amir kabir dam was built in varian strait, at 23 km north of karaj in 1961. the dam is multipurpose and its maim aims are the spring floods control, supplying potable water for tehran city, producing electricity and providing irrigation water. different pollutants which discharge to the river finally enter to the dam reservoir. determining the pollution loads of the dam sub-catchments can help ...

In developing TMDL waste-load allocations for the Snake River-Reservoir system in Western Idaho and Eastern Oregon, determinations of the assimilative capacity of the system and the impact of pollutant reduction strategies has been performed using both a statistical-correlation approach and a mechanistic modeling approach. The system included the Lower Snake River, Brownlee Reservoir, Oxbow Res...

In 2015 the Gunungrowo Reservoir was dredged to reduce sedimentation. After dredging, it is necessary carry out sedimentation analysis determine reservoir life be achieved. This intended evaluate sediment deposition patterns that have occurred up and calculate can achieved after dredging in 2015. The analyzed based on how long dead storage has been filled with sediment. Sediment entering calcul...

The Study of river water quality interation with lakes and dam reservoirs is important from anexploitation point of view. When river water with different densities enters a lake or dam reservoir,underflow density current phenomenon occurs. Because of the density, so understandingdifferent arrays of this phenomenon Seems necessary for checking erosion and sedimentationprocesses and their managem...

Estimating the environmental exposure to manufactured nanomaterials is part of risk assessment. Because nanoparticles aggregate with each other (homoaggregation) and with other particles (heteroaggregation), the main route of the removal of most nanoparticles from water is aggregation, followed by sedimentation. The authors used water samples from two rivers in Europe, the Rhine and the Meuse. ...

Estimation of sediment transport load due to erosion in river basins is one of the issues which is indispensable for many projects related to water resources, soil and damps construction. With regards to the phenomenon of erosion and transmission Sedimentation in rivers has always led to deformation in the seaboard and sedimentation, so the management and planning in bank of rivers is important...

Abstract The sandy braided river depositional system developed in the Lower Shihezi Formation of Daniudi gas field, Ordos Basin. It has characteristics frequent migration and oscillation channels large well spacing, making it challenging to portray sand body this area, bringing uncertainty 3D geological modeling reservoir. This study takes primary reservoir H1 member as an example. establishes ...

the karkheh dam reservoir with a capacity of more than 5 billion cubic meter is the largest dam in iran with both agricultural and drinking usages. its hydrodynamics and water quality were modeled and simulated to analyze the total maximum daily load (tmdl) of total dissolved solids (tds). the simulation was supported with measurements of temperature and tds measurements during two years. a lat...
