Maleh stream water quality assessment using Prewat Model
In this study, water quality of Maleh stream and its effects on Shadegan wetland water quality were evaluated in various intervals using one-dimensional Prewat model(version 2.4). The Prewat model was developed by the Engineering division of US Army corps. The Maleh stream is located 30 kilometer north of Ahvaz city and is discharged into the Shadegan wetland. To perform the study, water quality parameters from 7 stations were collected during 1387-88. Then the collected data were analyzed and used in the Prewat model. Results of the study indicated a considerable BOD5 removal and a small amount of Nitrogen removal in the stream.
