Sample interview questions: How do you approach the assessment and management of soil erosion and degradation?
Sample answer:
Assessment of Soil Erosion and Degradation
- Field Assessment:
- Conduct visual inspections to identify areas of erosion and degradation, noting the severity and extent.
- Collect soil samples for analysis of physical and chemical properties (e.g., texture, bulk density, pH).
- Monitor runoff and sediment load using sediment traps or field instrumentation.
- Remote Sensing:
- Utilize aerial photography, satellite imagery, and Lidar data to map erosion patterns and identify vulnerable areas.
- Analyze vegetation cover and land use changes using remote sensing techniques.
- Modeling:
- Apply erosion prediction models (e.g., RUSLE, GIS-based models) to estimate potential soil loss and sediment yield.
- Incorporate climatic data, soil characteristics, and topography into modeling efforts.
Management of Soil Erosion and Degradation
- Erosion Control Measures:
- Implement terracing, contour farming, and mulching to reduce soil detachment by wind and water.
- Utilize vegetative cover crops or windbreak… Read full answer
