Syllabus

Module I (10hrs)
Hydraulics of alluvial rivers: regimes and morphology. Critical tractive force and resistance relations. Suspended, Bed and Total loads. Meandering, Braiding, Aggradation and Degradation.
Module II (10hrs)
Routing of floods – reservoir and channel routing. Direct and indirect methods of measurements of flow. Direct methods: Weirs, flumes. Indirect methods: Velocity area method, Slope area method. Module III (10hrs)
Rating curves, float method, use of current meter for velocity area method using mean section method and mid-section method. Stage discharge rating curve. Interpolations for zero discharge stage. Corrections for rising and falling of stage due to unsteady conditions. Ultrasonic methods and other recent methods and tracer techniques
Module IV (10hrs)
Unsteady flow, dynamics of gradually varied unsteady flow, solution of unsteady flow equations, rapidly varied unsteady flow, positive and negative surges, Compound channels, flow computation of a two stage channels by different methods.

1. To prepare the students for a successful career as hydrologist and water resources engineers

2. Ability to analyse river flow hydraulics

3. Ability to analyse hydraulic geometry and to design stable alluvial channels

4. Ability to plot the rating curve at any section

At the end of the course, students must be in a position to
1. Find the total load of the hydraulic structure
2. carry out the flood routing
3. find out the velocity of the river flow
4. to plot stage discharge rating curve
5. understand the flow regimes in open channels
