This course of 15 lectures provides an introduction to open channel hydraulics, the generic name for the study of flows in rivers, canals, and sewers, where the distinguishing characteristic is that the surface is unconfined. This means that the location of the surface is also part of the problem, and allows for the existence of waves – generally making things more interesting! At the conclusio...

Stuff happens. That’s one of life’s rules. Some of it is of profound importance or even historical in nature. Some is routine or of no major significance. The rest depends on who you are, what you are doing, or where you are or where you are going. But, regardless, learning about what’s happening in the world gives us awareness and allows us to assess implications, make decisions, and respond w...

water distribution method based on the type of water conduits can be divided into two groups, namely, open and closed systems, while on the basis of the energy of the water flow, the two groups are gravity flow and pressurized flow. open channel type conveyance and distribution is achieved by gravity and includes channels made by embankment construction, excavation, or construction of prefabric...

In the Manning equation the hydraulic radius can be defined as the cross-section dimension of the shape. In pipe flow the bed shear stress is assumed to be uniformly distributed along the wetted perimeter which cannot be true in open channel flow. Hence, three approximation of the true boundary shear-stress distribution are examined and more practical conveyance depth or resistance radius formu...

This paper presents the results of a numerical study on the heat transfer performance and the removal process of fluid particles under the influence of magnetohydrodynamic mixed convection in a horizontal channel with an open cavity. The bottom wall of the cavity is heated at a constant temperature (Th) while the top wall of the channel is maintained at a relatively low temperature (Tc). Air wi...

During the past decade, the trend to couple the World Wide Web (WWW) in teaching and learning has been gaining momentum rapidly. Learning availability over the Internet is expanding and gradually constitutes a usual means of education and training. In this paper, the development and implementation of an AI-based interactive teaching package for open channel flow on Internet is depicted. The lat...

Total Channel ControlTM is a patented automation design for large scale open canal irrigation networks that manages water distribution within capacity constraints to achieve on-demand water delivery whilst maximizing water distribution. Here it is shown that this decentralized and distributed control implementation realizes near globally optimal performance. Furthermore, the performance enhance...

Additive Manufacturing (AM) offers a range of possibilities in fluid flow research. An existing 2.5 m open channel experiment contains set standard weirs which are limited design. This research will compare experimental AM (e.g. labyrinth, piano, catenary), that would not be possible on some laser-cut polymer or machined aluminium weirs. Due to the bespoke complex nature weirs’ design other man...
