AEW-23803 Water II


Note: This course can not be combined in an individual programme with HWM-24306 Environmental Hydraulics.
This course is designed for students who need a basic knowledge about hydraulics as an introduction to application oriented courses such as the design of irrigation systems and hydraulic structures. By concentrating on a detailed explanation of the laws of conservation of mass, momentum and energy, the course aims at providing the student a clear understanding of steady water flow through conduits, rivers, canals and soils. The course uses a reader which is compatible with this set-up. In this text book, proofs, derivations, theory and worked examples are given in full, but using simple mathematical notation and an ample amount of clarifying text. The following topics are covered: hydrostatics, measurement of pressure, flow and discharge, flow through pipelines, uniform and non-uniform open channel flow and steady flow around hydraulic structures. The course provides basic knowledge of hydraulics and hydrometry for application in the fields of irrigation, river design, drainage, erosion, water conservation and flood protection.

Learning outcomes:

After successful completion of this course students are expected to be able to:
- apply the laws of conservation of mass, energy and momentum to hydraulic problems;
- calculate hydrostatic and -dynamic pressures and resultant forces on structures;
- calculate water level and flow velocity in uniform open channel flow, when cross sectional area, slope of the channel and roughness are known or can be measured;
- calculate surface level profiles for gradually varying non-uniform flow (back water curve, draw down curve), with the aim to know the consequences of measures in currents and streams;
- measure the discharge in small open channels by using discharge measurement techniques including the velocity area method, the slope area method, the dilution method;
- apply discharge formulas for discharge measurement structures;
- calculate energy losses in closed pipe systems by applying friction coefficients and loss coefficients from literature.


- lectures;
- extensive practicals to practice hydraulic phenomena in the hydraulics laboratory.
Examples are: flow over a weir, hydraulic jump, discharge measurement in open channels, visualizing energy loss, backwater and draw down curves.


The mark for the course will be based on written examination of theory, and a written exam based on the practical assignments. The course consists of 6 credits; 4.75 credits are reserved for the theoretical part, and 1.25 credits for the practical part. The final mark is for 80% based on the theory exam, and for 20% based on the practical exam. 


A reader and a practical guide are made available at the WUR-shop; exercises, including answers can be downloaded from Brightspace.
