Engineering geomorphological assessment of lower Gamasiab river in east of Kermanshah province

Awareness of Morphological features of rivers is nessesary for recognition of river behavior and optimum aplication of rivers. Overall catchment Physiografy have important role for determination factors such as floods، erodible and sediment mutagenicity. In this study in order to understand behavior of Gamasiab river in the east of Kermanshah provice، geomorphologic features of this river has been considered. Study of engineering geomorphologic properties is done by using existing data from previous studies and according to visit site and field perceptions، study of geology and topography maps. Physiographic properties of catchment، chanels morphologic properties and geology conditions in this region has been studied. In this research، several parameters such as average width، environment، area، hydrogeologic coefficient، catchment form، maximom، minomom and mean higth، and longitudinal slope has calculated. Also status of drainage density of this river investigated and time to focus calculated. Finally this river review and classified according t various classifications for rivers.
