OBJECTIVE

The aim of this course is to give civil engineering majors a basic understanding of flow systems in closed and open hydraulic and hydrologic systems. This course is designed to provide detail computation for studying, analyzing and design of components of hydraulic systems such as pipes, pumps, open channels and storm collection systems. Included in this course will be two hydraulic laboratory experiments and three computer lab experiments using a commercial software (i.e. Haestad-Method© software) which help students to design and visualize different hydraulic and hydrological phenomena in professional manner. The following topics will be covered during course work:

  1. Review of the basic hydraulic principles (~1 week): flow characteristics, energy principles, hydraulic grade.
  2. Piping systems (1.5 weeks): pipes in series and parallel, energy gains and losses. Hydraulic Lab 1 (pipe flow experiment).
  3. Pipe Network Analysis (1 week): Computer Lab 1 (Water Distribution Design)
  4. Open channel flow and specific energy losses, critical, supercritical and sub-critical flow (1 week). Hydraulic Lab 2(open channel flow experiment).
  5. Gradually and rapidly varied flow, uniform and non-uniform flow, weir flow and orifice flow (1.5 weeks)
  6. Introduction to hydrology principles (~1.5 weeks): rainfall characteristics, rainfall abstractions and runoff volume, peak runoff computation, computing hydrographs.
  7. Introduction to Haestad Method Software: (~1 week): lecture and lab tutorial.
  8. Surface runoff computations (1 week): Computer Lab 2 (Storm water detention design)
  9. Storm runoff collection design (1.5 weeks): Computer Lab 3 (Storm sewer collection design)
  10. Pumping system design (1 week): pump characteristics, pumps in series, pumps in parallel, pump stations
  11. Reservoirs, wells, storage tanks (1 week)
  12. Examinations and projects’ presentations (~1 week)

Design Project:

Projects will facilitate assimilation of and practicing with concepts learned in class. About 1/3 of this course is designed to produce guidelines and methodologies to design hydraulic and hydrological systems which includes pipes, pumps and storm water collection system using professional design software. For example, students are given a scenario in which certain flow rate has to be provided from a reservoir or well to a higher elevation community via a piping network using storage systems. They have to select from at least four different size pumps and appropriate combination system with a designed pipe system to be sufficient. This process includes decisions on the hydraulic system, efficiency consideration, and cost estimation. Students must use a commercial software (i.e. Haestad-Method© software) to solve, compute, and submit their work.

GRADING CRITERIA

  1. Midterms (30%) – Two midterm exams will be administered during class time. The two exams will contain computing and theoretical components.
  2. Homework (10%) – A total of 10 assignments will be administrated during the semester (one each week)
  3. Project (20%) – Projects will be assigned in the second half of the semester. Students will work in small teams to complete and present the written and the orals parts of projects.
  4. Laboratory Reports (10%)
  5. Computer Lab (10%) – A total of three computer labs will be given. These computer labs will be submitted using commercial software and a written report.
  6. Final exam (20%)
