Syllabus
Prerequisites: The course unit includes knowledges of Mathematics, Physics, Hydraulics and hydrology, General and territorial Agronomy.
Target skills and knowledge: The following knowledge and skills are expected:
1. Ability to make suitable choices for irrigation management of green areas
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
3. To know the methods of the sustainable in-situ management of rainwater in an urban environment using sustainable urban drainage systems, with particular regard to the construction of green roofs and bioretentions.
Examination methods: The evaluation of knowledges and expected skills is carried out with an oral exam that includes: a. execution of an example of sizing of main, secondary and lateral pipes (preparatory to the continuation of the exam), b. recognition of one or more irrigation devices with a description of the technical characteristics, c. one or two questions on all the contents of the course.
At the end of the course it is possible to perform the preliminary part of Hydraulics related to the sizing of the main and secondary pipes and the drop tubes as written exam.
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 used in green areas
3. Ability to implement optimal choices regarding irrigation system components and irrigation system management
4. Knowledge of the techniques for the stormwater runoff management in urban areas.
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. How much to irrigate: the WUCOLS method. 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.
Sprinkler irrigation: characteristics of the method. Sprinkler irrigation systems in gree areas: portable, semi-portable and fixed systems. Components of irrigation systems. The irrigaiotn sprinklers: types, technical characteristics, optionals. Spray and rotor sprinklers, stationary and pop-up: 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.
Hydraulics: hints 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.
Issues related to sustainable in-situ management of rainwater in urban areas. Blue-green infrastructures for the management of stormwater runoff: green roofs, bioretention ponds, rain gardens, rain barrels, tree box filters, permeable pavements. Green roofs and rain gardens: design elements.
Planned learning activities and teaching methods: The course unit includes hours of classroom lectures accompanied by exercises in the classroom and in the laboratory, exits for technical visits, also with a practical exercise function, and in-depth seminars.
Additional notes about suggested reading: All the teaching material presented during the lessons is made available on the School's Moodle platform.
