Effects of Sediment on Water Quality in the Wetlands
Journal Title: Journal of River Engineering - Year 2014, Vol 2, Issue 1
Abstract
Flowing water in a stream carries sediment which is considered a pollutant because it interferes with many uses of water. Other pollutants in the water may be attached to or greatly affected by the sediment.One of the causes of high concentrations of dissolved solids in rivers is soil erosion. There are different forms of water erosion in Haraz and Babolrood watersheds. They enter a lot of sediments into the Haraz and Babol rood rivers. These sediments with flows enter into the downstream watersheds of Haraz and Babolrood watersheds. Precipitation changes the water quality and increases the salinization and vegetation. In this study, water quality and vegetation in downstream of Haraz and Babolrood watersheds were compared in different places. The results show that in the vicinity of wetlands water does not have good quality due to upstream sediment accumulation and increased salt water and this has led to changes in vegetation.
