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...

Surface topography of jet shock cells in a hydraulic analogy

The photograph in Fig. 1 (top) shows text visualized through free surface flow, which serves as a hydraulic analogy of an underexpanded two-dimensional jet at Froude number 1.35 [analogous to Mach number (Buchanan et al. 2007)]. The text is illuminated by a halogen lamp from below a water table and used as a Fig. 1 Photograph (top) of the analogy to shock cells downstream of a nozzle at Mach nu...

Downstream hydraulic geometry of alluvial rivers

This article presents a three-level approach to the analysis of downstream hydraulic geometry. First, empirical concepts based on field observations of ‘poised’ conditions in irrigation canals are examined. Second, theoretical developments have been made possible by combining basic relationships for the description of flow and sediment transport in alluvial rivers. Third, a relatively new conce...

Investigation of Hydraulic Problems in Pumping Station; Case Study

Pumping stations play an important role in agriculture development projects. Performance of the pumping stations should satisfy water requirements, and management. There are many problems face these pumping stations affecting their reliability and stability. Hydraulic problems are the most important item in the field of pumping station operation and design. Motivation of this research was prese...

Generalized hydraulic geometry: Derivation based on a multiscaling formalism

[1] Relationships between channel characteristics (e.g., mean depth, water surface width, mean velocity) and discharge, known as hydraulic geometry (HG), have been extensively used by hydrologists and geomorphologists since the seminal work of Leopold and Maddock [1953]. On the basis of recent empirical evidence that the parameters of at-site HG depend systematically on the contributing area (s...
