Academic Year 2011/2012

  • Docente: Donatella Pavanelli
  • Credits: 4
  • SSD: AGR/08
  • Language: Italian
  • Teaching Mode: Traditional lectures
  • Campus: Bologna
  • Corso: First cycle degree programme (L) in Land and agro-forestry Sciences (cod. 0870)

Learning outcomes

The program aims to develop an interdisciplinary knowledge and technical skills base for understanding soils resources and sustainable land management in a rural development context and from a systems perspective.

During the program problems of soil erosion,  soil conservation, environmental degradation, sustainability and rural development issues are addressed from the farm to the catchment scale .

Course contents

   Surface Geodynamics .

   Agents and types of erosion :  water erosion, wind erosion, ice erosion, gravity erosion

Meteoric degradation : physics and chemical weathering

Nature of rainfall erosion. Determinants of  rainfall erosion.

Surface runoff erosion :  detachment, transport and sedimentation of soil particles.

Types of  slope water erosion.

Mass movement: types of slope movements, causes of slope movements, indicators of  

slope instability.
