Investigation of hydraulic regime at middle part of the Loire River in context of floods and low flow events

摘要: Significant variability characterizes natural streams in space and time that describe hydraulic regime of the entire stream. In this paper, importance investigation assessment system context management surface water resources is discussed. The objective study to investigate middle part Loire River located France. basin largest river France origin many potential flood events. Investigation a conducted using traditional simulation model HEC-RAS. Hydraulic modeling carried out by considering two different datasets (i.e. low flow events). A certain number structures, which have significant effect on river, considered as well. Through Froude computation, it noticed demonstrates subcritical regime. Accurate calibration validation are performed changing Manning coefficient along riverbed. Computation for both data sets; show there no big differences between observed simulated levels, results obtained satisfactory. Therefore, get more accurate information about at River, further needs be done an additional dataset floods
