Description
This course is best suitable for civil engineering students and all personal involved in water engineering. This course is structured into five sections with 17 lectures, each covering a specific topic related to open channel flow.
The sections are as follows:
Section 1: Introduction to Open Channel Flow
In this section, there are definitions, examples and characteristics of open channel flow. You will know the geometry of the open channel, the difference between flow types. You will learn also how to use the Reynold’s and Froude numbers to classify different types of open channel flow regimes.
Section 2: Flow Rate and Velocity Distribution
In this section, you will know the velocity distribution, and the difference between flow through pipe and flow through open channel. You will also know how to calculate the forces cause flow motion in open channel.
Section 3: Design of Open Channels.
In this section, you will learn how to design open channels for various purposes. You will learn how to select the appropriate cross-section. You will learn how to use the Manning equation and the Chezy equation to calculate the normal depth and the discharge in uniform flow. You will learn how to design open channels for uniform flow using various criteria. You will also learn shear distribution in open channel and how to design the stable cross section according to shear stress.
Section 4: Energy Principle in Open Channel
In this section you will know the specific energy and main equation for it. You will know the alternate depths and how to calculate the critical water depth for different cross sections. You will also know what the hydraulic jump is, its properties and when it occurs.
Section 5: Gradually Varied Flow in Open Channels
In this section, you will learn how to analyze gradually varied flow in open channels, which is a type of nonuniform steady flow. You will know how to classify the channel bed slope, the different groups of water curves which occur and how to select the suitable curve. You will also learn how to sketch the water surface profile for weir, gate and free out fall.
