Pokhara University
1. Course Description
This course provides necessary insight of the fundamental principles, design, and operation of storage and ROR hydropower systems. It covers the theoretical and practical aspects of harnessing water energy for power generation, with emphasize on design of hydraulic structures. Key topics include site selection, energy calculations, design of headworks, penstocks, powerhouses, and environmental considerations in hydropower development.
2. General Objectives
The course is designed with the following general objectives:
- To familiarize the students with the phases of hydropower development and planning procedures for both storage and ROR projects
- To enable the students to analyze power and energy calculations in storage and ROR projects
- To enable the students to design headworks components, hydromechanical components, various Hydraulic components, and plan powerhouse for Hydropower projects

7. Evaluation System and Students' Responsibilities
Evaluation System
In addition to the formal exam(s) conducted by the Office of the Controller of Examination of Pokhara University, the internal evaluation of a student may consist of class attendance, class participation, quizzes, assignments, presentations, written exams, etc.
Internal Evaluation
Component | Weightage |
---|---|
Theory | |
Attendance & Class Participation | 10% |
Assignments | 20% |
Presentations/Quizzes | 10% |
Internal Assessment | 60% |
Practical | |
Attendance & Class Participation | 10% |
Lab Report/Project Report | 20% |
Practical Exam/Project Work | 40% |
Viva | 30% |
Total Internal Marks: 50
Semester-End Examination: 50
Full Marks: 50 + 50 = 100
Students' Responsibilities
Each student must secure at least 45% marks in the internal evaluation with 80% attendance in the class to appear in the Semester End Examination. Failing to obtain such score will be given NOT QUALIFIED (NQ) and the student will not be eligible to appear in the End-Term examinations. Students are advised to attend all the classes and complete all the assignments within the specified time period. If a student does not attend the class(es), it is his/her sole responsibility to cover the topic(s) taught during the period. If a student fails to attend a formal exam, quiz, test, etc. there won't be any provision for a re-exam.
