Weirs are simple control structures usually built across channels for water storage and measurementof flow rates. The main target of the present study is to numerically simulate experimentally thehydraulic performance circular crested normal weirs. For numerical simulation, commercialpackage ANSYS CFX utilized adopting tetrahedrons mesh with a maximum total number 1932301elements, while, experi...

Truncated sharp crested weirs are used to measure flow rate and control upstream water surface in irrigation canals and laboratory flumes. The main advantages of such weirs are ease of construction and capability of measuring a wide range of flows with sufficient accuracy. Artificial neural networks (ANNs) and genetic programming (GP) have recently been used for estimation of hydraulic data. In...

The author is engaged, entertaining, and never judgemental. At times, though, scholarly objectivity must have been a challenge for her — for example, when folk remedies call for acts of immense cruelty towards innocent amphibians (like the tongue removal above), or when fables advocate socially unpalatable attitudes (a frustrated male viper lauded for having sex with lampreys). I would have bee...
