Course Aim: To provide knowledge on analysis of open-channel flows, boundary layer flows, and coastal processes with their applications in practice.

Intended Learning Outcomes:

On successful completion of the course, the students should be able to;

➢    solve simple viscous fluid flows using Navier-Stokes equations, explain the approach to solve turbulent boundary layer flows and estimate drag forces.

➢    apply mathematical principles for the analysis of steady, non-uniform flows in open channels using energy and momentum considerations and analyze flow profiles for steady, non-uniform open channel flows.

➢    analyze coastal hydraulic processes that need to be considered in coastal engineering designs.

➢    analyze and design unlined channels on erodible beds, and explain sediment transport processes in inland and coastal waters

Course Content:

➢    Viscous flow: Navier-Stokes equation: some solutions; Flow past solid boundaries; Laminar and turbulent boundary layers, flow separation, drag, Reynolds-averaged Navier-Stokes equation.

➢    Frictionless flow in open channel: Specific energy and flow force, hydraulic jump, flow transients, flow measurements.

➢    Resistance in open channel flow: Uniform flow; Chezy’s equation, Manning’s equation, gradually varied flow, flow profiles.

➢    Coastal Hydraulics: Coastal environment, application of wave theory, nearshore wave-current processes.

➢    Sediment transport processes in open channels and in coastal areas: Initiation of sediment motion, stable channel design, transport formulae, erosion and deposition in inland waters, sediment transport processes in estuarine and coastal areas.
