Slidepacks - four sets of slides and notes for students and teachers
A series of four slidepacks are available:
  • Sediment Control
  • Sediment monitoring techniques
  • Soil erosion
  • Irrigation and the environment

Sediment Control
A set of 24 slides illustrates the sediment problems met by irrigation engineers, and some of the exclusion/extraction devices that have been developed to overcome or reduce these problems.

The pack also contains a series of notes for students and teachers, covering:
- Sediment excluders
- Sediment extractors
- Vortex Tube
- Tunnel extractor
- Sluiced settling basins

Sediment monitoring
A set of 24 slides, provides examples of some of the sediment monitoring techniques which have been developed by engineers. They are used throughout the developing world in catchments of varying size.

The pack also contains a series of notes for students and teachers covering:
- Plot studies
- Sub-catchment studies
- Large catchment studies
- Equipment and measurement procedures employed for monitoring wash and bed load
- Sample analysis
- Reservoirs

Soil erosion
A set of 24 slides provides examples of different soil erosion problems and processes frequently encountered in the field.

 

The pack also contains a series of notes for students and teachers covering:

  • Erosion processes
    - Sheet erosion
    - Rill and gulley erosion
    - Landslips
  • Accelerated erosion
  • Prevention and control of erosion
    - Physical techniques
    - Vegetative Techniques
    - Cultivation techniques
    - Recapture

Irrigation and the environment
A set of 24 slides illustrates some of the environmental problems that can accompany irrigation developments. Mitigating measures are also highlighted.


The pack also contains a series of notes for students and teachers, covering:
- Environmental changes at project level
- Wider environmental impacts
- Habitat and species conservation
