Objectives

The course has as main objective to convey to the students a whole set of complementary knowledge on Hydraulics and Hydrology. The concepts and methods presented are expected to be applied in the design of river channels and structures, including the protection of beds and banks and using physical and numerical models and computational simulation for the study of natural river systems. Such knowledge will also complement the notions related to the design and hydraulic dimensioning of river works, namely those associated with the realization of hydraulic projects, and to identify, prevent and mitigate associated environmental impacts.

 

With the frequency of the curricular unit, students will be prepared to be integrated into the execution of a project, supervision, coordination and control of the execution of current fluvial works.

Learning outcomes and competences

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Non-attendance and/or non-approval in the course units Hydraulics 1, Hydraulics 2, and Urban Hydrology and Hydraulics may lead to increased difficulties.

Teaching methods and learning activities

Teaching involves lecture sessions (T) and discussion sessions (TP).

Theoretical classes: All topics of the programme are presented in lectures focusing mainly on basic theoretical aspects: however, some more theoretical-practical aspects can be also addressed when related to specific subjects.


Practical classes: The theoretical classes are complemented with practical problem-solving applications on several subjects, which is effective in the practical classes. This experience of the resolution of concrete cases of application allows students to better integrate the different subjects analysed.


DEMONSTRATION OF THE COHERENCE BETWEEN THE TEACHING METHODOLOGIES AND THE LEARNING OUTCOMES:
The used teaching methodologies allow the approach of the essential subjects associated with river works, the analysis, discussion and critical interpretation of solutions, highlighting the potential of written communication, problem formulation, application of knowledge and regulatory verification. The realization of practical works and discussion of the subjects allows efficient learning at this level of education.

Eligibility for exams

Achieving final classification requires compliance with attendance at the course unit, according to the M.EC assessment rules. It is considered that students meet the attendance requirements if, having been regularly enrolled, the number of absences of 25% for each of the classes’ types is not exceeded.

Calculation formula of final grade

The final grade is defined with basis on a “Final Exam” (EF) and two "Practical Works" (TP1 and TP2), being these two last optional, to be held outside of class sessions.
                                    
EF: Exam to be performed in the normal or re-sit examination season, with a theoretical part (without consultation) and a practical part (without consultation), with the maximum total duration of 3.0 hours (evaluation expressed on a 0-to-20 numerical scale, rounded to one decimal place: theory – 50%; practice – 50%).

Distributed Evaluation Components (optional):

TP1: practical work 1, to be developed outside class sessions, within the scope of Natural River Systems Simulation - Hydrological and Hydraulic Modeling (1D and 2D).  (classification from 0 to 20, rounded to one decimal place).

TP2: practical work 2, to be developed outside class sessions, in the scope of Protection and Stabilization of Beds and Banks. (classification from 0 to 20, rounded to one decimal place).

The FINAL GRADE (CF) will be the best grade obtained by the following formulas:


CF1 = 0.750 EF + 0.125 CAD1 + 0.125 CAD2

CF2 = 0.875 EF + 0.125 CAD1

CF3 = 0.875 EF + 0.125 CAD2

CF4 = 1.000 EF

i.e., CF = maximum {CF1, CF2, CF3, CF4} (CF rounded to the unity).

Special assessment (TE, DA, ...)

The students with a Special Status are classified according to the method presented in "Final grade", EXCEPT when they undergo examination in a Special Season. In this case, according to the NGA, students are evaluated in a “single evaluation moment”, which consists of an exam with the same characteristics of the Final Exam (FE). The Special Exam grade is expressed on a 0-to-20 numerical scale, rounded to the unity: theory – 50%; practice – 50%.

Classification improvement

The students that have already obtained approval in the course unit can perform CLASSIFICATION IMPROVEMENT, only once, and exclusively by a Final Exam (EF), to be performed in the two following examination seasons (Normal or Re-sit).


Being the classification improvement performed exclusively by a Final Exam (evaluation expressed on a 0-to-20 numerical scale, rounded to the unit), there is no room for improvement of the classification of the Distributed Evaluation Components.


The Final Grade in the course unit is the highest between the one initially obtained and the one resulting from the classification improvement.
