Ability of Loadest Regression Methods to Estimate Annual Suspended Sediment

Aliakbar Nazari Samani; Aryan Salvati

Volume 74, Issue 3 , December 2021, , Pages 597-609


  Having knowledge on the quantitative amount of watershed sediment yield is one of the most basic information to deal with soil erosion and conservation as well as design of dams. In Iran, the estimation of suspended sediment load is often based on measurement curve methods. Since sediment discharge data ...  Read More

Evaluation of Watershed Plan on the rate of erosion and sediment in Kan basin

golaleh ghaffari; Hassan Ahmadi; Omid Bahmani; Ali akbar Nazari samani

Volume 68, Issue 3 , October 2015, , Pages 607-624


  In Iran due to the lack of long experience in the implementation of Soil Conservation and Watershed Management Plans, these measures have not been evaluated quantitatively and specific methods for this purpose have not been provided. In this research effort is to investigate the effect of watershed management ...  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

Assessing the Impact of input variables preprocessing into support vector machine through gamma test method for suspended sediment volume prediction

Elham Kakaei Lafdani; Ali Reza Moghaddam Nia; Azadeh Ahmadi; Heydar Ebrahimi

Volume 67, Issue 2 , July 2014, , Pages 289-303


  This study aimed to examine the influence of pre-processing input variables by Gamma Test on performance of Support Vector Machine in order to predict the suspended sediment amount of Doiraj River, located in Ilam Province from 1994-2004. The flow discharge and rainfall were considered as the input variables ...  Read More

Estimation of the suspended sediment loud of Karaj River using fuzzy logic and neural networks

A. Salajegheh; A. Fathabadi

Volume 62, Issue 2 , October 2009, , Pages 271-282

  Correct estimation of suspended sediment transported by a river is an important practice in water structure design, environmental problems and water quality issues. Conventionally, sediment rating curve used for suspended sediment estimation in rivers. In this method discharge and sediment discharge ...  Read More
