Prerequisites: No special requirements and no prerequisites.
Target skills and knowledge: The following knowledge and skills are expected:
1. Ability to make suitable selection of the methods and techniques for the rational management of crop irrigation
2. Being able to recognize the different components of the irrigation systems and know their technical features in order to correctly design, install and maintain the irrigation systems
Assessment criteria: The evaluation is based on:
1. Ability to correctly sizing a main line of irrigation system
2. Level of technical knowledge acquired concerning the various devices of sprinkler and micro-irrigation systems
3. Ability to implement optimal selections regarding irrigation system components and irrigation system management
The presence at the classroom exercises and at the technical visits is positively evaluated.
Course unit contents: The water resource. Rational use of the water resources: the current legislation. Definitions of irrigation. Rational management of irrigation in green areas: rules to limit the water wastes.
Selection criteria of the irrigation method. Water uses: the physical partitioning of water, consumptive uses and nonconsumptive uses, the judgmental partitioning of applied irrigation water. The parameters for the evaluation of irrigation systems design and management: efficiency and distribution uniformity. Distribution uniformity: methods for the field detection.
Irrigation methods: classification and description. Surface irrigation: types, techniques for improving the water distribution and automation.
Sprinkler irrigation: characteristics of the method. Sprinkler irrigation systems: portable, semi-portable and fixed systems. Components of irrigation systems. Sprinklers: types, technical characteristics, selection criteria, precitation profiles and distribution patterns. Sprinklers installation and causes of poor uniformity.
Microirrigation. Emitters: types, characteristics, selection criteria. Emitter discharge exponent and coefficient of manufacturing variation. Emitter system types. Subsurface drip irrigation. Emitter location and installation. Greenhouse irrigation systems.
Pipe and fittings: materials, characteristics of PE and PVC pipes. The mechanised irrigation systems: side roll, Travelling gun systems, Center Pivot, Linear Move; LEPA,LESA and MESA systems.
Hydraulics: basics of hydrostatics, static and dynamic pressure, Newton's law of viscosity, laminar flow and turbolent flow, Bernoulli's priciple, Venturi effect, friction losses, application of the Darcy-Weisbach equation for the sizing of the main pipelines. Fittings and components losses. Hydraulics of lateral and submain pipelines.
Water supply for irrigation. Water treatment: causes of emitter clogging. Storage reservoirs. Filtration: sand separators, sand media filters, screen filters. System maintenance: chlorination and acid addition. Fertigation. Injection methods.
Pumps: types and characteristics. Cavitation. Centrifugal pumps, turbine pumps, submersible pumps. Selection criteria. Water hammer.
Valves and devises. Irrigation systems automatation: sensors and monitoring systems, controllers, centralized control systems. Design elements of irrigation systems.
Planned learning activities and teaching methods: The course includes classroom lectures, field trips, practical training, and seminars.
