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

  Land cover is also important factor for protecting the soil against erosion. A fully forested watershed experiences relatively little surface erosion, but timber harvest alters the canopy cover, exposing the soil to water and wind. Forests provide the maximum amount of soil protection. Reduction of vegetative ...  Read More

Evaluation of the effect of forest cover on quantitative and qualitative runoff parameters in Chitgar Forest Park Watershed, Tehran

Volume 71, Issue 4 , March 2019, , Pages 997-1011


  Many environmental challenges such as stormwater runoff and flood risk, chemical and particulate pollution of urban air, soil and water, the urban heat island, and summer heat waves are exacerbated in urban environments. Runoff from heavy rainfall in many parts of the world lead to erosion, sedimentation ...  Read More

Daily Rainfall Temporal Distribution Patterns and its Relations with Short-Term Precipitations in Coastal – Forest Areas (Case Study: Nowshahr Station, Northern Iran)

Maryam Moradnezhadi; Arash Malekian; Meghdad Jourgholami; Ali Ghasemi

Volume 69, Issue 2 , July 2016, , Pages 475-485


  24 hour precipitation distribution pattern and its relationship to short-term rainfall is an important issue in hydrology studies such as in flood simulation and in design of hydraulic structures. Accordingly, this study made an attempt to investigate the relationship between daily precipitation and ...  Read More

Effects of forest harvesting operations on physical properties and soil penetration resistance (Case study: Kheyrud forest)

Meghdad Jourgholami; Vahid Rizvandi; Baris Majnounian Garagiz

Volume 66, Issue 2 , July 2013, , Pages 223-236


  Assessment and management of the environmental impacts of forest harvesting operations have become increasingly critical factors in practicing commercial forestry. This study investigated soil disturbance from a forest logging system operation on an 8-hectare mixed broadleaved stand in compartment no. ...  Read More
