ملخص المقالة :
Sedimentation in the Tank’s dam is complicated phenomenon and If we don’t have any information about sediment transport and control method, It cause decrease duration of use dam and waste of huge popular wealth. Thesis goal is study on Estimate particles and Investigation and of tank`s sediment in olya Gotvand dam by using of CCHE2D software. To run this model use many base data like upstream river cross section specification, daily discharge statistics and air temperature, river discharge, varied reversion of flood water, river bed grain size and other need information’s. After insert all need data and run this model, the load sediment import in olia Gotvand dam`s tank is equal 89435 million cube meter per year and according to this result, after 100 year the sedimentation in order to trap coefficient 90 %, the whole sediment logs are jammed in the dam`s tank is equal 241 million cube meter and consequently this sediment to be formed 7.23% total volume of this dam`s tank. Most of Sediment Transport is kind of large silt with size 0.031-0.0625 mm and very small sand with size 0.0625-0.125.
