Qara-Chai River sediment survey of the Markazi province numerical model HEC-RAS.4
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 10
Abstract
Estimate the amount of sediment load and transfer it to a lot of land and water resources projects such as the removal of a river bend, narrowing rivers, flood control, navigation, water went, and the design of dams and reservoirs to store surface water is necessary. The purpose of this study was to estimate and calculate sediment transport capacity of the Qara-Chai river in the Markazi province. After the interval length of 31 km of the river and provide basic information such as cross sections, Information about the geometry of the river, at different levels of roughness coefficients, information about the sediment, suspended sediment and river bed granulation, information about the hydrology of the river system hydraulic boundary conditions and sediment discharge and flow model using HEC-RAS was estimated. The results showed that the equations Englund Hansen, Peter Meyer - Muller, and Toffaleti the measured data is closer than other relations One of these methods is recommended in the river. Also part of the diagram Halstrum and Shields River at the deposition and erosion of the part.
