Soil and Water Conservation Engineering

 

Course Objective:

To impart knowledge on principles of soil erosion, sediment transport, and soil and water conservation measures for sustainable watershed management.

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.

Activity: Assignment on soil erosion risk assessment

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.

Activity: Field visit to a watershed/soil conservation structure

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.

Activity: Poster presentation on smart irrigation systems.

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

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