Hydraulic Modeling of a Mixed Water Level Control Hydromechanical Gate [PDF]
, 2011 This article describes the hydraulic behavior of a mixed water level control hydromechanical gate present in several irrigation canals. The automatic gate is termed "mixed" because it can hold either the upstream water level or the downstream water level

Advanced Engineering Materials, EarlyView.This plot compares experimental tensile stress–strain curves (with 4 different strain rates) and corresponding modelled curves (obtained using the optimised sets of Voce and Miller–Norton parameter values shown). The inferred M‐N values, characterizing the creep, are very similar to those obtained via conventional creep testing.

Hydraulic calculation of changeable irrigation sediment reservoir
European Science Review, 2017 In this article we offer a calculation method for the changes in the river sediment distribution with hydraulic parameters. We also determine for measured and accounting distribution of the sediment by length of the river flow.

One-log call iterative solution of the Colebrook equation for flow friction based on Pade polynomials [PDF]
, 2018 The 80 year-old empirical Colebrook function zeta, widely used as an informal standard for hydraulic resistance, relates implicitly the unknown flow friction factor lambda, with the known Reynolds number Re and the known relative roughness of a pipe ...
