2. Objectives and learning outcomes
2.1 Objectives
To introduce you to hydraulic structures, water motion, transport processes and their methods of analysis.
2.2 Learning outcomes
Upon successful completion of this subject, the student:
A. Knowledge
  1. Know the equation and the classification of steady-state, gradially varied open flow profiles.
  2. Distinguish between the general formulas for flow over various types of weirs.
  3. Understand the basic hydraulic properties of river flood waves, bores and periodic surface waves; and be able to summarise the laws and equations governing these motions.
  4. Know the principal transport processes and their equations.
  5. Know how to characterise and classify river sediment.
B. Skills
  1. Gain familiarity in solving problems involving hydraulic structures, water waves and groundwater seepage with a calculator.
  2. Be able to perform calculations involving iterations using a spreadsheet software or a programming language.
  3. Can summarise their hydraulic calculations in a written form.
C. Attitudes
  1. Aim at solving numerical problems correctly and accurately.
  2. Support their calculation results by arguments, and document them with sufficient detail so that it reflects a conscious use of hydraulic methods.
D. Autonomy and Responsibility
  1. Implements hydraulic calculation algorithms individually based on the written notes supplied with the problem.
2.3 Methods
Lectures, exercise classes, assignment solved individually, written and oral communications, application of projector and blackboard.

II. Subject requirements

Assessment and evaluation of the learning outcomes
3.1 General rules
The assessment of the learning outcomes specified in clause 2.2. above and the evaluation of student performance occurs via two midterm tests, homework assignment and written examination.
3.2 Assessment methods
Evaluation formAbbrev.Assessed learning outcomes
1st midterm testMT1A.1-A.2; B.1; C.1-C.2
2nd midterm testMT2A.3; B.1; C.1-C.2
homework (small homework)HWB.2-B.3; C.1-C.2; D.1
written examinationEA.1-A.5

The dates of deadlines of assignments/homework can be found in the detailed course schedule on the subject’s website.
3.3 Evaluation system
Total achievable during the semester50%
3.4 Requirements and validity of signature
To get the signature you must exceed 40% of the maximum score of both midterm tests and prepare the homework individually, without sharing with others, at a sufficiently good quality.
If you already obtained the signature in a previous semester and you join a normal (not an exam) course, then your new result will overwrite any previous result.
If you have achieved midterm results counting towards your exam grade of this subject sometime in the four previous semesters, then these results may also be accepted in the current semester.
3.5 Grading system
An exam not exceeding 40% of the maximum score results in a failed (1) exam.
If you pass the exam then the final grade is calculated as the weighted average of the midterm tests, homework and final exam as specified in Clause 3.3.
Grade Points (P)
excellent (5) 85%<P
good (4) 70%<P<=85%
satisfactory (3) 55%<P<=70%
passed (2) 40%<P<=55%
failed (1) P<=40%
3.6 Retake and repeat
  1. Late homework can be submitted till the deadline determined in the Detailed course schedule, after paying the fees due according to the regulations.
  2. Any of the two midterm tests can be retaken at the time and place specified in the Detailed course schedule. This first retake is free regardless of your previous score, i.e., you can also retake in order to improve the score of a passed midterm test. In any case the new score overwrites the previous.
  3. If you cannot pass the subject (obtain a final grade higher than 1) with the retake in clause (2) then you can try to improve one failed midterm test a second time. This second retake is not free, however: you must pay the due fees according to the regulations. The time and place of the second retake is also specified in the Detailed course schedule.
