The study of diatoms is necessary because they are the sources of oxygen in rivers, and also constitute the basic primary productivity chain and are used in determining water pollution levels. However, in this study some large rivers of Turkey and Iran were compared in this respect and it was thought that the spread of diatom species would contribute to Turkey and Iran diatom species. In the rivers, a lot of diatoms which are known as pollution indicator only Achnanthes lanceolata (Brébisson ex.Kützing) Grunow, Caloneis ventricosa (Ehrenberg) F. Meister, Cyclotella meneghiniana Kützing, Diatoma elongatum (Lyngbye) C. Agardh, Gomphonema olivaceum (Hornemann) Brébisson, Nitzschia sigmoidea (Nitzsch) W. Smith, Pinnularia brebissonii (Kützing) Rabenhorst, Rhoicosphenia curvata (Kützing) Grunow, Nitzschia palea (Kütz.)W. Sm., Ulnaria acus (Kütz.) M. Aboal, Ulnaria ulna (Nitzsch) Compȇre and Gomphonema truncatum Ehrenberg in the Turkey and Iran rivers. The aim of this study is to assess the diatom of Irani a river and evaluate as an abundance the relation to Turkey rivers
