Course content

The aim of the course is to provide the knowledge and the skills needed to apply watershed management techniques also by soil bioengineering measures

Lectures

Watershed definition. Morphology and hydrology of watersheds. 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. Soil bio-engineering: definition, aims, historical development, technical limits. Bioengineering techniques for soil protection against erosion and shallow landslides.   Bioengineering techniques for stream protection and reclamation.  


Exercises 
Determination of rainfall intensity-duration frequency curves. Estimation of the concentration time and of the peak discharge. Channel design. Determination of the equilibrium slope and of the number and high of dikes. Design of river dikes and retention basins. 

Supplement

Description and quantification of the main hydrological processes at the watershed level with particular reference at rainfall and runoff phenomena.  Definition, aims and techniques of soil-bioengineering. Examples of methods applied in watershed and stream restoration.

Mode of delivery

Theoretical lessons and practical training
