Soil bioengineering for watershed protection
Academic Year 2022/2023 - Teacher: Giuseppe CIRELLIExpected Learning Outcomes
1) knowledge and understanding
Supply scientific and technical knowledge on soil bioengineering.. The course provides criteria for river and slope restoration by soil bio engineering techniques, with particularly reference to small mountain catchments. Specific topics on the use of native plants and principles of river restoration in Mediterranean environments. Reclamation of water courses and use of nature based solution for water management and treatment.
2) ability to apply knowledge and understanding
the student will be able to assess the need for intervention with naturalistic engineering techniques and will be able to design small works for the reduction and mitigation of hydrogeological risk and the environmental requalification of degraded areas.
3) autonomy of judgment
The student will acquire a specific ability to identify and design the best type of works for the reduction and mitigation of hydrogeological risk and the environmental requalification of degraded areas in relation to the Mediterranean context.
4) communication skills
The student will acquire the technical language for the design and management of bio-engineering works, this skill will be acquired in particular during the exercises and during the meetings with technicians of the sector that will be organized during the course.
5) learning ability
The student will acquire an autonomous in-depth ability by consulting other textbooks and technical manuals available online, this ability will be particularly stimulated by the seminar activities that will be organized during the course
Course Structure
Credit total amount: 6
Total hours 56 (28 hrs for lectures and 28 hrs for applied activities).
The course is articulated in lectures and lab training sessions. Video projector during lectures and labtop for training session with specific softwares will be used.
Technical seminars with invited speakers (technicias) will be performed.
As a guarantee of equal opportunities and in compliance with current laws, interested students can ask for a personal interview in order to plan any compensatory and/or dispensatory measures, based on their specific needs and on teaching objectives of the discipline. It is also possible to ask the departmental contacts of CInAP (Center for Active and Participatory Inclusion - Services for Disabilities and/or DSAs).
Required Prerequisites
A good knowledge of physics and hydraulics is required. Furthermore, a good knowledge of software tools (Excel, GIS ancd CAD) is required.
Attendance of Lessons
Detailed Course Content
The course is articulated in lectures and applied sessions. Main topics: small mountain watersheds; modelling floods in small watershed and measures to mitigate flood effects on river and streams and to restore small watersheds; environmental impact assessment methodologies and techniques to mitigate environmental impacts of some hydraulic facilities (dams, weir, embankment, etc.); water erosion on slopes and soil bio-engineering control techniques, use of native plants in soil bioengineering. Renaturation, Rehabilitation and Ecological Reconstruction of streams, rivers and shorelines. Techniques for watercourse reclamation: vegetated buffer zones, reconstructed and contructed wetland,
