Direct measurement of discharge in rivers is time-consuming and costly, and sometimes, impossible under flood conditions because of the high speed of water, its transitory nature, and the existence of different floaters along the water. Therefore, the discharge-stage relation, known as Discharge Rating Curve is used. Moreover, to design hydraulic constructions, the maximum flood discharge and i...

رستمی خلج, محمد,

Complex in hydrological and hydraulic processes are one of the distinguishing features of urban areas. Therefore, accurate determination of the input variables of urban models and their impact on model output is time consuming and difficult. Sensitivity analysis shows which parameters impact more severely the results and ranked model parameters according to their effect on model output which ca...

Transfer of debris flow caused by floods in the river downstream of the mountains leads to several damages every year. Numerous researches have been carried out on the Mountain Rivers the results of which show the importance of performing more researches to control debris flows in the floodplain because of various effective hydraulic-geometric parameters.For this purpose, AbNik Mountain River l...
