| Educational objectives | The aim of the course is to provide the knowledge and the skills needed to apply watershed management techniques also by soil bioengineering measures. Knowledges: 1- Runoff measure and modelization 2- Watershed morphometry 3- Concentration time and peak discharge. 4- Stream classification and characteristics. 5- Effect of riparian vegetation on stream hydraulics. 6. Stream equilibrium slope. 7- Sediment transport and soil water erosion8. Soil-biongineering methods and techniques. 8- Watershed reclamation by soil-bioengineerign measures. 10- Stream reclamation by soil-bioengineering measures. Skills: 1- Calculation of the watershed concentration time 2- Determination of the watershed peak discharge. 3.- Design and check of open channels. 4- Estimation of the effect of bioengineering interventions on the expected soil loss at plot scale. 5- Determination of the stream equilibrium slope. 6- Design and check of river weirs and banks. 8- Design of live cribwalls. Behaviours: 1- active contribution to the course lectures. 2- capability to find suitable technical solutions. |
| Prerequisites | In order to better understand the topics covered in the teaching, the student must have knowledge of physic, agronomy, botany, agro-meteorology, chemistry and microbiology. |
| Teaching methods | The course is structured as follows: Theoretical lessons dealing with all the issues of the course. The course includes some lessons related to practical training. These are both individual and group exercises that will be sometimes held in the computer room where the students can solve complex or long mathematical calculations by using calculation sheets. Handouts and slides of the lectures are available and the students have access to online learning platforms. |
| Other information | Scheduling of lectures and examinations available at: http://dsa3.unipg.it/ |
| Learning verification modality | The final examination includes an oral exam consisting of a discussion lasting about 40 minutes aimed at ascertaining the level of knowledge and understanding achieved by the student on the theoretical and methodological topics listed in the program. For the part of "Soil Bioengineering Application" the examination also includes simple exercises and technical calculations. The oral exam will also test the communication skill of the student. |
| Extended program | Lectures: Soil bio-engineering: definition, aims, historical development, technical limits. Watershed definition. Morphology and hydrology of watersheds. Concentration time. Modelization of hydrological processes at basin level. Measure and statistical analysis of rainfall. Rainfall intensity-duration-frequency curves. Rainfall-runoff models (empirical, semi-empirical, analytical): rational and SCS-CN methods). Quantification of peak discharge. Water currents on open channels in the case of uniform flow. Stream classification and characteristics. Sediment transport (outlines). Concepts of critical velocity and equilibrium slope. Soil water erosion modelization: the RUSLE equation. Bioengineering techniques for soil protection against erosion and shallow landslides. Design criteria of live cribwalls and construction phases. Bioengineering techniques for stream protection and reclamation. Desing criteria of stone and wooden weirs. Intercations between water flow and vegetation. Maintenance of riparian vegetation.Training: Estimation of the concentration time and of the peak discharge. Channel design.

| Type of study-unit | Obbligatorio (Required) |
| Language of instruction | Italian |
| Contents | The main objective is to provide the students with the basic knowledge on soil genesis, the relationships between soil and environmental factors, soil evaluation and conservation, the study of the soil in the field, cartography. |
| Reference texts | Dazzi C. - Fondamenti di pedologia. Ed. Le Penseur Sequi P. - Fondamenti di chimica del suolo, Patron Editore Nyle C. Brady e Ray R. Weil - Nature and properties of soils. Prentice Hall. USA Guidelines for Soil Description. FAO, 2006. Available online. |
| Educational objectives | The course takes into consideration the basic elements which constitute the soil and its functioning. The main objective is to provide the students with all the elements to manage the soil in a sustainable way, to prevent degradation and water erosion. The main acquired knowledge will be: factors of soil formation, soil properties, soil evaluation and conservation. At the end of the course the students should be able to recognize a soil type and to interpret the morphological and analytical information useful to evaluate the soil quality, have elements to understand soil variability in the landscape and the environmental sustainability of a given soil use. |
| Prerequisites | In order to better understand the topics covered in the teaching, the student must have knowledge of chemistry, agronomy |
| Teaching methods | The course is organized as follows: -lessons in the classroom on all the topics of the course -practical training in the classroom (cartography) and in the field: opening of soil profiles, soil description, interpretation of the morphological data |
| Other information | Attending the lessons is optional, but strongly advised. Lesson will be held at the Department of Agricultural, Food and Environmental Sciences, Borgo XX Giugno 74, Perugia. Other info at http://dsa3.unipg.it |
| Learning verification modality | The final examination includes an oral exam consisting of a discussion lasting about 40 minutes, aimed at ascertaining the level of knowledge and understanding achieved by the student on the theoretical and methodological topics listed in the program. The examination also includes reading and interpretation of topographic and soil maps. The oral exam will also test the communication skill of the student. |
| Extended program | The soil and its role in the environment Factors of soil formation Name and description of the soil horizons, elements of soil classification Soil physical and chemical properties Soil evaluation and conservation Elements of cartography |
