimated sediment yields. In this study, 30 watershed ...  Read More

Investigating condition of karstic lineaments in watersheds leading to Persian Gulf

Mohsen Farzin; Aliakbar Nazari Samani; saeideh menbari; sadat feiznia; gholamabbas kazemi

Volume 73, Issue 1 , June 2020, , Pages 167-181


  This research tries to show the role and importance of karst formations in the infiltration of surface flows and recharge of groundwater resources in the region by determining the lineaments of geological formations in watersheds leading to the Persian Gulf and explaining the relative contribution of ...  Read More

Investigation of sediment sources of Drainage Basin by fingerprinting Method

Sadat Feiznia; Asghar Kouhpeima; Hasan Ahmadi; Ali Asghar Hashemi

Volume 66, Issue 2 , July 2013, , Pages 299-306


  Due to successes of fingerprinting method in producing rapid and low-cost information of sediment sources, in this research this method was used in three sub-cathments of Chasht-Khoran Basin in Semnan Province: Amrovan, Atari and Ali-Abad. Samples below 63 μm were separated and 15 fingerprinting propertis ...  Read More

Sediment yield determination of different geological formations in Gachsaran floodwater spreading field

M. Padyab; S. Feiznia

Volume 65, Issue 4 , March 2013, , Pages 473-482


  Importance of sediment storage has been expressed as being higher than that of water in floodwater spreading networks. To determine the contribution of each geological formation in sediment input of Gachsaran Floodwater Spreading Station after 12 years of flood spreading, sediment sampling was conducted ...  Read More

Assessment of runoff and sediment generation in Neogene's units under rainfall simulator (Case study: Taleghan Basin

S. H. Hosseini; S. Feiznia; H. R. Peyrovan; Gh. R. Zehtabian

Volume 62, Issue 2 , October 2009, , Pages 215-228

  In Iran, fine grained formations (Neogene's units) are very susceptible to erosion. Also, they are the units producing runoff and causing soil loss in watersheds. The objectives of this study is to assess the effect of physical - chemical and mechanical properties of these formations on sediment and ...  Read More
