Learning Outcomes
The aim of the course is to introduce the calculation of steady and non-steady flow in ducts with a free surface (open ducts) by applying the basic equations of fluid mechanics.The student acquires knowledge of the methodology and the ability to create simple computational models for problems of flow under pressure and flow with a free surface as well as the theoretical background for dealing with computational problems and simulation and design problems in the application courses that follow such as engineering hydrology, land reclamation works (irrigation-drainage), urban drainage, river hydraulics and river training, etc. Sufficient knowledge of the course provides an important theoretical resource for the study and design of hydraulic works and related constructions.
Knowledge
The course helps students develop their technical and intellectual skills, preparing them for the engineering profession and for postgraduate studies. The course introduces the students to Open Pipe Hydraulics computational techniques used in the professional practice of the Rural and Surveying Engineer.
Ability
After completing the course, the student possesses advanced skills in processing, analyzing and solving complex problems of the hydraulics of open pipelines in a steady flow state related to the Design of hydrotechnical projects.
Skills
After completing the course, the student manages complex work plans and is able to make decisions on the design of hydrotechnical projects. Also, he is able to work individually and in a group during the design of hydrotechnical projects. Especially students will be able to
• to design/evaluate studies of hydrotechnical projects and
• to synthesize and propose optimal or new solutions based on the above consideration.
