Analysis of Flood Hydraulic in Alluvial Fan River using CCHE2D Case Study: (Roodan River)

In this study the advantages and importance of a numerical model to predict and monitor the processes governing hydraulic changes alluvial fan river is discussed. For this reason and because of the importance of flow velocity and shear stresses resulting from the erosion of the river, A two-dimensional numerical model to simulate the CCHE2D river changes ranging from Roodan River is used. In th...

Estimation of river discharge, propagation speed, and hydraulic geometry from space: Lena River, Siberia

[1] Moderate Resolution Imaging Spectroradiometer (MODIS)–derived measurements of Lena River effective width (We) display a high predictive capacity (r 2 = 0.81, mean absolute error < 25%) to forecast downstream discharge conditions at Kusur station, some 8 d and 700 km later. Satellite-derived mean flow propagation speed (88 km d 1 or 1.01 m s ) compares well with that estimated from ground da...

investigation of tectonic activity effects on the river channel geometry and hydraulic (a case study: khartutriver)

1. introduction the analysis of drainage networks is a powerful tool to detect recent tectonic activity and uplift, as river channels are very sensitive to changes in the parameters that control their shapes and. climate changes, tectonics and lithology affect river equilibrium conditions and hence, river geometry. a river is in dynamic equilibrium when erosion keeps pace with sedimentation and...

The Hydraulic Geometry

Some hydraulic characteristics of stream channels — depth, width, velocity, and suspended load — are measured quantitatively and vary with discharge as simple power functions at a given river cross section. Similar variations in relation to discharge exist among the cross sections along the length of a river under the condition that discharge at all points is equal in frequency of occurrence. T...
