Soil And Water Conservation Engineering Training

Week 1: Soil erosion – introduction, causes and types;Geological and accelerated erosion; Erosion agents;Factors affecting and effects of erosion.

Week 2: Water erosion – Mechanics and forms; Gullies –Classification & stages of development

Week 3: Soil loss estimation – Universal soil loss equation(USLE) and modified USLE; Rainfall erosivity -estimation by KE>25 and EI 30 methods; Soil erodibility and other management factors.

Week 4: Measurement of soil erosion – Runoff plots, soil samplers.

Week 5: Water erosion control measures – agronomical measures – contour farming, strip cropping, conservation tillage and mulching; Engineering measures– Bunds and terraces.

Week 6: Bunds – contour and graded bunds – design and surplussing arrangements

Week 7: Terraces – level and graded broad base terraces, bench terraces – planning, design and layout procedure, contour stonewall and trenching.

Week 8: Gully and ravine reclamation – principles of gully control – vegetative measures, temporary structures and diversion drains.
