Abstract Samples of benthic invertebrates were collected from riffle sites on two river systems in the southern Alburz Mountains in the neighbourhood of Tehran. Iran. Main river channels had a fauna of Oligochaeta, Plecoptera, Ephemeroptera, Trichoptera, Coleoptera, Diptera and Potamonidae and downstream changes in community structure were observed. Tributary streams had few or no benthic invertebrates. The main factors determining fauna appeared to be frequent flooding and high levels of suspended solids caused by quick run-off of rain and melting snow from the bare, eroded and degraded mountain sides.
