Course abstract

Design of the sprinkler irrigation system (equipment and practice). Design of the solid-set pressure pipe line network, field layout and longitudinal section of pipe lines. Irrigation water source, pump station and hydraulics of pipelines. Consumptive water use of crops and irrigation requirement.

Learning outcomes and their assessment

• The course develops knowledge and professional understanding about the design of irrigation systems.
• The course enables students with an ability to develop the layout of sprinkler system using topographical maps and longitudinal cross sections of the pipelines and to perform technical calculations.
• The course elaborates competence to use technical norms, practical skills to elaborate design projects in other fields of Water Management.

Course Content(Calendar)

1. Designing the irrigation system, choosing irrigation equipment (2h)
2. Designing hydrants of a stationary system in the plan (2h)
3. Designing profiles of the system (2h)
4. Selection of pumps, calculations of hydraulics (2h)
5. Irrigation system fittings (2h)
6. Irrigation system equipment (2h)
7. Watering regime (2h)
8. Formal design of project profiles and plan materials (1h)
9. Oral defense of course project solutions (1h)

Part time extramural studies:
All topics specified for full time studies are accomplished, but the number of contact hours is one half of the number specified in the calendar

Requirements for awarding credit points

A course project must be developed and defended (irrigation system project, with explanatory text, project plan M 1:2000, profiles of pressure pipes, hydraulic calculation tables, specifications of pressure pipes and constructions)

Description of the organization and tasks of students’ independent work

During the course, students independently develop an irrigation system project in consultation with the instructor. The teacher offers the output data, including the topographical plan, soil composition, geographical location, etc. The project is developed in accordance with the construction project quality requirements adopted in Latvia, with an appropriate level of detail, including design in the plan and profiles. The explanatory part shall include a description of the project's technical information, calculations, material specifications and calculation of the irrigation regime.

Criteria for Evaluating Learning Outcomes

The final grade consists of an assessment of the developed course project (80%) and the answers provided by the student during the defense (20%)
