Full Unit-wise Syllabus

Unit I – Soil Erosion Principles, Assessment

Soil erosion processes, types, and mechanics with estimation methods such as SCS-CN and USLE/RUSLE. Land capability, gully classification, permissible soil loss, and introduction to watershed modelling.

Activities: Assignment on soil erosion risk assessment

Unit II – Agronomic, Mechanical Erosion Control Measures

Agronomic practices and mechanical measures including bunding, terracing, and waterways. Design and application of gully control structures for slope and watershed protection.

Activities: Field visit to a watershed/soil conservation structure

Unit III – Water Conservation, Harvesting Techniques

In-situ moisture conservation, rainwater harvesting, micro-catchments; morphometric analysis for catchment yield estimation, Design of farm ponds, check dams, and integrated watershed management practices.

Activities: Poster presentation on smart irrigation systems.

Unit IV – Sedimentation, Watershed Sustainability

Sediment transport mechanisms, estimation, and reservoir sedimentation analysis. Sediment control methods and sustainability aspects of watershed systems.

Activities: Case study analysis of reservoir sedimentation problem and control strategies.
