The Response of Hydrological Performance Indicators to Land Uses Change at the Watershed Scale

Negar Tayebzadeh Moghadam; Bahram Malekmohammadi

Volume 77, Issue 1 , April 2024, , Pages 85-105


  The response of water balance components as indicators of hydrological performance to stimuli such as land use change is of strategic importance. In this study, the effect of land use change on water balance components was evaluated, focusing on the relationships and change of the main indicators of ...  Read More

Evaluating the forest harvesting operations impact on sediment yield in forest watershed (Case study: Kheyrud forest)

saeedeh joriz; Meghdad Jourgholami; arash malekian; maryam etehadi

Volume 72, Issue 3 , December 2019, , Pages 665-681


  Land use changes can significantly affect the hydrology of a forest watershed. Ground cover is important to protect the soil against erosion. Timber harvesting has been changed the canopy cover and forest soil was exposed to the wind and water. Soil compaction and removing the forest floor in the skid ...  Read More

Landuse changes detection and evaluation of their effects on simulated discharge and sediment yield using SWAT model (Case Study: Galikesh Watershed, Golestan Province)

ayoub moradi; Ali Nakafinejad; Majid Ownagh; Choghi Bairam Komaki; mehrangiz foladi mansouri

Volume 71, Issue 2 , September 2018, , Pages 489-504


  Indiscriminate land utilization methods, forest and rangeland degradation, land abandonment and development of residential areas contribute to the changes in flow intensity, erosion rate and sedimentation. Therefore, having knowledge on the effect of land use changes on discharge flow and sediment yield ...  Read More

Assessment of Forest Roads Sediment Yield using WARSEM, SEDMODL and Direct Measurement through Rainfall Simulation

Ataollah Kavian; Atta Safari; Aidin Parsakhoo

Volume 69, Issue 1 , June 2016, , Pages 167-186


  In this study, the sediment yield of forest roads of Darabkola watershed was investigated andestimated using WARSEM and SEDMODEL. Rainfall simulator was applied to measure thesediment of abovementioned roads directly. In order to apply WARSEM and SEDMODEL models,field operations for measurement of different ...  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

Study Of Effective Factors On Sediment Yield of Loess Deposits Using Rainfall Simulator

Mohammad Nohtani; Sadat Feiznia; Hasan Ahmadi; Hamidreza Peirovan

Volume 68, Issue 2 , September 2015, , Pages 399-412


  Loess Deposit is one of the most important Quaternary Deposits of northeastern parts of Iran which have high erosion rate. This study was performed with field- Rainfall- Simulator which has a plot area of 1 m2 in Gorganrood Drainage Basin to determine the effective factors on sediment yield. Landuse, ...  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

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
