چکیده مقاله:

Every year floods of rivers insert un account of outstanding natural and artificial pollutions in to the earth that it causes irretrievable damages to the environment. From the goal of this study it is inventing new methods of counting pollutions that they cause saltiness at around river grounds on flooding times by applying Hec-Ras software. At first it analyzes data about qualifications and quantities of Ajichay River. Then it classifies data by Hec-Ras software at first syllable by return to 2, 5,10,2550 year periods. At advanced step it verifies bases of floods by salt amounts. The results of study indicated because of wide spread floods at left bank of river there are more Sodium and Colureand also the amount of sodium in floods it is the in highest amount at round fields. Thought these floods insert the most pollution at around fields and it is critical.
