Abstract

The problem of resistance to flow in the Nile River has changed after the closure of the Aswan High Dams across the Nile River in 1964. During recent years the necessity of determining the effect of vegetation on the hydraulic roughness of the stream of Nile River has become apparent. Many previous studies suggest the division of total resistance into vegetation resistance and form resistance without direct evidence. The study is mainly concerned with the Damietta branch of the Nile River. The results of the determination of the roughness coefficient n for five sections by field measurements are presented in this study.
