Bio-engineering for landscape restoration

Academic Year 2025/2026 - Teacher: FELICIANA LICCIARDELLO

Expected Learning Outcomes

1) knowledge and understanding

The course provides knowledge about the possible applications of soil bioengineering techniques in interventions such as: soil protection, hydraulic management of watercourses, restoration of degraded and/or contaminated sites (landfills, quarries, etc.), mitigation of impacts caused by the construction of specific infrastructures (roads, railways, etc.), environmental rehabilitation of wetlands, and watercourse remediation through phytoremediation and lagooning systems. Furthermore, the student will develop practical skills in the design of soil bioengineering works, using plants and traditional construction materials (wood, stone, steel, etc.), with particular focus on techniques that can be applied in arid and semi-arid climates. Special attention will be devoted to Nature-based Solutions (NBS) for hydraulic risk mitigation in urban and peri-urban areas.

  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


6) Contribution to the goals of the 2030 Agenda for the Sustainable Development

Goal No. 6: CLEAN WATER AND SANITARY SERVICES

GOAL 11: SUSTAINABLE CITIES AND COMMUNITIES

GOAL 13: COMBAT CLIMATE CHANGE

GOAL 14: LIFE UNDER WATER

GOAL 15: LIFE ON EARTH

Course Structure

Credit total amount: 6

Total hours 63 (21 hrs for lectures and 42 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

Attendance is not compulsory, however it is strongly recommended in particular on days dedicated to exercises.

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. Use of Nature-Based Solutions for the reduction of hydraulic and hydrogeological risk in hydromorphological and urban contexts.
