Objectives

The course of “hydraulic plants and fluvial works 2” has as a fundamental objective to provide the students of the 5th year of the MSc in Civil Engineering, who chose the Hydraulics Option as specialization area, with knowledge on hydraulic plants and fluvial works that was not possible to present in the disciplines of General Hydraulics and Hydrology and Water Resources, which belong to thecommon core of the degree.
This knowledge is mostly related with the design of the plant, the hydraulic design of elements of the installation, the environmental impacts associated with the establishement of the plant and the schedule of the corresponding project. With this course unit, the students will be prepared to integrate and carry out project tasks, supervision, coordination and monitoring of the implementation as well as the construction of the most common hydroelectric plants.

DEMONSTRATION OF THE SYLLABUS COHERENCE WITH THE CURRICULAR UNIT'S OBJECTIVES: 
This course unit covers the topics on hydroelectric plants, interventions in rivers, which are essential to the preparation of civil engineering professionals highly qualified to deal with these issues at the level of conception, design, implementation and monitoring of interventions.

Teaching methods and learning activities

All the topics of programme are presented in lectures focusing mainly basic theoretical aspects: however, some more theoretical-practical aspects can be also addressed when related with specific subjects. The theoretical classes are complemented with practical problem solving application 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. A component of the teaching method of the discipline that is considered important concerns the professional experience that is conveyed to the students by the technical visits. Apart from visits to hydroelectric plants already implemented, the opportunity to visit projects under construction is also given to the students.

DEMONSTRATION OF THE COHERENCE BETWEEN THE TEACHING METHODOLOGIES AND THE LEARNING OUTCOMES:
The used teaching methodologies allow to deal with main themes related to fluvial works and hydroplants, analysis, discussion and critical interpretation of results, emphasizing the potential of writing communication, problem formulation and certification.

Eligibility for exams

Achieving final classification requires compliance with attendance at the course unit, according to the MIEC 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 of Hydraulic Power Plants and River Works 2 is defined with basis on a “Final Exam” (EF) and two Distributed Evaluation Components (CAD1 and CAD 2), being these two last optional and on dates to be sheduled each year:

                                       
EF: Exam to be performed in the normal or re-sit examination season, with a theoretical part (without consultation) and a practical part (with 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):

CAD1: Distributed Evaluation Component 1, to be performed on a schedule coincident with theoretical or practical classes, with a maximum duration of 1h (evaluation expressed on a 0-to-20 numerical scale, rounded to one decimal place);

CAD2: Distributed Evaluation Component 2, to be performed on a schedule coincident with theoretical or practical classes, with a maximum duration of 1h (evaluation expressed on a 0-to-20 numerical scale, rounded to one decimal place);

According to the MIEC Evaluation Rules (paragraph 3.2.d), students have the possibility of substituting one or the two Distributed Evaluation Components by the Final Exam. Therefore, 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).

Note 1: The evaluation components, associated to CAD1 and CAD2 are optional. If the student does not take one of them, the associated weight will be added to the Final Exam.

Note 2: The Final Exam (EF) covers all the course unit subjects.

Note 3: The Distributed Evaluation Components (CAD1 and CAD2) focus on subjects related with the developed work in theoretical and practical. The topics on which each Distributed Evaluation Component will be indicated timely.

Note 4: ALL students enrolled in the course unit are classified according to this method, i.e., students with a special status are also evaluated according to this method.

Note 5: For the calculation of the Final Classification (CF) ONLY the components (EF, CAD1 and CAD2) of the CURRENT school year are considered (i.e., marks for the Distributed Evaluation Components from former years ARE NOT considered). 

Note 6: The students enrolled to the Final Exam for classification improvement (see specific rule) are excluded from this method of calculating the final grade, as well as the students with a special status undergoing examination in a special season (see specific rule).

Note 7: Improvement of the Distributed Evaluation classification is not allowed (see specific rule).

Note 8: The students that miss a Distributed Evaluation Component (CAD1 or CAD2), with a justification accepted by the Director of MIEC, have the possibility to perform a re-sit test (but only once) to be scheduled with the Responsible Professor of the course unit.

 

Examinations or Special Assignments

Students have to do some practical assignments in practical classes.

Special assessment (TE, DA, ...)

Students with Special Statute are classified according to the method explained in "Final Classification Calculation", EXCEPT when they undergo examination in the re-sit season. In this case, according to the NGA, the students are evaluated in a single moment, which will consist of a sigle test with similar characteristics as the Final Exam (EF). The classification of the Special Exam will be based on a 0-20 numerical scale, rounded to the unit (Theory - 10 points, Practice - 10 points).

SPECIAL RULES FOR MOBILITY STUDENTS:

Previous attendance of introductory graduate courses in the scientific field addressed in this course unit; Proficiency in Portuguese and/or English;

Mobility students may perform the Final Exam and the Distributed Evluation Components in Portuguese or English, if requested. Mobility studentswill be given tutoring in English during the practical classes, if they so request.

Classification improvement

Students who have already obtained approval may perform an IMPROVEMENT OF CLASSIFICATION, only once, exclusively for the Final Exam (EF) to perform in the two seasons (Normal or Re-sit) immediately following the one in which they passed.

With an improved classification performed exclusively by final exam (EF) (expressed on a 0-to-20 numerical scale​​, rounded to the unit) there is no place to improve the classification of Distributed Evaluation Components.

The final grade of the course unit is the highest, between the one originally obtained and the one resulting from the improvement of classification performed.
