Objective
To acquaint and equip with the process of soil and water conservation design of erosion control structures.

Theory

UNIT I
Concepts of soil and water conservation; relevance of soil and water conservation in agriculture; productivity loss due to soil erosion; moisture stress and moisture excess.

UNIT II
Types of soil erosion; mechanics of water erosion of soil; effect of land preparation and cultivation practices on soil erosion; theories of sediment yield and sediment transport; bed load movement; measurement of sediment yield and sediment transport; effective life of dams and water detention structures; effect of soil erosion on the life of multi-purpose river valley projects; soil erosion loss and fertility; erosion in water conveyance systems;

UNIT III
