  Background and Objective: Rivers are one of the most important water resources with a wide scopeof applications. On the other hand, any entrance of polluting items into rivers may cause differentphysical and chemical changes. Therefore it is necessary to have a good knowledge of theseparameters and changing process of them. Meanwhile Khersan River is one of the greatest headbranchof Karoon as the most important of State’s rivers. This is due to supplying of major part ofrequired water for civil, rural, agricultural purposes. The present paper intends to specify any physicaland chemical parameters of Khersan River (including Nitrate, Phosphate, Liquid oxygen, BiochemicalOxygen demand, Temperature & pH). It is accompanied with a study of annual changes of it. Sincethere was not a real research on Khersan River with such dimensions, therefore it could be useful inthe field of different applications most of which is dam construction on the concerned river.Method: In order to perform some physical and chemical tests, we performed 12 steps of sampling onmonthly basis. All water samples belonged to 6 stations through the river way. We applied standardsampling method and test procedures.Findings and Discussion: According to the findings, there is maximum rate of water temperaturechanges at concerned stations through July & August. Therefore it may find a reducing process andminimum rate in February as well. pH rate of water was in optimized scope in all stations and throughall months of the year (6.5-9.5 mg/liter). It was at minimum rate at all stations through the September& October. The quantity of liquid oxygen in water was in optimized scope (more than 5 mg/liter) inall stations and all months of the year. Then it may reach to the minimum rate through July & Augustand then to its maximum amount in winters. Biochemical oxygen demand of water had the maximumrate at station No. 1 in the middle of October. Generally we had biochemical oxygen demand morethan permitted maximum rate. The process of nitrate changes in all stations was in optimized scope inall months of the year.Conclusion: Any agricultural activities and distribution of agricultural lands besides this river andalso presence of neighboring villages and civil areas, have great roles in pollution of the river water.

  Rivers are important water resources which to have broad application. Heavy metal are considered as important factors in pollution of water resources. On the other hand, the entry of pollutants into rivers, cause physical and chemical changes in them. The recognition of these metals and the knowledge of their parameters and trends is essential. This study aimed to determine physical and chemical parameters (temperature, pH, dissolved oxygen, EC) and the amount of zinc, nickel and cadmium of  Shatereh river (Its water used to irrigate farm) located in the southwest of Tehran. Sampling was done  at 3 stations in Esfand 1392 (Persian calender before the bridge Shatereh, industrial areas and agricultural areas) with 3 replications.Average ater temperature of 8.25 ° C, mean dissolved oxygen  8.03 , pH levelsranging 8.02 and the average amount were abserved EC 493.32 cm .Average amount of heavy metals, zinc, nickeland cadmium were respectively 0.4206, 38.135, 39.180 micrograms per liter. The variance of zinc, nickel and cadmium of there station at sig <0.05 showed that there was significant difference betwean 3 station. According to the EPA standard of measured parameters, the data are shown t in to be in the acceptable range and the results for zn showed that the levels in all 3 stations are within standard leveland heavy metal content of nickel and cadmium exceeded the standard level at 3 stations.
