Abstract :

The Sarghaye – Sarnish watershed with elongate shape and around 70.654 Km2 surface area is located at south of Mashhad. The grain size variation has been analyzed at 20 sites to led identification of effective factors in downstream fining at the second main branch of the watershed. One discontinuity and two sedimentary links have been recognized based on acquised data. The discontinuity is resulted from increase slope and exposure bed rock. The isolated sedimentary links have fining trend to downstream due to hydraulic sorting and abrasion. The result of assessment of modern deposits in surrounding Sarnish river demonstrate three facies associations that consist of debris flow deposits, stream flow deposits and overbank deposits. First facies associations includes two main Gravelly facies (Gcm) and (Gmm); Other two facies associations consists of (Fm) and (Sm), respectively.
