27370 - Hydraulic Agro-Forestry

Learning outcomes

To provide tools for landscape survey and analysis, giving a startpoint for handling soil and water conservation issues, in an approach integrated with the environment and its hydrological, hydraulic and geomorphological aspects.

Course contents

Surface runoff erosion, slope instability, mass movement. Geotechnics characterisation rocks versus water.

Soil loss predictions , modelling soil erosion, Universal Soil Loss Equation.Action of watercourses .  Surface water circulation.  Hydrography and patterns of stream drainage area

Elements of fluvial hydrology  Water flow, measurement methods. Coefficient of discharge.Modes of transport: suspension, traction and solution

Sediment yield from river basin. Basin water balance, drainage coefficient.Discharge hydrograph, characteristic curves

Study of precipitation and water flow extremes for the design of fluvial engineering works: climate possibility distributions, Gumbel statistical analysis, storm return time.

Subsurface water ,  water table and artesian aquifers, wells.

Biothecnical slope protection : water control and slope protection. Role of vegetation in the stability and protection of slopes.. Rules, hydrogeology principles

Wind erosion protection : hydraulic-forestry engineering techniques.

Topic-specific cartography :  Reading and interpretation of topic-specific maps (slope, lithologic and slope-distribution stability, etc.)

The practical exercises concern the following topics and others of the program: the reading of the basic and thematic topographic maps, the identification of a water catchment area, the hydrography, the isoipse and the reconstruction of profiles and slope calculations.

A group work is proposed: how to deal with the realization of a naturalistic engineering arrangement project referring to a real case. The project will be presented to colleagues as PP, together with the report applies to the final exam.

access with students' institutional credentials.


The teaching of Agro-forestry Hydraulics consists of educational visits in the field with the support of technical staff of public bodies and practical exercises, also.
There will be seminars in collaboration with Technicians (Region, Reclamation Consortia, etc.) and Researchers on specific topics.
The teaching of Soil erosion and bioengineering settlements consists of 4 cfu and is borrowed from agro-forestry hydraulics. The program excludes two topics that will be indicated by the teacher.
