Abstract: 

The aim of present study is analyzing the mechanism of erosion cause and sediment production, its irregular excavation and environmental disadvantage effects on Karganrud River in Gilan province. The research is done by many field studies and by using PSIAC method the numerical factor of catchment's erosion has been achieved. Besides by using relative mathematical equations of annual river discharge, the annual sediment weight of Karganrud River has been calculated. The achieved results can be used for a proper river alluvial excavation program by conserving the environmental resources. Mean while by observing the satellite pictures in different years, some parts of river have been widen abnormally which is due to the irregular alluvial excavation by beneficiary factories. The field studies show this phenomena cause disaster around the river sides and lands. However due to the irregular alluvial excavation the river hydraulic gradient has been increased sharply and all meanders have been wash out. Increment of river hydraulic gradient and decreasing the number of local fishes and their spawning which are important environmental disasters.
